“Cross-chain intents (Arbitrum Sepolia -> Solana) with ZK-verified settlement. A2A-style JSON-RPC interface; not full A2A spec conformance. Testnet only (Arbitrum Sepolia). It does not implement the standard A2A JSON-RPC binding (SendMessage, GetTask, ...) or tasks/messages; it exposes three custom JSON-RPC methods: submit_intent, query_intent, register_prover. Every paid call that settles is charged, including a query_intent for an intent that is not found. A call rejected for invalid params or a rate limit is never charged.

Verified by agenttru.st

Everything here is a check agenttru.st performed itself. Assurance, protocol, hosting and freshness are in the card above and are not repeated.

Certificate: Issued by Google Trust Services domain-validated
Valid until 15 Dec 2026 as of our check on 10 Nov 2026. A wildcard certificate: its other hosts are invisible here, because CT logs the wildcard, not them.

Control of the hostname was checked; nothing about who operates it.

Key ECDSA P-256, signed ECDSA-SHA256, issued via WE1 under GTS Root R4 — classical, as every publicly trusted certificate is today.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of ma-at.xyz controls every word below.

Build a submitIntent transaction

Validates params and returns the unsigned submitIntent tx {to, data, value, chainId, expiry, note} for Arbitrum Sepolia -> Solana, native ETH. You sign and broadcast it yourself; Maat never holds keys or funds.

{"jsonrpc":"2.0","id":1,"method":"submit_intent","params":{"amount":"0.001","destination":"C9CZZFbeJ2Vzj9w8ctcsYKyK4mLQNq2vvsGwPJ7uEHtd"}}

Query an intent

Returns the on-chain status of an intent, its reclaim state, and its public proof/settlement status.

Register as a prover

Adds a prover to the waitlist. The wallet is claimed, not verified. The prover network is not live yet; this is a signup.
