+Upgrade priority: Low. Recommended for users wanting to keep updated with chain changes.
+
+Contributed:
+
+- Clean Websocket states on disconnects (Thanks to https://github.com/ianhe8x)
+- Support for C-like indexed enums (Thanks to https://github.com/xlc)
+
+Changes:
+
+- Adjust council derives to cater for current-generation candidate mapping

+- Update election types as per latest Substrate
+- Add types for the new gilt module
+- Upgrade to the latest Substrate metadata
+- Adjust package detection to check for local monorepo dependencies
+- Ensure that metadata `.toJSON()` does apply type aliasses
+
+
+## 3.10.2 Feb 23, 2021
+
+Upgrade priority: Medium. Recommended for users of chains where `MultiAddress` is in-use and blocks are decoded.
+
+Changes:
+
+- Fix decoding for `MultiAddress` enum where non-`AccountId` variable-lengths are provided as part of a stream
+- Added known Polkadot 28 upgrade block
+- Update for latest Substrate contracts `Schedule` types
+
+
+## 3.10.1 Feb 22, 2021
+
+Upgrade priority: Low.
+
+Changes:
+
+- Adjust ConsumedWeight types to align with Rust module code
+- Check for connection status in subscription unsubscribe
+- Adjust staking reward derives ordering for better performance
+- Adapt detection imports to remove `.json` dependencies (Better behavior using Node.js with ESM)
+
+
+## 3.9.3 Feb 16, 2021
+
+Upgrade priority: Low. Recommended for parachain builders since it contains the updated parachain types.
+
+Changes:
+
+- Adjusted parachain `PersistedValidationData` structure
+
+
+## 3.9.2 Feb 15, 2021
+
+Upgrade priority: Low. Recommended for parachain builders since it contains the latest parachain types.
+
+Contributed:
+
+- Update README links (Thanks to https://github.com/wirednkod)
+
+Changes:
+
+- Added missing Culmulus `ParachainInherentData` & `MessageQueueChain` types
+- Add alias for `system_unstable_networkState` RPC
+
+
+## 3.9.1 Feb 14, 2021
+
+Upgrade priority: Low.
+
+- **Important** The `Result<T, E>` has been updated in the generation and the base types to follow the Rust version 100%. This means `{as, is}Error` is now available as `{as, is}Err` on the `Result` type. The older versions can still be used, but the `*Error` interfaces are now marked as deprecated.
+
+Changes:
+
+- Adjust `Result<T, E>` interface to be 100% compatible with the Rust version
+- Add the `2028` upgrade to the known upgrades (optimizing certain `.at` queries)
+- Adjust council derives to cater for latest Substrate & Polkadot
+- Adjust Rococo know type definitions to cater for the latest update
+- Update types for latest Polkadot/Substrate
+- Add generic arguments for TypeScript users to `.entries/.keys` to deal with the key typings
+
+
+## 3.8.1 Feb 7, 2021
+
+Upgrade priority: Low. Recommended for users of the latest Substrate master, especially using contracts.
+
+- **Important** The `api-contract` `Code` now supports deploying the code and a contract in on operation. This aligns with the latest Substrate where code cannot be uploaded with a contract. The `createBlueprint` is therefore deprecated, use `code.tx.<constructor>(...)` to deploy code. (Compatible with both old and new versions of Substrate)
+
+Contributed:
+
+- Add support for latest Frontier RPCs (Thanks to https://github.com/jnaviask)
+- Fix user-supplied signed extensions type signature (Thanks to https://github.com/ntduan)
+
+Changes:
+
+- Expand `api-contract` to allow for `Code` to deploy contract alongside code. `createBlueprint` is now deprecated, replaced by `createContract` or the preferred `code.tx.<constructor>`, which uploads and deploys the code in one operation. This aligns with the current Substrate master contracts implementation.
+- Allow for signed extensions to be supplied inside type bundles
+- Ensure that the auto-connect state is checked on auto-connections (respecting disconnect)
+- Added `CancelProxy` to `ProxyTypes on Polkadot, Kusama & Westend
+- Updated to latest Substrate metadata
+
+
+## 3.7.3 Feb 2, 2021
+
+Changes:
+
+- Added Polkadot upgrade block for runtime 27 (known checkpoint optimization)
+
+
+## 3.7.2 Feb 2, 2021
+
+Changes:
+
+- Adjusted the `Keys` type for the 28 runtime on Kusama, Polkadot & Westend
+
+
+## 3.7.1 Feb 1, 2021
+
+Upgrade priority: Low. However recommended for current Substrate master, Polkadot and Rococo users and those wishing to support the upcoming Polkadot 28 runtime with the new `MultiAddress`.
+
+- **Breaking change** As indicated in the 3.5.1 release notes, the `Address`/`LookupSource` defaults have now been adjusted for `MultiAddress`. If your chain does not use these types, explicitly add the correct `Address`/`LookupSource` types. This new extensible format is mean to cater for all address types into the future, removing a lot of discrepancies between chains.
+
+Contributed:
+
+- Extraction of the block author on Moonbeam (Thanks to https://github.com/joelamouche)
+- Cleanup logs with HTTP providers, no subs (Thanks to https://github.com/Tbaut)
+
+Changes:
+
+- Allow `.slice` operator on the `Vec` type
+- Apply `MultiAddress` as a default
+- Adds support for the upcoming Polkadot 28 and Kusama 2028 runtimes
+- Add checkpoint for Kusama 2027 upgrade
+- Update all parachain types (as per latest Rococo)
+- Correctly use relay blockNumber in parachain validation data
+- remove information log for capabilities detection (creates confusion)
+- Remove explicit references to `global`, use the `x-global` detection
+- Remove explicit `module` in `package.json` (exports map available)
+
+
+## 3.6.1 Jan 24, 2020
+
+Upgrade priority: Medium if not already on at least 3.3.1. The next upgrade of Kusama/Polkadot requires it.
