Blast L2 Shuts Down, Sets November 2027 Claim Deadline

Ethereum Layer 2 network Blast has officially shut down, giving users until November 4, 2027, to recover remaining funds after its developers concluded that operating costs had made the blockchain financially unsustainable. The closure, confirmed on November 4, follows a month-long wind-down that began in October, when Blast acknowledged that maintaining its infrastructure cost more than the revenue generated by the network. Remaining ETH, wrapped ETH (WETH), USDB and eligible pending withdrawals can now be recovered through Blast's official recovery portal, which processes claims directly through smart contracts on Ethereum mainnet.
