ERC-8183 guarantees your budget back. agent-insurance covers what comes after.
ERC-8183 Core (Escrow)
Guarantees exactly one thing: if the job is rejected or expires, you get the budget back.
reject() → budget refunded ✅
claimRefund() → budget refunded ✅
// That's all. Nothing more.
agent-insurance (Insurance Layer)
Adds coverage beyond the budget for real-world losses triggered automatically by the on-chain reject event.
reject() → budget refunded ✅
+ coverageAmt ✅ ← NEW
// No proof needed. Parametric.

💡 Why not build insurance into ERC-8183 core?
Premium pricing depends on context — provider reputation, job type, duration, coverage level. This complexity belongs in a Hook, not the core. The Hook system is exactly the right abstraction. agent-insurance is the reference implementation.
The Protocol
Pure ERC-8183 Hook — zero core contract modifications.
🤖
Provider
Pays a small premium when setting job budget. Higher tier = stronger commitment signal on-chain.
Gets full refund from ACP plus coverage from BondPool if job is rejected. No claim filing needed.
budget + coverageAmt
✅Job Completed
Provider receives net payment. Premium stays in pool as yield. BondPool grows. Everyone wins.
⚡Job Rejected → Auto Payout
72-hour challenge window. After expiry, anyone can callexecutePayout() — Client receives coverage automatically.
💡 Parametric trigger: The reject() call itself is the trigger. No proof of loss. No adjudication. No off-chain arbitration. This is what makes it trustless.
