This is a POC for an Anchor SDK generated by Robots 🤖. Not for use in a production setting.

Stellar Connect

TypeScript monorepo for Stellar anchor infrastructure. Build compliant anchor services and client integrations with minimal boilerplate.

Packages

Package	Description	Docs
@stellarconnect/anchor	Anchor server framework — SEP-1, SEP-6, SEP-10, SEP-24	README
@stellarconnect/sdk	Client SDK — discovery, auth, deposits, withdrawals, polling	README
@stellarconnect/core	Core primitives — Signer, NetworkClient, TomlDiscovery, XDR	README
@stellarconnect/signers	Signer utilities — keypairSigner, callbackSigner	README

Quick Start

Stand up a SEP-compliant anchor server in ~40 lines:

pnpm add @stellarconnect/anchor
pnpm add express cors @stellar/stellar-sdk   # peer dependencies

import express from 'express';
import cors from 'cors';
import { AnchorServer } from '@stellarconnect/anchor';

const anchor = new AnchorServer({
  secretKey: process.env.STELLAR_SIGNING_KEY!,
  jwtSecret: process.env.JWT_SECRET!,
  domain: 'localhost:8000',
  network: 'testnet',
  assets: {
    native: {
      deposit: { enabled: true, minAmount: 1, maxAmount: 10000 },
      withdraw: { enabled: true, minAmount: 1, maxAmount: 10000 },
    },
  },
});

const app = express();
app.use(cors({ origin: '*' }));
app.use(express.json());

app.use(anchor.toml()); // SEP-1: /.well-known/stellar.toml
app.use('/auth', anchor.sep10()); // SEP-10: Web Authentication
app.use('/sep24', anchor.sep24({ interactive: { url: 'http://localhost:8000/interactive-flow' } })); // SEP-24
app.use('/', anchor.sep24({ interactive: { url: 'http://localhost:8000/interactive-flow' } })); // SEP-24 pages

app.listen(8000, () => console.log('Anchor running on http://localhost:8000'));

See the example anchor server for a working reference.

Compliance Testing

Validate your anchor against the official Stellar Anchor Tests suite:

# Start the example server
cd examples/anchor-server
STELLAR_SIGNING_KEY=SBRVW5MTD2FGEQMYG77CAB5LYDVVNY7UOUOC2WUGPLUMRB5VJ27MSL2K \
JWT_SECRET=test-secret-key-minimum-32-characters-required-for-security \
PORT=8000 node dist/index.js

# Run compliance tests (in another terminal)
docker run --network host stellar/anchor-tests:latest \
  --home-domain http://localhost:8000 --seps 1 10 24

Expected: 55/55 tests pass.

• anchor depends on core — server-side framework
• sdk depends on core — client-side SDK
• signers depends on core — signer implementations
• core has no internal dependencies — foundational primitives

Tech Stack

• TypeScript 5.3+ (ESM only)
• Express 4.x (anchor peer dependency)
• @stellar/stellar-sdk ^12.0.0
• Vitest (testing)
• pnpm workspaces (monorepo)
