Six entity query modules on Database, all explicit-column (no SELECT *), legacy methods dropped: - sessions: create + active-lookup by (already-peppered) refresh_token_hash, revoke/revoke-all (race-aware bool), touch, cleanup-expired - user_keys: upsert (ON CONFLICT user_id+asset+key_type), list, get-by-asset - audit: log_action + recent-by-user/action - grin_slatepacks: relay create/fetch/pending/respond/finalize/cancel/expire - login_events: salted IP hash, retention sweep, erasure purge (LoginStats only) - restore_attempts: peppered fingerprint + salted IP (never raw), rate-limit counts, 7-day sweep migrations/...02: login_events + restore_attempts tables (keyed-hash columns, covering indexes for the aggregations). Shared unique_violation_as + hash_ip helpers on Database.
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.
