If you got drained, in the past, it's usually been "over." Besides lost funds, unclaimed airdrops, NFT allowlist spots, and rare tokens are still sitting in a wallet you can never safely touch again. But now, with EIP-7702 + tools like Antidrain there is a fighting chance👇 ~~ Analysis by @wmpeaster ~~ EIP-7702 as a rescue primitive Here, cue in EIP-7702. EIP-7702 introduced a transaction type that lets regular Ethereum Virtual Machine (EVM) wallets temporarily behave like advanced smart contract wallets. Notably, this design offers a rescue path for partially recovering assets from compromised wallets. With EIP-7702, you can: ➢ Use a separate sponsor wallet to pay gas ➢ Delegate the compromised wallet to a batch contract ➢ Have that batch contract execute a claim + transfer on behalf of the compromised address ➢ Then revoke the delegation This way, since the compromised wallet isn't directly sending the transaction (it's only authorizing once via EIP-7702), you can slip past sweeper bots and evacuate tokens that would otherwise be unrecoverable. The Antidrain example This sort of recovery flow is exactly the thrust of Antidrain, an EIP-7702 rescue tool built by @Zun2025 and released earlier this year. It's positioned as a last-resort, client-side recovery app for things like airdrops and NFTs. For instance, one user, @0xMoei, said on X this week that they used Antidrain to save their Fwog NFT allowlist spot, successfully minting it and transferring it to a safe wallet after a private key compromise. It's a non-trivial recovery, considering how Fwogs are currently trading around ~$700 on OpenSea. This tool builds EIP-7702 delegations and batch transactions locally in your browser (i.e. no backend server, no key transmission), allowing you to execute rescue operations across supported EVM chains. All that said, this is one of those "break glass in case of emergency" tools. Crucially, Antidrain does ask for the private key of the compromised wallet during setup. Under normal circumstances that's an instant hard "no." Here, the idea is: ➢ The key is already compromised, so the attacker has it anyway ➢ You're just using it one last time to claw back anything that's still recoverable ➢ The tool's design is entirely local, building and signing transactions in your browser To be clear, pasting a private key into a website is virtually always a terrible idea. This avenue is meant only for already compromised wallets as a last ditch resort to bypass squatting sweepers. Hypothetically, if Antidrain were malicious, the worst-case scenarios would be losing whatever remains in your compromised wallet or having your sponsor gas or rescued tokens redirected to an address you don't control. None of your uncompromised wallets would be at risk. The bottom line is that if your wallet is compromised and you're facing a sweeper bot, a tool like Antidrain may be worth a shot. If your wallet isn't compromised, you should never consider pasting your private key into any web app. Use at your own risk, then, and only for wallets that are already burned. The configuration process on the site appears straightforward: ➢ Create and fund your sponsor wallet ➢ Input your desired wallet configurations ➢ Set your rescue details and receiver address ➢ Press "Execute All Wallets" to fire off your batch transaction ➢ Withdraw any remaining gas from your sponsor wallet This system works best for one-shot rescue flows, like "claim this airdrop and send it straight to my safe wallet." A 20% service fee is charged on any ERC-20s rescued for ongoing development. A tool in this vein won't magically expel an attacker from your wallet, but it is interesting to see EIP-7702's potential in giving drainer victims a fighting chance. On a dark day, it could be the difference between salvaging something and losing everything, so keep this capability in mind going forward.
