Delegate
One transaction of type 4 points your address at the Leash contract. Your address now holds this marker as code:
0xef0100...
Undo it any time by delegating somewhere else, or to nothing.

Give your agent a wallet.
Keep the leash.
Leash is a contract your wallet delegates to. You say who your AI agent may pay, how much and until when. The chain refuses everything else.
The leash
What you gave the agent. Change a rule and the counters start over, like on the chain.

This session
The rulebook, knotted on the leash
Seven rules. That is all the leash is made of.
How it is wired
Your wallet, with a rulebook bolted on.
EIP-7702 lets an ordinary wallet run a contract's code for as long as its owner wants. Leash is that code. You keep your key and your address. The agent gets its own key and its own gas, and can only act through the rules.

Set a policy
You call your own address once, with the agent, the limits and the call list. In the same transaction as step 1 if you like. This is the real calldata of the policy on the left:

The agent works
The agent signs transactions with its own key and sends batches to your address. Each call is checked against the policy first, then made as you. One refusal cancels the whole batch.
// agent -> your address
execute([ { target, value, data }, ... ])

Straight talk
What it guarantees, and what it does not.
The leash holds
- An agent can only call what the policy lists, send only what the limits allow, and pay only who you named.
- An agent can never make the account call itself: the admin functions stay yours.
- A refused call cancels the whole batch. Nothing half-happens.
- Pause, revoke and expiry stop the agent at once. Replacing a policy restarts its counters.
- No owner but you, no upgrade, no fee.
What it cannot do
- Approvals you gave before Leash are outside the policy. If a router already holds an unlimited approval and the agent may call it, the agent can pull through it. Revoke old approvals first.
- Limits are ceilings, not judgement. An agent can still spend its whole allowance on things you listed.
- Periods are fixed windows: a burst at the end of one and the start of the next can reach twice the cap.
- Not audited and not deployed. Nothing here holds funds today.
FAQ
The honest answers.
Is the page above real?
Yes. The errands go through the same rules engine the contract's tests are checked against, and the button runs your whole session on Robinhood Chain itself with a code override, so the contract that is not yet deployed runs on the real chain's state. No funds exist and nothing is sent.
Do I lose control of my wallet?
No. Your key still works as before and can do anything. Leash only gives the agent a narrow door. You can pause it, revoke it or undelegate in one transaction.
What stops the agent from editing its own rules?
Only a call from your account to itself can change the policy, and the agent cannot make that call: the contract refuses any call from the agent to your own address. A contract the agent is allowed to call cannot do it either, because it would be the caller, not your account.
Is it live?
No. The contract is written, compiled and tested, not audited and not deployed. The read-only checks against Robinhood Chain confirm there is no code at its future address yet.
Do I need $LEASH?
No. The contract has no token and no fee. See the token page.
