jwinterm 416fa53c17 feat: Nostr-native data models + initial schema
models/db.rs: User keyed by pubkey_hash/nostr_pubkey/username (pubkey_hash and
seed_fingerprint peppered at rest); Wallet, Session (platform=extension|web|nostr),
UserKey, GrinSlatepack, AuditLog. Dropped all telegram/discord/social-identity
columns and every tip/social/swap struct (swaps land as their own feature unit).

migrations/20260622000001_initial_schema: consolidated clean schema; enum types;
UNIQUE on identity columns; FK ON DELETE (CASCADE/SET NULL) for self-service
erasure; indexes on every lookup column. PostgreSQL 13+.

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/capabilities and 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.
