Blast shuts down and opens Ethereum recovery through November 2027

Blast confirmed its Layer 2 blockchain has shut down on November 4, 2026, and established a recovery website for users with remaining funds. The operator announced the recovery interface would remain active for 12 months, with a final support date of November 4, 2027. The recovery process covers funds in L2 wallets, pending withdrawals, and Blast Mobile accounts.

Recovery Process Details

The recovery website allows users to enter their Blast wallet address or an approved claimant address to check their eligible assets. The interface automatically includes unfinished withdrawals, meaning users who had started moving funds to Ethereum but hadn't completed the process when the chain closed can still claim their assets.

The recovery interface lists $ETH, $WETH and $USDB as eligible assets that users can withdraw directly from recovery smart contracts on Ethereum mainnet. Unlike the old bridge system, the new recovery process handles wrapped ether differently, including it directly in the claimable assets.

Blast Mobile Recovery

Blast Mobile users face a different recovery process. They must import their Mobile seed phrase into a wallet application like MetaMask or Rabby, then connect that wallet to the recovery site. The resulting address will look different from the original Blast Mobile address, which is normal since the original address doesn't exist on Ethereum.

The recovery page includes explicit security instructions: "Only ever type your seed phrase into your wallet app, never into a website." This reverses previous guidance that warned against importing the Mobile seed phrase into MetaMask, as that belonged to a different address system.

Shutdown Timeline

Blast first announced the wind-down on October 2, 2026, citing that ongoing maintenance costs exceeded L2 revenue and there was no credible path to making the chain economically sustainable. The initial plan gave users until October 26, 2026, to withdraw through the normal Blast interface.

The October plan also included withdrawing Blast's Lido assets, which the team expected to take approximately one week. During that period, withdrawals were temporarily unavailable, then resumed with a reduced 24-hour delay. The November announcement confirms the shutdown and provides the new recovery route, without reopening the October withdrawal window.

Legacy Contract Guides

Blast's old contract withdrawal guides describe different processes than the current recovery system. The ether contract-withdrawal guide explained the Ethereum yield manager and withdrawal queue behind the bridge, with separate stages for initiation, finalization, and receipt of funds. These guides described the old bridge workflows, not the current recovery contracts.

The stablecoin contract guide described $USDB withdrawals paying out as $DAI, where the recipient had to call the yield manager's claim function. Under the old system, multisigs could claim funds, but some deposit-forwarder and sweeper contracts could not. The current recovery page includes unfinished withdrawals in its address lookup and directs claims to recovery contracts on Ethereum.