+
+- **Breaking change** To support chains with multiple tokens, such as bridges, the `ChainProperties` type now returns an array of tokens and decimals (instead of singular values) in the `token{Decimals, Symbol}` getters. Additionally, this means that the `registry` interfaces has been changes, to `registry.chainDecimals: number[]` and `registry.chainTokens: string[]`. Where used the `[0]` index will return the first value if only interested in a single, for a straight conversion.
+
+Changes:
+
+- Allow for the detection of on-chain capabilities as available (e.g. `AccountData`, `ValidatorPrefs`)
+- Cater for multiple tokens and decimals in the chain the chain `system.properties` (as per the chain specification)
+- Add a `instances: { [key]: [module1, module2] }` definition in teh bundle types, allowing for multiple instances (e.g. Balances)
+- Adjust the `api-derive` for balances to retrieve values via `instances` as well as across multiple modules
+- Ensure all types are registered for all metadata typegen steps
+- Add `rpc.payment.queryFeeDetails` RPC endpoint
+- Update types & metadata to latest Substrate
+- Move the `@polkadot/x-rxjs` package into the common repo
+- Allow doc generation for errors/events (markdown outputs)
+
+
+## 3.5.1 Jan 18, 2020
+
+Upgrade priority: Low. Recommended for parachain developers.
+
+- **Important** The default for Substrate on the Address types are `MultiAddress`. It is recommended that chains add explicit definitions for `Address` and `LookupSource` in their types, instead of relying on the API-defaults. A future update will swap the API defaults to align with Substrate.
+- **Important** Like the above changes in Substrate, the `AccountInfo` structure has also changed. It is recommended that chain developers explicitly add `AccountInfo: 'AccountInfoWithRefCount'` for the version with `refCount` on and `AccountInfoWithProviders` for the latest Substrate version. As per the above, the API defaults will be changed to align with Substrate.
+
+Contributed:
+
+- Apply correct TypeScript type for `toBigInt()` (Thanks to https://github.com/ianhe8x)
+- Expand type definitions for storage key tuples (Thanks to https://github.com/monitz87)
+- Adjust bounty derive to cater for non-council chains (Thanks to https://github.com/ekowalsk)
+
+Changes:
+
+- Remove recursion in vector/struct U8a stream decoding
+- Availability of staking made optional in session length calcs (era does require it)
+- Updates to parachain types, ensuring it has coverage for all the latest
+- Update all Rococo types to the latest (session keys, session reports, parachain indexes)
+- Update known upgrade checkpoints fo WestEnd
+- Add types of the lottery module in Substrate
+- Add and extend types for the crowdloan module in Polkadot
+- Adjust node-template to default to `MultiAddress` on specVersion >= 100
+
+
+## 3.4.1 Jan 11, 2020
+
+Upgrade priority: Low. Fixes for parachain types, `.entries()` (with no values) and `event.is(...)` checks, users of these interfaces will have benefit.
+
+- **Breaking change** The `derive.chain.{getBlock, subscribeNewBlocks}` now return `SignedBlockExtended`, all with the actual extrinsics and events mapped. Users of the latter interface should take note.
+
+Contributed:
+
+- Fix `SessionKeys{6-9}` definitions (Thanks to https://github.com/icodezjb)
+- Support `Vec<(a, b)>` in enums (Thanks to https://github.com/monitz87)
+- Add motions to bounty derive (Thanks to https://github.com/ekowalsk)
+
+Changes:
+
+- `derive.chain.getBlock()` now maps events to extrinsics via `.extrinsics` getter
+- Ensure dispatchInfo is extracted on failed extrinsics (`getBlock` derive)
+- Allow specification of additional signed extrinsic via API options
+- Add missing parachain types, `ParaGenesisArgs`
+- Correct `EthTransaction` type (as per the correct cargo crate)
+- Update with latest contract types for Substrate master
+- Update alias mapping for asset palette (including Substrate starting defaults)
+- Allow `.entries()` call where 0 keys are present
+- Fix `.is` on events not checking the correct index
+- Construction of `i*` types ow correctly checks for max positive/negative
+
+
+## 3.3.1 Jan 4, 2021
+
+Upgrade priority: Low. Recommended for users of frontier evm module with additional types.
+
+Contributed:
+
+- Expand bounty derives (Thanks to https://github.com/ekowalsk)
+- Adjust known-types (Thanks to https://github.com/mikiquantum)
+
+Changes:
+
+- Parallelize the API-init RPC calls for faster overall startup
+- Add `ExitReason` types for the frontier evm module
+- Adjust checks for indexed/non-indexed module checks (metadata decoration)
+- Apply module aliases on constants (aligning with events, extrinsics)
+- Allow for use of `system.ss58Prefix` as exposed (current Substrate master)
+- Correct use of api-contract `blockWeights.maxBlock` in estimation
+- Build metadata docs & interfaces with section aliases
+- Update to latest Substrate master metadata in tests
+
+
+## 3.2.1 Dec 27, 2020
+
+Upgrade priority: Low. Recommended for users of parachains.
