Users prove identity with keys. You charge in BTC (or priced in fiat) over Nostr. This repo is the Rust workspace behind the REST daemon, core protocol, and native building blocks.

You want	Portal gives you
Passwordless sign-in	Key handshake + Nostr; auth guide
One-off and recurring pay	Single and subscription flows; payments
Tickets / tokens	Cashu paths; tokens

Quick start

Fastest path: spin up a hosted instance on PortalHub—no server to run.

Self-host the REST daemon:

docker run -d -p 3000:3000 \
  -e PORTAL__AUTH__AUTH_TOKEN=$(openssl rand -hex 32) \
  -e PORTAL__NOSTR__PRIVATE_KEY=<your-64-char-hex-key> \
  getportal/sdk-daemon:0.4.2

Then curl http://localhost:3000/health should return OK.

Client SDKs

Where	Install / link
TypeScript / JavaScript	npm install portal-sdk
Java	JitPack
Anything with HTTP	REST API

Workspace layout

Rust crates live under crates/. The portal crate is not a top-level workspace member but is the shared core every service binary depends on.

Crate	What it is
portal	Protocol types, Nostr conversations, message router
portal-rest	rest binary: Bearer auth, streaming events, webhooks
portal-app	Package app: UniFFI staticlib + runtime (wallet, relays, payment UI hooks)
portal-wallet	PortalWallet implementations: NWC, Breez Spark
portal-sdk	Async SDK: relay pool + high-level send/receive helpers
portal-rates	Fiat/BTC rates (multi-source, BlueWallet-style logic)
portal-macros	Build-time fetch_git_hash! and related macros
portal-cli	Small binaries for manual protocol and integration checks
portal-app-demo	Local Axum demo: multi-session HTTP API over app
portal-rest/clients/ts	TypeScript client
