Three routes under /onboarding, reachable from the lock screen and from the shell, since a second wallet is the same flow as the first. Create picks a scheme (ML-DSA-65 by default), shows the 24 words once, and stands the backup challenge between seeing them and having a wallet; a failed challenge drops the phrase on the Rust side and starts over. Restore takes a phrase and a scheme, with a note that the same phrase gives a different account under each. Import opens a native file chooser through tauri-plugin-dialog, the first plugin, granted only dialog:allow-open with its reason in the capability file; the path goes to Rust, which reads the file. Every path ends unlocked on the accounts page. Driven through the WebKit inspector against the dev node: create wrote onboard_test.json and unlocked; restoring the same phrase under a new name produced the same address; importing a fixture file with the right password opened it and with a wrong one mapped to wrong_password. The chooser itself is a Wayland window nothing here can type into, so the permission is verified by the open promise staying pending rather than rejecting; CLAUDE.md and the inspector script now say so.

blackbeard wallet
A desktop wallet for post-quantum chains, Quantus first.
Linux, Windows and macOS; installable on Fedora with dnf.
Shape
The wallet is a Rust cargo workspace with a Tauri shell and a React webview. That split is the security model, not a convenience: every key, signature, decoded transaction and amount lives on the Rust side, and the webview only renders what a Tauri command hands it. Nothing that could serialise a secret is reachable from JavaScript.
crates/
wallet-entities/ domain types and the IPC wire protocol; exported to TypeScript
wallet-core/ wallet logic and the ports it is written against
wallet-data/ adapters behind those ports: keystore, cache, RPC, provider APIs
wallet-app/ the Tauri binary; commands are one-line shims into core
ui/ Vite + React + TypeScript webview
The ports in wallet-core are what make "any post-quantum chain" a profile
rather than a rewrite:
KeySchemeturns a seed and a path into a signer. ML-DSA-65 and ML-DSA-87 now; whatever the next chain uses later.ChainAdapterknows one chain: balances, building and submitting a transaction, watching it. The Substrate adapter is driven by runtime metadata plus a small per-chain profile (ss58 prefix, decimals, signature enum, transaction extensions, signing-context rule, coin type).SwapProvideris a swap venue. NEAR Intents first.FiatRampbuilds a provider session through a relay on our infrastructure, which holds the provider secrets, and opens it in the system browser.
The wallet is post-quantum only. Classical chains appear only as transit legs of a swap or ramp; the wallet never derives a secp256k1 or ed25519 key.
Why these choices
Quantus signs extrinsics with ML-DSA, hashes public keys with Poseidon2 for
the account id, and shields mining rewards behind a Plonky2 wormhole whose
prover is minutes of native CPU. All of that exists as Rust crates and nothing
else, so the core is Rust. Tauri is the house desktop convention
(~/git/architecture/generic.md §4) and the only shell that packages rpm, deb,
msi and dmg with a Rust-owned IPC boundary out of the box.
NEAR's post-quantum work (their MPC fork with threshold ML-DSA-87) is not yet able to sign a Quantus extrinsic, so the swap module is built and tested against chains NEAR Intents already lists, with Quantus as a registry entry that lights up when the bridge does.
Building
pnpm --dir ui install
cargo tauri dev --config crates/wallet-app/tauri.conf.json # from crates/wallet-app: cargo tauri dev
cargo test --workspace # also regenerates ui/src/api/generated
The CI gate is cargo fmt --check, cargo clippy -D warnings, cargo test,
and the webview's typecheck, lint and build. Run them before claiming done.
Work
Work is filed before it is done. Epics carry the epic label and an external
definition of done; their steps carry child, in dependency order, at
https://git.lair.cafe/blackbeard/wallet/issues. A commit that finishes a
child closes it (Closes #N); when an investigation contradicts an issue, the
correction is a comment on the issue, dated, not a surprise in a diff.