+
+Contributed:
+
+- Adjust metadata `.asV12` type signature (Thanks to https://github.com/yjhmelody)
+
+Changes:
+
+- Add `api.{errors, events, query, tx}.<section>.<name>.is(...)`
+- Remove support for staking pre Substrate 2.0
+- Add all frontier types & RPCs
+- Support `AccountInfo` with new provider/consumer refCount structure
+- Additional Cumulus parachain types
+- Consistently format number JSON based on bitLength
+- Cleanup metadata -> api dependencies
+- Update `@polkadot/util` to 5.2.1
+
+
+## 3.1.1 Dec 20, 2020
+
+Upgrade priority: Low. Recommended for users of parachains.
+
+Contributed:
+
+- Additional parachain types (Thanks to https://github.com/joelamouche)
+- Support for multi queries with `HttpProvider` (Thanks to https://github.com/ianhe8x)
+- Configurable error logging with `createTypeUnsafe` (Thanks to https://github.com/dvdplm)
+
+Changes:
+
+- Adjust core type creation, removing storage duplication
+- Update parachain types to support Rococo v1
+- Adjust bounties derive to cater for new Substrate namespaces (& move to bounties)
+- Mark `detectPackage` as known side-effect
+- Add `detectPackage` to `@polkadot/metadata` (a number of requests on this)
+- Adjust x-rxjs wrapper to expose all methods, incl. Node.js esm fixes
+- Update to latest Substrate static metadata
+- Update `@polkadot/util` to 5.1.1
+
+
+## 3.0.1 Dec 14, 2020
+
+Upgrade priority: Low. Recommended for the next Kusama/Polkadot upgrades due to additional types and those following chains following Substrate master closely.
+
+**Important** While this package contains no external interface changes, it now compiles and ships both cjs and esm modules. This means that modern bundlers will have more information for tree-shaking available. Additionally when using Node with `.mjs` extensions, the esm version imports will be used on recent Node versions. Adding an export map, as here, may have some impacts so a major semver bump is advised. There may be (small) dragons hiding in the dark corners...
+
+Contributed:
+
+- Injection of derives via typesBundle (Thanks to https://github.com/pr0fedt)
+- Added derives for bounties (Thanks to https://github.com/krzysztof-jelski)
+
+Changes:
+
+- Build and expose both cjs and esm via exports map
+- Inject RPC definitions for typesBundle, allowing per-spec configuration
+- Added `query.<section>.<method>.sizeAt(hash, [...params])` for all storage
+- Add new Substrate consumed Weight types
+- Expand `SessionKeys<n>` definitions (up to 9)
+- Cleanup circular `Type` <-> `Text` definitions
+- Cleanup circular `Metadata` <-> `TypeRegistry` imports
+- Update `@polkadot/util` to 5.0.1
+
+
+## 2.10.1 Dec 7, 2020
+
+Upgrade priority: Low. Recommended when following Substrate master and/or parachains development, contains the latest types for both.
+
+- **Breaking change** If using the `staking.query` derive, you now need to pass flags as to which values to retrieve
+
+Changes:
+
+- Ensure that maximum era is limited to `consts.system.blockHashCount` (don't overflow on very low blocktimes)
+- Apply current Polkadot master parachain types
+- Apply current Substrate master asset types
+- Add `system_{addLogFilter, resetLogFilter}` RPCs
+- Adjust tests for latest Substrate metadata
+- Adjust staking derives to be more performant (flags indicate which query values to retrieve)
+- Add account derive to cater for the availability of identities
+- Use `import type` in all cases
+
+
+## 2.9.1 Nov 30, 2020
+
+Upgrade priority: Low. No major changes when on at least 2.8.2. Users encouraged to upgrade to at least that patch.
+
+- **Breaking change** The API will now not attempt to queue calls made while not connected and send on connection. Rather when making a call and the RPC node is not connected, an error will be thrown.
+
+Contributed:
+
+- Add typegen capability for custom RPCs (Thanks to https://github.com/holygits)
+
+Changes:
+
+- Remove rpc-core send queue, only allow sends while connected
+- Adjust staking derive for `electedInfo` to contain details of current validators
+- Extract identity-only derive from `accounts.info` for simpler reusability
+- Add types for Substrate master node (to allow for consistent swapping to `MultiAddress`)
+- Adjust `Bytes` with `.slice` to be consistent for `Uint8array` extensions (already released in 2.8.2 as a bugfix)
+
+
+## 2.8.1 Nov 23, 2020
+
+Upgrade priority: Low. Recommended if using Substrate master with new `MultiAddress`.
+
+Contributed:
+
+- Export `derive.chain.getBlock` (Thanks to https://github.com/lovesh)
+
+Changes:
+
+- Expand `MultiAddress` construction with multi type detection
+- Rename `GenericLookupSource` to `IndicesLookupSource` (internal use)
+- Cleanup list retrievals with `Raw` data results for undecodable entries
+- Export actual version via `RegistryMetadata`
+- Dedupe bn.js (one version shared between dependencies)
+
+
+## 2.7.1 Nov 16, 2020
+
+Upgrade priority: Medium. Recommended for users of Polkadot/Kusama and api-contract users.
+
+Changes:
+
+- Allow for `ExtrinsicSignature` overrides (defaults to `MultiSignature`)
+- Update api-contract `Blueprint` to allow for optional salt (auto if not provided)
+- Support for ink! `.contract` files (in addition to ABI `.json`)
+- Fix contract event decoding with pass-through of raw `Bytes`
+- Fix support for enum encoding in api-contract
+- Support new contract `Schedule` type as per Substrate
+- Update Kusama/Polkadot known upgrade blocks
+- Adjust typegen generated `@polkadot/types` imports
+- Adjust internal `@polkadot/types` imports/exports (overall bundle sizes)
+
+
+## 2.6.1 Nov 9, 2020
+
+Upgrade priority: Low. Should be done alongside an update to `@polkadot/util` to 4.0
+
+Changes:
+
+- Adjust auto-gas to contract RPC call to 5 * 10 ^ 12 (align with Rust)
+- Adjust derive `AccountId` check to take Ethereum-compatible chains into account
+- Fallback for chains with invalid council proposal data in derives
+- Bump static v12 Metadata (tests) to latest Substrate version
+- Bump `@polkadot/{util,util-crypto}` to 4.0 (optimized WASM layers)
+
+
+## 2.5.1 Nov 2, 2020
+
+Upgrade priority: Low. Recommended for `api-contract` developers.
