A self-custodial onchain firewall. The instant a verifiable threat hits, it auto-evacuates your funds — at rest in your wallet AND deposited in DeFi — to a vault only you control, inside the reaction window non-atomic hacks leave open. It turns the same EIP-7702 delegation attackers use to drain wallets into your defense. Live end-to-end on Robinhood Chain testnet: full GuardianModule + RulesEngine firewall, 90 tests, real Aave V3 exit fork-verified on Arbitrum One.
The solution. coincoin enforces protection at the account level via EIP-7702. A watcher reads real on-chain threat signals; when one fires inside the window, a bounded keeper exits your DeFi positions (exitAaveV3) and sweeps every token to a SafeVault only you can withdraw from. First tool to cover funds at rest AND in DeFi — Harpie's blind spot. 100% non-custodial (keeper can only send to your own vault; revocable in one tx). A proactive firewall (RulesEngineV1) also reverts malicious approvals before they land.
Live & verifiable. Full GuardianModule + RulesEngineV1 on Robinhood Chain testnet (chain 46630) — 0xd0d301…3b77 / 0xc20A9d…bc52. 90 tests pass (incl. a real Aave V3 fork on Arbitrum One). End-to-end rescue proven on-chain: idle funds and a deposited Aave position pulled to the user's vault, no human in the loop.
