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.
Avastars was an NFT project (2020) that allowed users to mint generative avatar NFTs. Users deposited ETH into the minting contract as a prepayment balance, which was drawn down as they minted. The project is defunct since September 2021, but the minting contract still holds unspent deposit balances. Users can withdraw their remaining deposits via withdrawDepositorBalance() with no restrictions.
