Capabilities

What it does

One MCP endpoint takes an agent from “what do I hold?” to a transaction ready to sign, with every step checked.

Read

Every position an address holds across Sui protocols, protocol data, token prices, wallet balances, transaction history and live swap quotes.

Build

Unsigned transactions for swaps through the Astros aggregator, NAVI supply / withdraw / borrow / repay, reward claims, vault deposits and Volo liquid staking.

Preview & sign

Each build is simulated on chain, checked against risk rules (health factor, price impact, third-party builders) and summarised by AI on a preview page where the user signs.

Wallet registry

Register the addresses your agent may act for, with the provider that signs for each one, so it always knows which wallet to build for and how that wallet signs.

  3. 3

    Review the dry-run and AI summary, then sign with your wallet or a passkey. The agent follows it with defi_get_tx_status.

Signing

Wallets that can sign

The service builds; a wallet you pick signs. Register an address with defi_wallet_add and its provider, and every transaction for it comes with the right signing steps.

Guarantees

What it never does

Never signs

Builders return unsigned bytes. Nothing is broadcast unless you, or a signer you chose, approves it.

Never touches a key

Private keys stay in your wallet, your passkey authenticator or your signer. The service never sees one.

Stores only addresses

The only thing kept per client is the list of wallet addresses you choose to register.

Anonymous by design

Each client gets an anonymous identity. No account, no email, no profile.
