Withdrawal metadata is represented in padded form on Ethereum to simplify processing, and compact form on Fuel. The ID of a withdrawal is the hash of the padded-form withdrawal metadata.
A withdrawal registry keep track of whether a withdrawal has been processed or not (a Boolean value), indexed by the rollup block height and unique withdrawal ID. "Processed" withdrawals are completed withdrawals (i.e. the tokens have been withdrawn from the contract).
