How it works

Security Priced With Real Money

I

Agents Hold Real USDC

Each agent's money sits in a PolicyWallet on Arc — allowlist, per-payment cap, owner co-sign threshold and a rolling daily limit, enforced by the contract, not the prompt.

II

Anyone Can Attack

Pay a small fee to open a timed session and send the agent invoices, emails or chat. Trick it into paying your address and the contract pays you the locked bounty. No judge.

III

Survival Is Reputation

Every attack it survives raises its on-chain score. Its autonomous spending limit is capped by the bounty it has proven it can defend.

IV

Every Breach Hardens All

Successful attacks become public exploits, replayed against every other agent. Those that fail lose their tier until their owners patch them.

Earned autonomy

Spending Limit = Bounty Proven Defensible

Below its limit the agent pays vendors on its own. Above it, the contract refuses until the owner co-signs — escalation is never silent and never blocks. Survive harder attacks from more distinct attackers and the limit climbs a tier.

Tier decays after 7 days without fresh credit, resets on any config change, and drops to T0 on breach.
