On November 4, 2026, Blast officially shut down its Ethereum layer-2 network and launched a recovery portal for users with remaining funds. The claims window will remain open for 12 months, ending on November 4, 2027. According to the team, payouts are handled through recovery smart contracts on Ethereum mainnet, covering ETH or USD left in a Blast wallet, pending withdrawals, or Blast Mobile balances.
The recovery site allows users to search for addresses that held ETH, wrapped ETH, or USDB on Blast. It also supports approved claim wallets such as Safe or other smart contract wallets. Blast Mobile users, whose addresses do not exist on Ethereum, must import their seed phrase into a wallet like MetaMask or Rabby and connect to the recovery page. The team warned users never to enter a seed phrase into a website.
The shutdown follows an October 2 wind-down announcement in which Blast said 'the economics of operating the chain no longer make sense.' Maintenance costs exceeded revenue generated by the layer-2. The project removed assets from Lido, temporarily froze withdrawals, reduced the withdrawal delay to 24 hours, and set October 26 as the final day for normal interface withdrawals. After that date, assets could still be withdrawn via Blast bridge contracts on Ethereum.
Data from DeFiLlama shows the canonical bridge held roughly $6.51 million on November 3, down from about $41.04 million on October 26, meaning around 84% of bridge funds had already left. The bridge value fell from about $36.63 million on October 30 to roughly $6.59 million on October 31.
Katana, a DeFi-focused blockchain, said it took a snapshot of Blast users and wallet activity on October 26 and repeated that snapshot confirmation on November 4. The broader layer-2 sector also saw shifts: Arbitrum One recorded its most active day since July 18, 2024 on October 28 with 1,087,999 daily active addresses, while Polygon PoS led tracked chains with 1,634,452 active addresses and Base followed with 1,457,258.
