HONG

HONG is a 2016 token-creation contract with a built-in ICO refund path. The verified source keeps each contributor's original ETH in an internal weiGiven ledger and exposes refundMyIcoInvestment(), which returns that tracked deposit while the fund remains unlocked. Forgotten ETH uses event reconstruction plus a live token-holder filter because the weiGiven mapping is not public and the contract also requires the caller to still hold HONG units.

Frequently Asked Questions

How does it work? ▼

Paste any address or connect your wallet. We check 256 defunct contracts for unclaimed balances. If found, click Withdraw — the transaction goes directly from the original contract to your wallet.

Is this safe? ▼

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.

Why can't my portfolio tracker see these? ▼

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.

Do you charge fees? ▼

No. Completely free. After a successful claim, there's an optional donation prompt — entirely voluntary.

What contracts are tracked? ▼

256 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.

Don't trust, verify ▼

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.