+
+- **Breaking change** Substrate changed the `ContractExecResult` from `api.rpc.contracts.call`. The API does have pass-through support for both old and new variants via the `Contract` interface, however it means the structure has changed to accommodate the new Substrate structure. Refer to the [docs for the latest interface](https://polkadot.js.org/docs/api-contract/start/contract.read) (including `isSuccess/isError` -> `isOk/isErr`, and the availability of the `gasConsumed`)
+
+Contributed:
+
+- Dedup similar types on generation (Thanks to https://github.com/monitz87)
+
+Changes:
+
+- `Contract` execution will now return contract events decoded in the result
+- Add `.dryRun` on extrinsics (alongside `.paymentInfo` usage)
+- Add `system_syncState` and `syncstate_genSyncSpec` RPCs
+- Enhance error reporting, `Call` indicates explicit call as found

+- Expand Rococo known types to cater for v1 (specVersion 10)
+- `registry.hash` now returns an `H256` object (as opposed to raw Uint8Array)
+- Use utility logger in all relevant error messages (consistency in logging)
+- Add `derive.council.proposal(<hash>)` for retrieval of a single (expanded) proposal
+- Correctly and transparently format type generation types (allowing for nested variants)
+
+
+## 2.4.1 Oct 26, 2020
+
+Upgrade priority: Low. No breaking changes, however it does move `api-contract` forward with additional features.
+
+Contributed:
+
+- Add support for both `{i,u}256` types on contracts (Thanks to https://github.com/seanyoung)
+
+Changes:
+
+- Add `.keysAt` & `.entriesAt` to query maps at a specific blockHash
+- Adjust ordering of type injection, any `types: { ... }` definitions not have precedence
+- Correctly format Tuples in both RPC and const definitions as part of type generation
+- Add node-template to known types (tracking inside API), remove warnings for the spec
+- Add initial implementation for new Substrate `MultiAddress` type
+- Add `api.derive.chain.subscribeNewBlocks` for full block retrievals
+- Contracts identifiers to `.{exec, read}('name', ...)` now matches on both snake_case and camelCase (consistency)
+- Cleanup contracts serialization for messages to allow both to and from
+- Add deserialization of contract events against the ABI
+- Adjust contracts metadata parsing to be future-proof with type retrievals
+- Add tests for Solang into contracts, re-organize layout per type
+
+
+## 2.3.1 Oct 19, 2020
+
+Upgrade priority: Low. Recommended for `api-contract` developers and those using large messages via Node.js WS.
+
+Contributed:
+
+- Adjust frame size for Node.js WebSockets (Thanks to https://github.com/mnaamani)
+- Update warnings to reflect new docs URLs (Thanks to https://github.com/aphelionz)
+
+Changes:
+
+- Expose `dispatch{Error, Info}` on all `.tx` results (less boilerplate on info checks)
+- Add missing primitive types inside contracts type parsing
+- Adjust api-contract to expose `Contract.{query, tx}.<message>` and `Blueprint.tx.<constructor>`
+- Rework contracts registry to be generic to all scale-info definitions
+- Allow for auto-max weight on contract read/exec (useful in estimation)
+- Fix memoization where `BigInt` params are passed
+
+
+## 2.2.1 Oct 12, 2020
+
+Upgrade priority: Low.
+
+- **Breaking change** `@polkadot/api-contract` now only supports ink! 3.0-rc1 and later formats. Users of ink! 2.1 are recommended to stay on an older version until upgraded.
+
+Contributed:
+
+- Add latest Ink! types (Thanks to https://github.com/ascjones & https://github.com/kwingram25)
+- Add base for new contract metadata parsing (Thanks to https://github.com/ascjones & https://github.com/kwingram25)

+- Adjust `Schedule` type for latest Substrate (contracts)
+- Allow snake_case to be handled transparently in structs
+- Full new api-contract developer interfaces (Code, Blueprint, Contract)

 - [@polkadot/api](packages/api/) The API library, providing both Promise and RxJS Observable-based interfaces. This is the main user-facing entry point.
 - [@polkadot/api-derive](packages/api-derive/) Derived results that are injected into the API, allowing for combinations of various query results (only used internally and exposed on the Api instances via `api.derive.*`)
 - [@polkadot/api-metadata](packages/api-metadata/) Base extrinsic, storage and constant injectors for injection

-## development
-
-Contributions are welcome!
-
-To start off, this repo (along with others in the [@polkadot](https://github.com/polkadot-js/) family) uses yarn workspaces to organise the code. As such, after cloning, its dependencies _should_ be installed via `yarn`, not via npm; the latter will result in broken dependencies.
-
-To get started -
-
-1. Clone the repo locally, via `git clone https://github.com/polkadot-js/api <optional local path>`
-2. Ensure that you have a recent version of Node.js, for development purposes [Node 10](https://nodejs.org/en/) is recommended.
-3. Ensure that you have a recent version of Yarn, for development purposes [Yarn >=1.10.1](https://yarnpkg.com/docs/install) is required.
