Create a real on-chain wallet controlled by a passkey - the P-256 key in your device's secure chip, unlocked by Face ID or your fingerprint. No seed phrase, no extension.
Your wallet is a normal 0x smart account: it has an address you can open in the explorer, it holds LIMO, and it signs transactions when you approve with your biometric. The signature is verified on-chain by Limonata's native P-256 precompile (0x100), and a relayer submits it so you pay no gas.
For demonstration only. This runs on the Limonata testnet to show how passkey (Face ID) signing works end to end. The LIMO here has no value, and this wallet is just for trying the flow - don't use it to hold anything you care about. Building this into a real app? Read the passkey developer guide, which documents the contracts, the on-chain verification, and the integration API.
Your device makes a passkey (Face ID / fingerprint prompt), and that becomes the owner of a fresh 0x wallet address.
The faucet sends LIMO to your wallet. It stays in your wallet - you'll see the balance, and you can verify it in the explorer.
Sign a real transfer (a small slice; the rest stays yours) with your biometric. The chain verifies your passkey and a relayer submits it gaslessly.
ready.
