## Runtime

* Node.js 22 or newer
* Express 5
* ethers 6
* Static browser client with optional Privy integration
* Local encrypted storage with optional ciphertext-only IPFS pinning

## Start locally

```powershell theme={null}
npm ci
npm test
npm run dev:networks
```

This starts the mainnet-configured application at `http://localhost:4020` and the isolated testnet application at `http://localhost:4021`.

<Warning>
  Use testnet and low-value test accounts while integrating. The test suite uses mocked providers and is not a substitute for live end-to-end validation.
