 There have been some additions in the code above comparing with retrieving runtime constants. In these cases, since we are making a query to the actual chain, we use the `await` syntax to retrieve the information. Since the API is Promise-based, this means we can also rewrite the above to follow a Promise pattern,

 The above example certainly does not quite look as ergonomic and clean, but the API needs to understand (a) which are all the calls we need to make and (b) the calls and their params (if required). So breaking it down -

 - `api.query.timestamp.now` - the timestamp is passed naked without any params. Also note that we do not call it while passing, but rather only provides a reference to the function, i.e. we do not have the expected `()` at the end. (This could also be of the form `[api.query.timestamp.now]`, aligning with subsequent entries)
- `[api.query.system.accountNonce, ADDR]` - the nonce query is passed as an array containing the function (once again naked), followed by the parameters that apply.

 When the API connects to a node, one of the first things it does is to retrieve the metadata. The metadata, effectively provides data in the form of `api.<type>.<module>.<section>` that fits into one of the following categories -

- [consts](../substrate/constants.md) - All runtime constants, e.g. `api.consts.balances.creationFee`. These are not functions, rather accessing the endpoint immediately yields the result as defined.
- [query](../substrate/storage.md) - All chain state, e.g. `api.query.balances.freeBalance(<accountId>)`.

 - [tx](../substrate/extrinsics.md) - All extrinsics, e.g. `api.tx.balances.transfer(<accountId>, <value>)`.

 In both these case we can instruct the TypeScript compiler that the type we are expecting in `Index` and `Balance` respectively, not just pure `Codec`. This means that functions like `.toNumber()` is available on both these types - as opposed to just the [general type defaults](types.basics.md#everything-is-a-type) with `.toHex()` and friends.

-▸ **setBalance**(who: `Address`, new_free: `Compact<Balance>`, new_reserved: `Compact<Balance>`)
- **summary**: Set the balances of a given account.  This will alter `FreeBalance` and `ReservedBalance` in storage. it will also decrease the total issuance of the system (`TotalIssuance`). If the new free or reserved balance is below the existential deposit, it will reset the account nonce (`system::AccountNonce`).  The dispatch origin for this call is `root`.  # <weight> - Independent of the arguments. - Contains a limited number of reads and writes. # </weight>
-
-▸ **transfer**(dest: `Address`, value: `Compact<Balance>`)
- **summary**: Transfer some liquid free balance to another account.  `transfer` will set the `FreeBalance` of the sender and receiver. It will decrease the total issuance of the system by the `TransferFee`. If the sender's account is below the existential deposit as a result of the transfer, the account will be reaped.  The dispatch origin for this call must be `Signed` by the transactor.  # <weight> - Dependent on arguments but not critical, given proper implementations for input config types. See related functions below. - It contains a limited number of reads and writes internally and no complex computation.  Related functions:  - `ensure_can_withdraw` is always called internally but has a bounded complexity. - Transferring balances to accounts that did not exist before will cause `T::OnNewAccount::on_new_account` to be called. - Removing enough funds from an account will trigger `T::DustRemoval::on_unbalanced` and `T::OnFreeBalanceZero::on_free_balance_zero`.  # </weight>

-▸ **call**(dest: `Address`, value: `Compact<BalanceOf>`, gas_limit: `Compact<Gas>`, data: `Bytes`)
- **summary**: Makes a call to an account, optionally transferring some balance.  * If the account is a smart-contract account, the associated code will be executed and any value will be transferred. * If the account is a regular account, any value will be transferred. * If no account exists and the call value is not less than `existential_deposit`, a regular account will be created and any value will be transferred.
-
-▸ **claimSurcharge**(dest: `AccountId`, aux_sender: `Option<AccountId>`)
- **summary**: Allows block producers to claim a small reward for evicting a contract. If a block producer fails to do so, a regular users will be allowed to claim the reward.  If contract is not evicted as a result of this call, no actions are taken and the sender is not eligible for the reward.
-
-▸ **instantiate**(endowment: `Compact<BalanceOf>`, gas_limit: `Compact<Gas>`, code_hash: `CodeHash`, data: `Bytes`)
- **summary**: Instantiates a new contract from the `codehash` generated by `put_code`, optionally transferring some balance.  Instantiation is executed as follows:  - The destination address is computed based on the sender and hash of the code. - The smart-contract account is created at the computed address. - The `ctor_code` is executed in the context of the newly-created account. Buffer returned after the execution is saved as the `code` of the account. That code will be invoked upon any call received by this account. - The contract is initialized.
-
-▸ **putCode**(gas_limit: `Compact<Gas>`, code: `Bytes`)
- **summary**: Stores the given binary Wasm code into the chain's storage and returns its `codehash`. You can instantiate contracts only with stored code.

