Keep your wallet.
Add a gate.

Your agent asks to pay or trade. You approve with your face. A contract verifies your signature on-chain and spends from an allowance you set. Nothing leaves your wallet until then.

The model

Three addresses. Money and permission never share one.

Your wallet

Keeps every asset. Grants the gate an allowance per token, and a list of contracts an agent may use. Signs setup, never a transfer.

Your face

A biometric scan in the YID app signs the exact transfer or trade. That signature is the only thing the gate trusts.

The agent

A gas wallet. It proposes and submits what you approved, byte for byte. Use ours, or run your own.

One transfer

Four steps. Five seconds. Transfers and trades.

1
Agent asks
A transfer, or a call to a contract you allowed: a swap, a deposit. The gate simulates it first.
2
Phone rings
You see what you send and what you receive. Nothing hidden in a hash.
3
You scan
Your biometric key signs the decision. Reject is final.
4
Gate executes
Signature verified on-chain, nonce burned, the asset moves or the trade runs. Leftovers come back to you. Replays fail.

Even if

Nobody in the loop can spend. Not even us.

Every party you might assume you have to trust, and what happens when they turn on you.

For agents

Four MCP tools.
Zero custody.

One URL and your Yanez key. Works in Claude, Cursor, or any MCP client. The agent holds no wallet key, and the model never sees the approval receipt.

We pay gas and submit. You run nothing. The gate adds a 0.1% service fee, fixed at deploy and shown on your phone, only when our relayer is the one submitting.
