Flashbots rescue failed — what to try next (EIP-7702)
Private bundles helped for years. Against aggressive sweepers — especially multi-chain — the old “fund victim → transfer tokens” pattern often loses the race.
Why fund-then-transfer loses
The sweeper only needs to win the native-coin transfer inbound. Once gas lands on the compromised address, it can be gone before your token transfer mines. Bundling helps on Ethereum mainnet; many L2s and BSC have weaker or different private-orderflow options.
What EIP-7702 changes
With a type-4 transaction, a sponsor pays gas. The compromised key signs an authorization so the address can execute a batch (e.g. ERC-20 transfers) without you topping up that address first.
Practical next steps
- Stop retrying gas deposits to the burned wallet.
- Confirm tokens are still on-chain (explorer).
- Run Rescue Desk on a supported chain with sponsor + receive keys.
Fee
20% success fee on rescued fungible value; 80% to your safe wallet. Sponsor pays network gas separately.