Returns the voter deposit to `signed`.  # <weight> - O(1). - Two fewer DB entries, one DB change. # </weight>
-
-▸ **removeMember**(who: `Address`)
- **summary**: Remove a particular member from the set. This is effective immediately.  Note: A tally should happen instantly (if not already in a presentation period) to fill the seat if removal means that the desired members are not met.
-
-▸ **retractVoter**(index: `Compact<u32>`)
- **summary**: Remove a voter. All votes are cancelled and the voter deposit is returned.  The index must be provided as explained in [`voter_at`] function.  Also removes the lock on the balance of the voter. See [`do_set_approvals()`].  # <weight> - O(1). - Two fewer DB entries, one DB change. # </weight>

-▸ **setApprovals**(votes: `Vec<bool>`, index: `Compact<VoteIndex>`, hint: `SetIndex`, value: `Compact<BalanceOf>`)
- **summary**: Set candidate approvals. Approval slots stay valid as long as candidates in those slots are registered.  Locks `value` from the balance of `origin` indefinitely. Only [`retract_voter`] or [`reap_inactive_voter`] can unlock the balance.  `hint` argument is interpreted differently based on: - if `origin` is setting approvals for the first time: The index will be checked for being a valid _hole_ in the voter list. - if the hint is correctly pointing to a hole, no fee is deducted from `origin`. - Otherwise, the call will succeed but the index is ignored and simply a push to the last chunk with free space happens. If the new push causes a new chunk to be created, a fee indicated by [`VotingFee`] is deducted. - if `origin` is already a voter: the index __must__ be valid and point to the correct position of the `origin` in the current voters list.  Note that any trailing `false` votes in `votes` is ignored; In approval voting, not voting for a candidate and voting false, are equal.  # <weight> - O(1). - Two extra DB entries, one DB change. - Argument `votes` is limited in length to number of candidates. # </weight>
-
-▸ **setDesiredSeats**(count: `Compact<u32>`)

NOTE: if `origin` has already assigned approvals via [`set_approvals`], it will NOT have any usable funds to pass candidacy bond and must first retract. Note that setting approvals will lock the entire balance of the voter until retraction or being reported.  # <weight> - Independent of input. - Three DB changes. # </weight>

The dispatch origin for this call must be _Signed_ by the stash account.  # <weight> - Independent of the arguments. Moderate complexity. - O(1). - Three extra DB entries.  NOTE: Two of the storage writes (`Self::bonded`, `Self::payee`) are _never_ cleaned unless the `origin` falls below _existential deposit_ and gets removed as dust. # </weight>
-
-▸ **bondExtra**(max_additional: `Compact<BalanceOf>`)
- **summary**: Add some extra amount that have appeared in the stash `free_balance` into the balance up for staking.  Use this if there are additional funds in your stash account that you wish to bond. Unlike [`bond`] or [`unbond`] this function does not impose any limitation on the amount that can be added.  The dispatch origin for this call must be _Signed_ by the stash, not the controller.  # <weight> - Independent of the arguments. Insignificant complexity. - O(1). - One DB entry. # </weight>

The dispatch origin for this call must be _Signed_ by the controller, not the stash.  # <weight> - The transaction's complexity is proportional to the size of `targets`, which is capped at `MAX_NOMINATIONS`. - Both the reads and writes follow a similar pattern. # </weight>
-
-▸ **setController**(controller: `Address`)
- **summary**: (Re-)set the controller of a stash.  Effects will be felt at the beginning of the next era.  The dispatch origin for this call must be _Signed_ by the stash, not the controller.  # <weight> - Independent of the arguments. Insignificant complexity. - Contains a limited number of reads. - Writes are limited to the `origin` account key. # </weight>

- **summary**: The ideal number of validators.
-
-▸ **unbond**(value: `Compact<BalanceOf>`)
- **summary**: Schedule a portion of the stash to be unlocked ready for transfer out after the bond period ends. If this leaves an amount actively bonded less than T::Currency::minimum_balance(), then it is increased to the full amount.  Once the unlock period is done, you can call `withdraw_unbonded` to actually move the funds out of management ready for transfer.  No more than a limited number of unlocking chunks (see `MAX_UNLOCKING_CHUNKS`) can co-exists at the same time. In that case, [`Call::withdraw_unbonded`] need to be called first to remove some of the chunks (if possible).  The dispatch origin for this call must be _Signed_ by the controller, not the stash.  See also [`Call::withdraw_unbonded`].  # <weight> - Independent of the arguments. Limited but potentially exploitable complexity. - Contains a limited number of reads. - Each call (requires the remainder of the bonded balance to be above `minimum_balance`) will cause a new entry to be inserted into a vector (`Ledger.unlocking`) kept in storage. The only way to clean the aforementioned storage item is also user-controlled via `withdraw_unbonded`. - One DB entry. </weight>
-
-▸ **validate**(prefs: `ValidatorPrefs`)
- **summary**: Declare the desire to validate for the origin controller.  Effects will be felt at the beginning of the next era.  The dispatch origin for this call must be _Signed_ by the controller, not the stash.  # <weight> - Independent of the arguments. Insignificant complexity. - Contains a limited number of reads. - Writes are limited to the `origin` account key. # </weight>

