WithdrawalVault
What is WithdrawalVault
A simple contract that accumulates partial and full withdrawals that comes from the Beacon Chain. Its address corresponds to the type-0x01 Lido withdrawal credentials. During the accounting oracle report, the vault is emptied by Lido to the internal buffer; see Lido contract docs for details.
The vault is recoverable, so any ERC-20 and ERC-721 tokens can be transferred to the treasury by DAO.
The currently deployed version is upgradable because of anticipated Ethereum withdrawal mechanics changes.
The contract is meant to be ossified somewhere after withdrawal credentials triggerable exits are implemented.
