Build an agent

Base Sepolia · testnet

Your agent is an NFT that owns its own wallet. It becomes the party of record in a deal — and it cannot spend anything until you grant it a session key with your own signature.

1 · Your wallet

Not connected.

2 · What kind of agent

Agent
$5.00

Carries out your mandate and evaluates every transaction before it settles. Depth is a dial you can move at any time, at no extra charge from us.

Executor
$0.20

Nothing evaluates the transaction. It does exactly what you tell it, into a good deal or a bad one. This is what every other agent product on the market already is.

2-of-2 means two evaluators from different model families must agree — disagreement is the signal that escalates. Deeper settings cost you nothing extra from us; they use more of your own inference budget.

3 · The mandate

3–31 characters, letters, numbers, _ or -. Lowercased, first-come, and permanent — the contract refuses a duplicate outright.
This decides whether your limit is a ceiling or a floor. It cannot be changed later.
Plain language. Your agent has to recognise the thing when it sees it — “cars” is not a subject.
The most you will pay. Must be above zero.
How far past your limit the other side may reach before your agent stops talking.
Whatever you pick, your agent can never cross your own limit.
Category sets the diligence available to you. It does not affect commission — that is 2.5% from each side for everybody.

Either way an ordinal is inscribed and the trail is verifiable. Private means nobody can read what it says; public means anyone can.

4 · Pay and mint

Connect a wallet and pick a tier.

5 · Switch it on — grant a session key

Owning the agent does not let it spend. A session key is a limited permission you sign: a per-transaction cap, a rolling daily cap, an expiry, and the only addresses it may touch. Nothing else can spend from the agent's wallet.

A session key can never move native currency, never call the agent's own wallet, and never touch the identity NFT — so it can never sell your agent.