-4. Install the dependencies by running `yarn`
-5. Build the everything via `yarn run build`
-6. You can also launch the API Docs, via `yarn vuepress dev docs`
-7. Access the docs via [http://localhost:8080](http://localhost:8080)

-# Cookbook
-
-The cookbook hosts small code snippets in a question-answer format. It does not walk you through the whole setup, like the [basic examples](../examples/), but rather aims to answer some questions around specific uses. It also does not replace the [getting started FAQ](../start/FAQ.md), rather this is focussed explicitly on code samples, instead of general trouble-shooting for common mishaps.
-
-These questions are added as they do come up and the hope is that the snippets here is will be useful to others, instead of just the original person who asked on a specific use-case. As of today, it is only making a start and not fully comprehensive yet - check back early, check back often.
-
-## Sections
-
-The following cookbook sections are available -
-
-- [Blocks](blocks.md) - Snippets around working with blocks and headers
-- [Storage](storage.md) - Snippets for working with storage
-- [Transactions](tx.md) - Snippets for working with transactions
-
-... more to come.
-
-## Contribute
-
-And as always, if you have an addition to make, or a question to ask any [any PRs](https://github.com/polkadot-js/api/tree/master/docs) or [issues](https://github.com/polkadot-js/api/issues) are appreciated. The initial content was generate from exactly such questions, either in Riot chat or as submitted as issues.

-# Blocks
-
-The building blocks for each blockchain. As such there are a number of examples for working with blocks and headers, that could be useful.
-
-## How do I retrieve the header/extrinsic hash from blocks?
-
-A block hash refers to the hash over the header, the extrinsic hash refers to the hash of the encoded extrinsic. Since all objects returned by the API implements the `.hash => Hash` getter, we can simply use this to view the actual hash.
-
-```js
-// returns Hash
-const blockHash = await this.api.rpc.chain.getBlockHash(blockNumber);
-// returns SignedBlock
-const signedBlock = await this.api.rpc.chain.getBlock(blockHash);
-
-// the hash for the block, always via header (Hash -> toHex()) - will be
-// the same as blockHash above (also available on any header retrieved,
-// subscription or once-off)
-console.log(signedBlock.header.hash.toHex());
-
-// the hash for each extrinsic in the block
-signedBlock.block.extrinsics.forEach((ex, index) => {
-  console.log(index, ex.hash.toHex());
-});
-```
-
-## How do I extract the block author?
-
-The block author is encoded inside the consensus logs for the block. To extract, you need to decode the log (which the API does do) and then map the index of the validator to the list of session validators. This extraction is however available on the api derive for new head subscriptions, which returns an extended header with the author populated (assuming that the digest logs are known).
-
-```js
-// subscribe to all new headers (with extended info)
-api.derive.chain.subscribeNewHeads((header) => {
-  console.log(`#${header.number}: ${header.author}`);
-});
-```
-
-For a single header only, the derives also contain a `getHeader`, which once again returns a header extended with the author -
-
-```js
-// retrieve the last header (hash optional)
-const header = await api.derive.chain.getHeader();
-
-console.log(`#${header.number}: ${header.author}`);
-```
-
-## How do I view block extrinsic information?
-
-The transactions are included in a signed block as part of the extrinsics - some of these will be unsigned and generated by the block author and some of these may be submitted from external sources and be signed. (Some palettes do use unsigned transactions, so signed/unsigned is not an indication of origin). To retrieve the block and display the transaction information, we can do the following -
-
-```js
-// no blockHash is specified, so we retrieve the latest
-const signedBlock = await this.api.rpc.chain.getBlock();
-
-// the information for each of the contained extrinsics
-signedBlock.block.extrinsics.forEach((ex, index) => {
-  // the extrinsics are decoded by the API, human-like view
-  console.log(index, ex.toHuman());
-
-  const { isSigned, meta, method: { args, method, section } } = ex;
-
-  // explicit display of name, args & documentation
-  console.log(`${section}.${method}(${args.map((a) => a.toString()).join(', ')})`);
-  console.log(meta.documentation.map((d) => d.toString()).join('\n'));
-
-  // signer/nonce info
-  if (isSigned) {
-    console.log(`signer=${ex.signer.toString()}, nonce=${ex.nonce.toString()}`);
-  }
-});
-```
-

-# Storage
-
-Here you will find snippets for working with storage.
-
-## How do I check for storage existence?
-
-In the metadata, for each storage item a fallback is provided. This means that when an entry does not exist, the fallback (which is the default value for the type) will be provided. This means, that querying for a non-existent key (unless an option), will yield a value -
-
-```js
-// retrieve Option<StakingLedger>
-const ledger = await api.query.staking.ledger('EoukLS2Rzh6dZvMQSkqFy4zGvqeo14ron28Ue3yopVc8e3Q');
-// retrieve ValidatorPrefs (will yield the default value)
-const prefs = await api.query.staking.validators('EoukLS2Rzh6dZvMQSkqFy4zGvqeo14ron28Ue3yopVc8e3Q');
-
-console.log(ledger.isNone, ledger.isSome); // true, false
-console.log(JSON.stringify(prefs.toHuman())); // {"commission":"0"}
-```
-
-In the second case, the non-existent prefs returns the default/fallback value for the storage item. So in this case we don't know if the value is set to 0 or unset. Existence can be checked by using the storage size, which would be zero if nothing is stored.
-
-```js
-// exists
-const sizeY = await api.query.staking.validators.size('DB2mp5nNhbFN86J9hxoAog8JALMhDXgwvWMxrRMLNUFMEY4');
-// non existent
-const sizeN = await api.query.staking.validators.size('EoukLS2Rzh6dZvMQSkqFy4zGvqeo14ron28Ue3yopVc8e3Q');
-
-console.log(sizeY.isZero(), sizeY.toNumber()); // false 4
-console.log(sizeN.isZero(), sizeY.toNumber()); // true 0
-```
-
-## How do I use .entries()/.keys() on double maps?
