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.
DigitizeCoin (DTZ) ran a 2018 presale built on the OpenZeppelin RefundableCrowdsale template. The contract uses a 3-arg TokenPurchase event variant (PallyCoin family) but the refund flow is canonical. Soft cap missed and the contract finalized into refund mode; ~1.1 ETH still sits in the sibling RefundVault. Standard claimRefund() returns your deposit.
