About USDC Copilot

An AI portfolio agent for autonomous USDC treasuries. Built for the Agora Agents Hackathon, May 2026.

What it is

USDC Copilot is the cockpit autonomous AI agents need to operate USDC treasuries across multiple chains. It reads the unified balance via Circle Gateway, indexes every USDC Transfer on Arc + 3 EVM testnets, scores each watched transfer for risk with Claude Haiku 4.5, and lets Claude Sonnet 4.6 propose concrete, executable rebalancing actions. One click sends those actions through CCTP V2 — Fast Transfer, sub-15-second end-to-end on testnet.

Circle products

Circle Gateway

Unified USDC balance across chains

Powers the Balance page. POST /v1/balances against gateway-api-testnet.circle.com.

CCTP V2

Real cross-chain USDC transfer

Burn on source → Iris attestation → mint on dest. Same contract addresses across all EVM testnets.

Developer-Controlled Wallets

Signer abstraction

Available as an alternate execution backend; production deployments without raw private keys.

Arc

Settlement chain

USDC-native gas, sub-second finality, the Copilot's preferred destination for idle reserves.

Paymaster

USDC-paid gas

Featured on the Balance page for Arbitrum Sepolia (EIP-2612 permit + ERC-4337).