-
-As [explained elsewhere](../start/api.query.other.md#map-keys-entries) each map-type storage entry exposes the entries/keys helpers to retrieve the whole list. In the case of double maps, with the addition of a single argument, you can retrieve either all entries or a subset based on the first map key.
-
-In both these cases, entries/keys operate the same way, `.entries()` retrieving `(StorageKey, Codec)[]` and `.keys()` retrieving `StorageKey[]`
-
-```js
-// Retrieves the entries for all slashes, in all eras (no arg)
-const allEntries = await api.query.staking.nominatorSlashInEra.entries();
-
-// nominatorSlashInEra(EraIndex, AccountId) for the types of the key args
-allEntries.forEach(([{ args: [era, nominatorId] }, value]) => {
-  console.log(`${era}: ${nominatorId} slashed ${value.toHuman()}`);
-});
-```
-
-While we can retrieve only the keys for a specific era, using a argument for the first part of the doublemap (as defined here, an `EraIndex`) -
-
-```js
-// Retrieves the keys for the slashed validators in era 652
-const slashedKeys = await api.query.staking.nominatorSlashInEra.keys(652);
-
-// key args still contains [EraIndex, AccountId] decoded
-console.log(`slashed: ${slashedKeys.map(({ args: [era, nominatorId] }) => nominatorId)`);
-```

-# Transactions
-
-A blockchain is no fun if you are not submitting transactions. Or at least if somebody is not submitting any. Here you will find some snippets for dealing with some common issues.
-
-## How do I estimate the transaction fees?
-
-In addition to the `signAndSend` helper on transactions, `.paymentInfo` (with the exact same parameters) are also exposed. Using the same sender, it applies a dummy signature to the transaction and then gets the fee estimation via RPC.
-
-```js
-// estimate the fees as RuntimeDispatchInfo, using the signer (either
-// address or locked/unlocked keypair) (When overrides are applied, e.g
-//  nonce, the format would be `paymentInfo(sender, { nonce })`)
-const info = await api.tx.balances
-  .transfer(recipient, 123)
-  .paymentInfo(sender);
-
-// log relevant info, partialFee is Balance, estimated for current
-console.log(`
-  class=${info.class.toString()},
-  weight=${info.weight.toString()},
-  partialFee=${info.partialFee.toHuman()}
-`);
-```
-
-## How do I get the decoded enum for an ExtrinsicFailed event?
-
-Assuming you are sending a tx via `.signAndSend`, the callback yields information around the tx pool status as well as any events when `isInBlock` or `isFinalized`. If an extrinsic fails via `system.ExtrinsicFailed` event, you can retrieve the error, if defined as an enum on a module.
-
-```js
-api.tx.balances
-  .transfer(recipient, 123)
-  .signAndSend(sender, ({ status, events }) => {
-    if (status.isInBlock || status.isFinalized) {
-      events
-        // find/filter for failed events
-        .filter(({ section, method }) =>
-          section === 'system' &&
-          method === 'ExtrinsicFailed'
-        )
-        // we know that data for system.ExtrinsicFailed is
-        // (DispatchError, DispatchInfo)
-        .forEach(({ data: [error, info] }) => {
-          if (error.isModule) {
-            // for module errors, we have the section indexed, lookup
-            const decoded = api.registry.findMetaError(error.asModule);
-            const { documentation, method, section } = decoded;
-
-            console.log(`${section}.${method}: ${documentation.join(' ')}`);
-          } else {
-            // Other, CannotLookup, BadOrigin, no extra info
-            console.log(error.toString());
-          }
-        });
-    }
-  });
-```
-
-## How do I send an unsigned extrinsic?
-
-For most runtime modules, transactions need to be signed and validation for this happens node-side. There are however modules that accepts unsigned extrinsics, an example would be the Polkadot/Kusama token claims (which is here used as an example).
-
-```js
-// construct the transaction, exactly as per normal
-const utx = api.tx.claims.claim(beneficiary, ethSignature);
-
-// send it without calling sign, pass callback with status/events
-tx.send(({ status }) => {
-  if (status.isInBlock) {
-    console.log(`included in ${status.asInBlock}`);
-  }
-});
-```
-
-The signing is indicated by the first byte in the transaction, so in this case we have called `.send` on it (no `.sign` or `.signAndSend`), so it will be sent using the unsigned state, without signature attached.
-
-## How can I batch transactions?
-
-Polkadot/Substrate provides a `utility.batch` method that can be used to send a number of transactions at once. These are then executed from a single sender (single nonce specified) in sequence. This is very useful in a number of cases, for instance if you wish to create a payout for a validator for multiple eras, you can use this method. Likewise, you can send a number of transfers at once. Or even batch different types of transactions.
-
-```js
-// construct a list of transactions we want to batch
-const txs = [
-  api.tx.balances.transfer(addrBob, 12345),
-  api.tx.balances.transfer(addrEve, 12345),
-  api.tx.staking.unbond(12345)
-];
-
-// construct the batch and send the transactions
-api.tx.utility
-  .batch(txs)
-  .signAndSend(sender, ({ status }) => {
-    if (status.isInBlock) {
-      console.log(`included in ${status.asInBlock}`);
-    }
-  });
-```
-
-## How do I take the pending tx pool into account in my nonce?
