Celer Payment Channels

Celer was a state-channel protocol for off-chain micropayments, launched in 2019. CelerWallet is the on-chain vault; CelerLedger is the user entry point that enforces channel accounting. Celer pivoted to cBridge in 2021 and took the official CelerPay UI offline, but the contracts remained live and unpaused. Users who opened channels and never cooperatively settled can still recover their deposits via the unilateral path: intendWithdraw starts a 10,000-block (~1.4 day) dispute window; after the window any tx sender can confirm and the ETH returns to the depositor.

Frequently Asked Questions

How does it work? ▼

Paste any address or connect your wallet. We check 265 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? ▼

265 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.
