Layer global middleware onto build_router (applies to every route, shared by main + the test harness): - CORS: configurable allowed origins via CORS_ALLOWED_ORIGINS; empty -> allow any origin, which is safe here because auth is a Bearer token (no cookies, no ambient credentials). Credentials are never allowed. - Body limit: 1 MiB global backstop (handlers already validate tighter per field); /wallet/lws/submit_tx overrides to ~2 MiB+ for raw Monero tx hex. - Timeout: 60s request backstop (above the chain clients' ~30s timeouts, so their errors surface first; bounds any slow handler). Uses the http-aware tower_http TimeoutLayer (-> 408), not tower::timeout (fallible, rejected by axum's Infallible Router). - gzip compression + request tracing (outermost). Adds cors_allowed_origins config + the tower-http "timeout" feature. Per-IP rate limiting is deliberately separate (needs ConnectInfo) — next commit. All gates green; integration tests pass through the layered router (CORS/timeout/ compression/body-limit are oneshot-safe). openapi unchanged.
smirk-backend-core
Open, self-hostable backend for the Smirk non-custodial, multi-chain wallet. It provides the chain-access and identity surface a Smirk wallet needs — authentication, per-chain wallet access (Bitcoin, Litecoin, Monero, Wownero, Grin), the Grin slatepack relay, and Nostr-based identity — so anyone can run their own backend and a Smirk wallet can connect to it.
Status: early, under active development. Interfaces and the database schema may change before the first tagged release. Not yet recommended for production self-hosting.
What it is
- Non-custodial. The server never holds spend keys or seeds. It brokers access to blockchain data and relays wallet-to-wallet messages.
- Open core, feature-flagged. Every feature ships in this codebase and is
toggled per deployment; the wallet reads
GET /api/v1/capabilitiesand adapts to what a given backend offers. - Identity via "Sign in with Smirk". Authentication uses a seed-derived Nostr key (NIP-98); the server stores only public keys.
- Privacy first. No PII is required to use it; operator and user privacy are explicit design goals.
Architecture
Rust + Axum, PostgreSQL via sqlx. The public HTTP contract is generated from the handlers with utoipa (OpenAPI), which in turn drives the wallet's generated TypeScript client — one source of truth, checked for drift in CI.
Quickstart
cp .env.example .env # then fill in DATABASE_URL, JWT_SECRET, node URLs
cargo run # starts the API server
A full self-hosting guide (node requirements, reverse proxy, Tor admin onion,
backups) will live in docs/ as it stabilises.
