Recover ETH stuck in old smart contracts

Vesper vETH Pool

Vesper Finance opened its vETH pool in December 2020: depositors put in ETH, received vETH shares, and the pool lent the ETH out through yield strategies. In July 2022 the pool's holdings were moved into a newer Vesper pool that it still draws on, and since May 2026 that ETH has been sitting idle rather than being lent. Every vETH share still represents a proportional part of it.

Frequently Asked Questions
Paste any address or connect your wallet. We check 388 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.
