Every payment, trade, and signature shows on your phone in plain words. A biometric scan signs it. A contract verifies your signature on-chain before anything moves. No key to steal, no seed phrase to lose, and an AI agent that can ask but never take.
Both put the same biometric approval between money and anyone who wants to move it. They differ in where the funds live.
Your MetaMask, Ledger, or any wallet stays exactly as it is. You grant a gate contract an allowance per asset and a list of contracts it may use. An AI agent can then pay or trade within those limits, one scan per action, and never touches your keys.
A smart contract account of your own, on Base, with an address you can receive to before it even exists. No seed phrase, no private key anywhere. Dapps connect through WalletConnect, agents through MCP, and every request shows you what you send and what you receive before you scan.
The YID app derives a BLS key from your biometrics at scan time. It signs the exact terms you saw. Our contracts verify that signature on-chain with the BLS precompiles that shipped in Ethereum's Pectra upgrade and on Base with Isthmus.
An agent, a dapp, or you. The request becomes an intent: what moves, where, and a hash the contract will hold it to.
The terms reach the YID app in words: recipient, amount, what you receive. Nothing hidden in a hash.
Your biometric key, at the assurance tier the scan reached, signs the terms. Reject is final.
Signature against your registered key, the hash of exactly this intent, a nonce that cannot repeat. Then it executes.
| Party | Can | Cannot |
|---|---|---|
| You | approve or reject each request; set allowances, pause, add devices; revoke anything with one transaction | be impersonated: the contract holds your keys, and nothing else signs like them |
| An agent | propose transfers, trades, contract calls; submit what you approved | alter it, reuse it, approve anything, or touch a key that spends |
| Our servers | ask you, simulate, submit approved operations, pay gas | spend. Compromised, they can ring your phone and waste gas |
| Yanez | deliver requests, attest the scan, sign a receipt | forge your approval: the contract checks your signature, not theirs |
| The contracts | verify, count, execute exactly what you signed | be administered or upgraded; there is no owner role |
Gate the wallet you already trust, or carry one that never had a key.
