Blast's official withdrawal interface expired on October 26, leaving approximately $40.4 million in assets still sitting in its cross-chain bridge. Users must now interact directly with Blast's Ethereum-based bridge contract to withdraw funds, a process that requires submitting cryptographic proof and waiting one day. USDB withdrawals additionally require separately claiming DAI. The deadline follows Blast's early-October announcement that it would gradually shut down the network after operating costs exceeded its L2 revenue. The team had advised users to move assets to Ethereum mainnet before the October 26 cutoff. Blast has published a contract-level withdrawal guide for remaining users.
