Blast Shuts Ethereum Layer 2 With $6.51M Left in Bridge

A One-Year Window to Reclaim Funds

Blast switched off its Ethereum (ETH) layer-2 network on Nov. 4 and, in the same move, opened a recovery website where users can reclaim funds the chain still holds. Claims stay open for one year, through Nov. 4, 2027, the date the team named as the final day of support. ETH, wrapped ETH or USDB sitting in a Blast wallet, held in a pending withdrawal, or stored in the Blast Mobile app can all be recovered through the site. Blast set out the process in a shutdown notice posted on X, saying the recovery website would stay active for 12 months. Claims settle directly out of recovery smart contracts on Ethereum's layer 1 blockchain protocol, so payouts do not depend on Blast keeping any infrastructure alive. A user starts by searching for an address that held ETH, wrapped ETH or USDB on Blast. The search also works when a separate wallet is approved to claim for that address, which covers the owner of a Safe or another smart wallet. Blast Mobile addresses do not exist on Ethereum (ETH), which makes those claims different. A Mobile user claims with the seed phrase from the app, imports it into a wallet such as MetaMask or Rabby, and connects; that wallet displays a different address from the one the app showed. This is the step where care matters most, and anyone unsure of the mechanics can review how to recover a crypto wallet before typing anything anywhere. The recovery page warns users to enter a seed phrase only into a wallet app, “never into a website,” and the discipline that protects a ledger recovery key applies here. A seed phrase typed into a fraudulent site hands over every wallet it controls. The site went live the same day the network went dark, so no gap opened in which balances sat unreachable.

Bridge Balances Fell 84% in a Week

Blast set the exit in motion on Oct. 2 with a wind-down announcement that spelled out the reasoning. The team wrote that it had launched the chain with the goal of building a self-sustaining network for users and developers, but no longer saw any credible way to keep the chain's economics working, because the cost of running Blast “outstripped the revenue generated by the L2.” The exit followed a fixed sequence. Blast first pulled its assets out of Lido, a process it expected to take about a week, and froze withdrawals while that ran. Once the unwind finished, the team cut the withdrawal delay to 24 hours and set Oct. 26 as the last day for withdrawals through the standard Blast interface. Assets stayed reachable after that date, but only through the Blast bridge contracts on Ethereum (ETH). On-chain data shows where users stood by that deadline. The canonical bridge on Ethereum held about $41.04 million on Oct. 26, the day the standard interface closed. It then fell to about $6.59 million on Oct. 31 from about $36.63 million a day earlier, a one-day drop of roughly $30 million, and stood at about $6.51 million as of Nov. 3. That is roughly 84% of the bridge value gone inside a week, with the Oct. 30 to Oct. 31 slide its sharpest single move. The figure counts what remains in the bridge, not what users have already recovered, so the total paid out through claims could be higher. The DeFi-focused chain Katana said on Oct. 26 it had snapshotted Blast users and wallet activity, promised extra boosts for wallets active on its own network, and repeated that commitment on Nov. 4. On markets, Coinbase's trading suspension, set against an Oct. 26 deadline, took the BLAST price off a major venue as the wind-down advanced.

No Credible Economic Path

The Nov. 4 notice and the Oct. 2 statement frame what is left. Because the recovery contracts pay from Ethereum itself, the 12-month window holds even with the layer 2 gone. USDB, the chain's stablecoin, redeems through those contracts, without the mechanism risk tied to algorithmic stablecoins. The bridge numbers suggest most holders did not wait, since roughly 84% of the value left before the claims page opened. The seed-phrase step for Blast Mobile users is the remaining weak point. BLAST once surged 256% to top Upbit's daily gainers board, but the recovery window, not trading, now defines the asset. Blast's own words stand: the chain was built to sustain users and developers, and the team judged the economics could no longer support it.
