Blast L2 to wind down as costs outpace revenue
Tech & Launches ·
The Ethereum layer-2 network Blast is ceasing operations after concluding its chain can no longer sustain itself financially.
Blast disclosed the shutdown in a statement posted to its official account, saying the expense of running the network has outstripped the income it generates and that no viable route to profitability remains in sight, according to the announcement. The project, which at one point carried a valuation near $2.3 billion as an Ethereum-based L2, is now directing users to move funds off the chain entirely, per Decrypt.
To ease the exit process, Blast is cutting its withdrawal waiting period down to 24 hours from its prior setting. Before that shorter window takes effect, the team must first unwind assets staked through Lido, a process it estimates will take roughly a week; withdrawals will be paused entirely during that stretch. Once the Lido unwind finishes, standard withdrawals resume under the new 24-hour delay.
Users have a hard deadline of October 26, 2026 to pull funds out through Blast's own interface and route them to Ethereum mainnet, including balances sitting in the Blast progressive web app. After that date, withdrawals remain technically possible, but only by interacting directly with Blast's bridge contracts on Ethereum's base layer, with the team promising guidance on that process closer to the cutoff.
The shutdown marks a reversal for a project that previously drew $20 million in backing from Paradigm in 2023, a detail highlighted by WuBlockchain. Blast acknowledged the outcome fell short of its original aim of building a chain that could sustain itself economically for both users and developers, and apologized to those who built on or supported the ecosystem.
What remains unclear is how much of user and developer activity will migrate elsewhere versus simply exit the ecosystem, and whether the roughly year-long runway to the October 2026 deadline will be enough to avoid stranded funds once interface-based withdrawals end. The six-way corroboration across outlets confirms the core facts, but neither the announcement nor related coverage specifies current total value locked on the chain or how many active users remain to be affected.
