Recover ETH stuck in old smart contracts
Thousands of ETH sit forgotten in defunct contracts from the 2015–2019 era.
DeBank, Zapper, and other portfolio trackers don't detect them.
Velix.AI's December 2017 ICO via the OpenZeppelin RefundableCrowdsale pattern. The sale missed its 5,000 ETH soft cap (raised ~4,900 ETH), the owner finalized into refund mode, and most depositors clawed back over the following months. 81 ETH still sits in the RefundVault waiting for the long tail of stragglers. Single-tx claim: call claimRefund() on the crowdsale, which delegates to the vault and returns your original deposit.
