Circle's Agent Stack lets agents pay each other. Aegis answers what happens when a paid agent underdelivers — providers post a USDC bond, buyers attach low-cost SLA coverage to each job, and verified breaches pay out automatically.
Connect your wallet on Arc Testnet and run the full flow yourself — post a bond, open coverage, close it. You'll need free testnet USDC from the Circle Faucet.
Deposit USDC as a bond. Max coverage = bond × 10.
Pick a provider below (or paste an address) and open coverage.
Bonded providers you can buy coverage from.
When one agent pays another for a service — an API call, a data feed, an inference — and the provider fails to deliver to spec, there's no native, objective, on-chain way to make the buyer whole or to price reliability. Today that means blind trust, off-chain reputation in walled gardens, or slow human disputes — none of which scale to thousands of autonomous transactions a day.
Five simple steps turn a provider's promise into collateral-backed, enforceable coverage — settled entirely in USDC.
A provider deposits a USDC bond. Max live coverage = bond × leverage, so every commitment is collateral-backed.
A buyer opens low-cost SLA coverage on a job and pays a small premium. The service payment itself rides x402 / Nanopayments.
Objective SLA outcomes — uptime, response-integrity, latency — are attested, with an optimistic challenge window an arbiter can veto.
A verified breach pays out automatically — from the provider's bond, straight to the buyer, in USDC.
An on-chain score lets buyers price-discriminate and lets the protocol tune leverage and premiums over time.
Never a speculative token. Bonds, premiums, and payouts all settle in the asset Arc is built on.
Value flows through Aegis on every job — in USDC.

Premium flows to the pool. The provider's reputation rises. The buyer keeps the result.
Verified in the challenge window, then paid automatically from the bond. Reputation falls.
Bonds, premiums and payouts settle in USDC — Arc's native gas and unit of account. No volatile collateral.
Arc + Circle's Agent Stack make autonomous, sub-cent agent-to-agent payments real. Aegis adds the missing trust layer.
Arc's public testnet is live and mainnet is approaching. Infrastructure built now ships as the agent economy forms.
Payments, wallets and identity are being built. Objective insurance, underwriting and recourse are largely unaddressed.
These numbers are read straight from the chain — updating as people test the protocol.
Contracts, risk model, prototype — and now live on Arc testnet.