-
-The `system.account` query will always contain the current state, i.e. it will reflect the nonce for the last known block. As such when sending multiple transactions in quick succession (see batching above), there may be transactions in the pool that has the same nonce that `signAndSend` would apply - this call doesn't do any magic, it simply reads the state for the nonce. Since we can specify options to the `signAndSend` operation, we can override the nonce, either by manually incrementing it or querying it via `rpc.system.accountNextIndex`.
-
-```js
-for (let i = 0; i < 10; i++) {
-  // retrieve sender's next index/nonce, taking txs in the pool into account
-  const nonce = await api.rpc.system.accountNextIndex(sender);
-
-  // send, just retrieving the hash, not waiting on status
-  const txhash = await api.tx.balances
-    .transfer(recipient, 123)
-    .signAndSend(sender, { nonce });
-}

-# Make a Transfer with allowed block permissions 
-
-This transactions shows you how to add a nonce and a valid length of blocks a transaction is valid for. 
-
-This is important because as an account drops below the exsistential limit (0.1 dots) it gets pruned from the state tree. If it is added back its nonce starts at 0 again and is now vulnerable to replay attacks.

-# typegen
-
-This is a sample TypeScript project [with full source & config on GithHub](https://github.com/polkadot-js/api/tree/master/docs/examples/promise/90_typegen), that uses `@polkadot/typegen` to generate type definitions that can be used to decorate the `@polkadot/api`. It uses both types defined for the specific chain as well as the chain metadata to generate TypeScript interfaces. This means that interfaces such as `api.query.*`, `api.tx.*` and `api.consts.*` will be decorated based on chain-specific information, instead of an un-augmented catch-all definition.
-
-**NOTE** This is built using the updates in the `1.4.0` api track and as such it uses the latest (at the time of writing) `@polkadot/api 1.4.0`. If you want to play on your own, it is also suggested that you use the `1.4+` series since some generation types have moved around internally, making it easier to augment.
-
-## Packages
-
-For the packages we need from the `@polkadot/*` we have added `@polkadot/api` (we want to do API stuff) and `@polkadot/typegen` (to generate the actual interfaces). So our scripts and dependencies inside `package.json` contain the following -
-
-```json
-{
-  "scripts": {
-    "build": "yarn generate:defs && yarn generate:meta",
-    "generate:defs": "ts-node --skip-project node_modules/.bin/polkadot-types-from-defs --package sample-polkadotjs-typegen/interfaces --input ./src/interfaces",
-    "generate:meta": "ts-node --skip-project node_modules/.bin/polkadot-types-from-chain --package sample-polkadotjs-typegen/interfaces --endpoint ./edgeware.json --output ./src/interfaces",
-    "lint": "tsc --noEmit --pretty"
-  },
-  "dependencies": {
-    "@polkadot/api": "^1.4.0"
-  },
-  "devDependencies": {
-    "@polkadot/typegen": "^1.4.0",
-    "ts-node": "^8.6.2",
-    "typescript": "^3.8.2"
-  }
-}
-```
-
-We will delve into the setup and running the scripts and what they do in a short bit, but as of now just notice that we are running the scripts via `ts-node`. Since we supply our definitions as `*.ts` files, this is important otherwise they will not be parsable. `build` will just run both the types and meta generators (in that order, so metadata can use the types) and we have a `lint` that can just check that everything is as it is meant to be.
-
-## Metadata setup
-
-The idea here is to use the actual chain metadata to generate the actual api augmented endpoints. The metadata we are adding here (in addition to the user types), is from the Edgeware Berlin testnet. So this is a real-world example of configuring the API for a specific substrate chain. For the metadata retrieval, we just ran a simple curl command to get it from the node -
-
-`curl -H "Content-Type: application/json" -d '{"id":"1", "jsonrpc":"2.0", "method": "state_getMetadata", "params":[]}' http://localhost:9933`
-
-And then add the full JSONPC output as received to the `edgeware.json` file as specified by the generation command. A trimmed version would look like -
-
-```json
-{"jsonrpc":"2.0","result":"0x6d6574610b6c185379737....","id":29}
-```
-
-The generator can also use a `wss://` as an `--endpoint` param as part of the generation, but in most cases you would want a static metadata to work from in development, hence we are actually adding it here.
-
-## Types setup
-
-The types are defined in the `src/interfaces` folder. While this repo contains a number of generated files in there as well, you basically only need to manually add the following -
-
-- `src/interfaces/definitions.ts` - this just exports all the sub-folder definitions in one go
-- `src/interfaces/<module>/definitions.ts` - type definitions for a specific module
-
-This structure fully matches what is available in the `@polkadot/type/interfaces` folder, so the structure is setup based on the convention used in the `@polkadot/types` library. The generating scripts will expect something matching this since the same underlying code is actually used inside `@polkadot/types` as well. The top-level `interfaces/` folder can be name anything, however the internal content structure need to match what is defined above.
-
-For the top-level the definition file has the following contents -
-
-```js
-export { default as signaling } from './signaling/definitions';
-export { default as treasuryRewards } from './treasuryRewards/definitions';
-export { default as voting } from './voting/definitions';
-```
-
-As explained above, it really is just a re-export of the definitions, so they are all easily accessible to the outside, i.e. we will use this import inside our own code to use the definitions in API initialization. The generation scripts will load this file to determine which types it needs to import. By the `@polkadot/types` convention, match the export names with the folders (preferably your runtime module names), the generation scripts will use these names to find the correct folders to output the generated `types.ts` to.
