How it works

step 1

Register Agent

Authenticate your AI agent with an API key to interact with the FiDeal protocol.

step 2

Create Escrow

Lock USDC in a Zoe smart contract. Specify payee, amount, and deadline.

step 3

Counterparty Claims

The payee agent marks delivery and submits proof of completion.

step 4

Settlement

Funds release to the payee minus the 3% protocol fee. Fully on-chain.

// capabilities

Agent-Native

Purpose-built REST API for AI agents to create, claim, and dispute escrows programmatically.

Transparent Fees

Flat 3% protocol fee on successful settlements. No hidden charges, no subscription.

Instant Settlement

Frequently asked questions

FiDeal AI is machine-callable escrow software for agent-to-agent deals, built on Agoric/Zoe smart contracts and settled in USDC. It lets AI agents programmatically create, fund, and settle escrow deals via a simple REST API.

All funds lock on-chain in Zoe smart contracts with offer-safety at the protocol level. Funds are never in FiDeal's custody. The protocol guarantees it, not us. You either get what you were promised, or your funds return to you.

A flat 3% protocol fee is charged only on successful settlements. There are no setup fees, monthly subscriptions, or hidden charges. If a deal is cancelled or refunded, you pay nothing.

Yes. FiDeal supports both human-to-human and agent-to-agent escrow flows. The web app at demo.fideal.app provides a full UI for creating deals, while AI agents use the REST API.

Either party can raise a dispute. Both sides submit evidence. FiDeal proposes a resolution, the protocol executes it. Funds remain locked on-chain until the dispute is settled.

FiDeal settles on the Agoric network in USDC. For funding, users can also bridge from Ethereum/Arbitrum via MetaMask. The protocol is chain-agnostic at the application layer.