- **summary**: Remove any unlocked chunks from the `unlocking` queue from our management.  This essentially frees up that balance to be used by the stash account to do whatever it wants.  The dispatch origin for this call must be _Signed_ by the controller, not the stash.  See also [`Call::unbond`].  # <weight> - Could be dependent on the `origin` argument and how much `unlocking` chunks exist. It implies `consolidate_unlocked` which loops over `Ledger.unlocking`, which is indirectly user-controlled. See [`unbond`] for more detail. - Contains a limited number of reads, yet the size of which could be large based on `ledger`. - Writes are limited to the `origin` account key. # </weight>

-▸ **eraSlashJournal**(`EraIndex`): `Vec<SlashJournalEntry>`
- **summary**: All slashes that have occurred in a given era.
-
-▸ **forceEra**(): `Forcing`
- **summary**: True if the next session change will be a new era regardless of index.
-
-▸ **invulnerables**(): `Vec<AccountId>`
- **summary**: Any validators that may never be slashed or forcibly kicked. It's a Vec since they're easy to initialize and the performance hit is minimal (we expect no more than four invulnerables) and restricted to testnets.
-
-▸ **ledger**(`AccountId`): `Option<StakingLedger>`
- **summary**: Map from all (unlocked) "controller" accounts to the info regarding the staking.
-
-▸ **minimumValidatorCount**(): `u32`
- **summary**: Minimum number of staking participants before emergency conditions are imposed.
-
-▸ **nominators**(`AccountId`): `(Vec<AccountId>, Linkage<AccountId>)`
- **summary**: The map from nominator stash key to the set of stash keys of all validators to nominate.
-
-▸ **payee**(`AccountId`): `RewardDestination`
- **summary**: Where the reward payment should be made. Keyed by stash.
-
-▸ **slashRewardFraction**(): `Perbill`
- **summary**: The percentage of the slash that is distributed to reporters.  The rest of the slashed value is handled by the `Slash`.
-
-▸ **slotStake**(): `BalanceOf`
- **summary**: The amount of balance actively at stake for each validator slot, currently.  This is used to derive rewards and punishments.
-
-▸ **stakers**(`AccountId`): `Exposure`
- **summary**: Nominators for a particular account that is in action right now. You can't iterate through validators here, but you can find them in the Session module.  This is keyed by the stash account.
-
-▸ **validatorCount**(): `u32`
- **summary**: The ideal number of staking participants.
-
-▸ **validators**(`AccountId`): `(ValidatorPrefs, Linkage<AccountId>)`

-▸ **allExtrinsicsLen**(): `Option<u32>`
- **summary**: Total length (in bytes) for all extrinsics put together, for the current block.
-
-▸ **allExtrinsicsWeight**(): `Option<Weight>`
- **summary**: Total weight for all extrinsics put together, for the current block.
-
-▸ **blockHash**(`BlockNumber`): `Hash`
- **summary**: Map of block numbers to block hashes.
-
-▸ **digest**(): `DigestOf`
- **summary**: Digest of the current block, also part of the block header.
-
-▸ **eventCount**(): `EventIndex`
- **summary**: The number of events in the `Events<T>` list.
-
-▸ **events**(): `Vec<EventRecord>`
- **summary**: Events deposited for the current block.
-
-▸ **eventTopics**(`Null, Hash`): `Vec<(BlockNumber,EventIndex)>`
- **summary**: Mapping between a topic (represented by T::Hash) and a vector of indexes of events in the `<Events<T>>` list.  The first key serves no purpose. This field is declared as double_map just for convenience of using `remove_prefix`.  All topic vectors have deterministic storage locations depending on the topic. This allows light-clients to leverage the changes trie storage tracking mechanism and in case of changes fetch the list of events of interest.  The value has the type `(T::BlockNumber, EventIndex)` because if we used only just the `EventIndex` then in case if the topic has the same contents on the next block no notification will be triggered thus the event might be lost.
-
-▸ **extrinsicCount**(): `Option<u32>`
- **summary**: Total extrinsics count for the current block.
-
-▸ **extrinsicData**(`u32`): `Bytes`
- **summary**: Extrinsics data for the current block (maps an extrinsic's index to its data).

- **summary**: Extrinsics root of the current block, also part of the block header.
-
-▸ **nextWeightMultiplier**(): `WeightMultiplier`
- **summary**: The next weight multiplier. This should be updated at the end of each block based on the saturation level (weight).
-
-▸ **number**(): `BlockNumber`
- **summary**: The current block number being processed. Set by `execute_block`.

-▸ **parentHash**(): `Hash`
- **summary**: Hash of the previous block.
-
-▸ **randomMaterial**(): `(i8,Vec<Hash>)`
- **summary**: Series of block headers from the last 81 blocks that acts as random seed material. This is arranged as a ring buffer with the `i8` prefix being the index into the `Vec` of the oldest hash.