-
-For each of the folders, `signaling`, `treasuryRewards` and `voting` another `definitions.ts` file is contained within. Looking at the one from `signaling`, it contains this -
-
-```js
-export default {
-  types: {
-    ProposalRecord: {
-      index: 'u32',
-      author: 'AccountId',
-      stage: 'VoteStage',
-      transition_time: 'u32',
-      title: 'Text',
-      contents: 'Text',
-      vote_id: 'u64'
-    },
-    ProposalContents: 'Vec<u8>',
-    ProposalTitle: 'Vec<u8>'
-  }
-}
-```
-
-Just the type definitions (the structure of which you should be familiar with), nested inside a `types: {...}` container. This allows us future extension points, i.e. there is some work to expose the custom RPC types alongside, so that would become another key on a per-module basis.
-
-In the above, you will note that the `ProposalRecord` references a type for `voting`, i.e. `VoteStage`. The type generation and resolution will determine where the type comes from, and provide the required imports on generation.
-
-Looking at the example in this repo, it also has `augment*`, `index.ts` and `types.ts` files in the interfaces folder. These are all generated, and will be re-generated when the generator is run - so all edits to these files will be lost. The only requirement for user-edits are the `definitions.ts` files.
-
-## Generating
-
-Now that both the metadata and types setup is completed, we just run the build command via `yarn build` and magically (assuming you didn't have the `augment*` and other generated files), these files will be added. When running this command, the console should display something like -
-
-```
-> yarn build
-$ yarn generate:defs && yarn generate:meta
-$ ts-node --skip-project \
-  node_modules/.bin/polkadot-types-from-defs \
-    --package sample-polkadotjs-typegen/interfaces \

-
-sample-polkadotjs-typegen/src/interfaces/augment-api.ts
-	Generating
-	Writing
-
-✨  Done in 4.04s.
-```
-
-Now if we check the actual output against the source via `yarn lint`, we would see that valid output has been generated -
-
-```
-> yarn lint
-$ tsc --noEmit --pretty
-✨  Done in 2.28s.
-```
-
-## Peering at the output
-
-We are ready to use all these generated types this after some TS config. If you take a look at the generated `src/signaling/types.ts`, you would see generated TS interfaces, such as -
-
-```js
-import { Struct } from '@polkadot/types/codec';
-import { Bytes, Text, u32, u64 } from '@polkadot/types/primitive';
-import { AccountId } from '@polkadot/types/interfaces/runtime';
-import { VoteStage } from 'sample-polkadotjs-typegen/interfaces/voting';
-
-/** @name ProposalContents */
-export interface ProposalContents extends Bytes {}
-
-/** @name ProposalRecord */
-export interface ProposalRecord extends Struct {
-  readonly index: u32;
-  readonly author: AccountId;
-  readonly stage: VoteStage;
-  readonly transition_time: u32;
-  readonly title: Text;
-  readonly contents: Text;
-  readonly vote_id: u64;
-}
-
-/** @name ProposalTitle */
-export interface ProposalTitle extends Bytes {}
-```
-
-As mentioned earlier, here you will notice the `import { VoteStage }`, the generator has determined that `voting` exports that interface and has added the required imports.
-
-## TypeScript config
-
-Now that we have files generated, it is time to make TypeScript aware of the types and add an explicit override into out `tsconfig.json`. After some changes, the paths in the config looks as follow (comments are in the actual config file here) -
-
-```json
-{
-  "compilerOptions": {
-    "paths": {
-      "sample-polkadotjs-typegen/*": ["src/*"],
-      "@polkadot/api/augment": ["src/interfaces/augment-api.ts"],
-      "@polkadot/types/augment": ["src/interfaces/augment-types.ts"]
-    }
-  }
-}
-```
-
-Effectively what we do above is tell the TypeScript compiler to not use the built-in API augmentation, but rather to replace it with our version. This means that all types from these are injected not by the substrate-latest-master version, but rather with what we have defined above.
-
-## Usage
-
-For simple usage, we have added the `src/index.ts` file that show how the metadata and types actually decorate the API. In addition, we also have setup instructions included here.
-
-```js
-// We need to import the augmented definitions "somewhere" in our project, however since we have
-// it in tsconfig as an override and the api/types has imports, it is not strictly required here.
-// Because of the tsconfig override, we could import from '@polkadot/{api, types}/augment'
-import './interfaces/augment-api';
-import './interfaces/augment-types';
-
-// all type stuff, the only one we are using here
-import type { VoteRecord } from './interfaces';
-
-// external imports
-import { ApiPromise } from '@polkadot/api';
-import { createType } from '@polkadot/types';
-
-// our local stuff
-import * as definitions from './interfaces/definitions';
-
-async function main (): Promise<void> {
-  // extract all types from definitions - fast and dirty approach, flatted on 'types'
-  const types = Object.values(definitions).reduce((res, { types }): object => ({ ...res, ...types }), {});
-
-  const api = await ApiPromise.create({
-    types: {
-      ...types,

-# ApiPromise Examples
-
-Here you will find a list of examples that takes you through the basics of connecting to a local node, retrieving data from the Node and chain and execute transactions on the chain. It uses the [[ApiPromise]] interface.
-
-## Prerequisites
-
-For the following examples, you need a local node. It is usually convenient testing with:
-
-```
-substrate --dev
-```
-
-## Running the examples
-
-From each folder, run `yarn` to install the required dependencies and then run `yarn start` to execute the example against the running node.
-
-## Development accounts
-
-Some of the examples use the following accounts:
-
-- Alice: `5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY`
-- Bob: `5FHneW46xGXgs5mUiveU4sbTyGBzmstUspZC92UhjJM694ty`
-
-Those accounts are easy to add if you don't have/see them. The seed of Alice's account is `//Alice` (via `keyring.addUri(...)`, dev seed implied) and the seed of Bob is... well you guess...
