Blast, the Ethereum layer 2 that once held $2.3 billion in total value locked, is shutting down after its daily chain revenue fell to roughly $110, the team announced on October 2. The operator said the network now costs more to run than it earns and sees no credible path back to profitability.

Users have until October 26 to withdraw funds through Blast's standard interface. After that deadline, remaining holders must interact directly with Blast's bridge contracts on Ethereum mainnet — a slower and riskier process. According to Decrypt, roughly $51 million remains bridged into Blast's contracts, including $46.6 million in staked ETH held with Lido. Blast must first unwind that Lido position, a process expected to take about a week, before the standard seven-day withdrawal window can shorten toward 24 hours.

Who controls the bridge?

Unchained reported that five keyholders control Blast's bridge contracts, and any three of them can alter the contracts or pause withdrawals outright. The chain's fraud-proof system — the mechanism designed to let anyone challenge an invalid transaction record — reportedly never fully functioned, leaving open the possibility that a malicious proposer could finalize a bad state. These trust assumptions did not trigger the shutdown, but they compound the operational risk for users still exiting the network.

How did Blast get here?

Founder Tieshun Roquerre, known as Pacman and the creator of NFT marketplace Blur, opened deposits in November 2023, months before the chain existed. Users deposited ETH and stablecoins into a points-accruing contract with withdrawals locked until mainnet launched on February 29, 2024. Total value locked hit $230 million within 48 hours of the unveiling, crossed $720 million by early December 2023, and reached $2.27 billion by launch, per CoinDesk — making Blast one of the largest L2s in the Ethereum ecosystem almost overnight, built largely on the promise of a token airdrop.

The BLAST token launched in June 2024, and the farming capital left soon after. CoinDesk reported that as of Friday, DeFi applications on Blast held about $32 million in TVL — a decline of nearly 99% from the February 2024 peak. The token fell another 19% on the shutdown news and now trades roughly 98% below its launch price. Blast's core pitch of native yield on deposited ETH and stablecoins attracted capital that had no reason to stay once the airdrop concluded, leaving sequencer and infrastructure costs with no usage base to cover them.

Is Blast an outlier?

No. Research from Yellow and BlockEden.xyz on the 2026 Ethereum L2 sector, based on Dune Analytics data, found that the top three networks by TVL — Base, Arbitrum and Optimism — now capture roughly 80% of all sequencer fee revenue across tracked chains. Starknet's zkLend and the L2 project Kinto both shut down in 2025 after exploits and funding problems. The Block's 2026 Layer-2 Outlook flagged most mid-tier rollups as unlikely to survive the next twelve months.

For Blast's remaining users, the operative deadline is October 26. Anyone holding assets on the chain after that date faces direct interaction with bridge contracts on Ethereum mainnet, subject to the multi-week unwind of the Lido position and the governance risk of a five-keyholder multisig.
