Frequently Asked Questions
Paste any address or connect your wallet. We check 287 defunct contracts for unclaimed balances. If found, click Withdraw — the transaction goes directly from the original contract to your wallet.
Yes. Fully open source. No proxy contracts, no intermediaries. Most withdrawals are simple ETH transfers with no approvals needed. A few contracts (e.g. wrapped ETH variants, dividend tokens) require a token burn or two-step process — the UI explains each case. Every withdrawal can be done manually on Etherscan — this site just makes it easier.
DeBank, Zerion, and Zapper only index active protocols. These contracts are defunct or too obscure to be tracked. Your ETH is still onchain, it just doesn't show up in standard wallet interfaces.
No. Completely free. After a successful claim, there's an optional donation prompt — entirely voluntary.
287 contracts across defunct DEXes (EtherDelta, IDEX v1, Token.Store), dividend tokens (PoWH3D, Fomo3D), NFT auctions (MoonCatRescue, DADA), bounty platforms, ICO escrows, ENS old registrar deeds, DAO treasury refunds (DigixDAO), and wrapped ETH variants.
You don't need this site to claim. Every withdrawal can be done directly on Etherscan: go to the contract, click "Write Contract", connect your wallet, call the withdraw function. We simply facilitate the crafting of withdrawal transactions on your behalf — each contract's address and function is shown in the claim details. Our code is open source for anyone to audit.
