CoinDesk reported on October 2, 2026, that Blast was shutting down its Ethereum-based chain and that users had until October 26 to withdraw through Blast’s interface.
Blast confirmed the move itself a day later, in a post published October 3, saying it would wind down the network and asking users to move their assets to Ethereum mainnet through the normal interface by October 26.
What happened
The core development is simple: Blast is ending operations for its Ethereum layer-2 network and has set a deadline for users to withdraw through the standard interface. Blast attributed the decision to cost — the company said the ongoing costs of maintaining the chain exceed the revenue it generates. CoinDesk, in its reporting, described the network as no longer sustainable once activity declined and operating costs could no longer be covered.
“The ongoing costs of maintaining Blast exceed the revenue generated by the L2.” — Blast
For users, the operational detail that matters most is the October 26 deadline. Blast said users have until that date to withdraw through the normal interface — a cutoff CoinDesk independently confirmed in its reporting.
Context
This is not a routine product adjustment. Blast launched with the goal of running a self-sustaining network, and the shutdown notice marks the conclusion that the economics no longer worked. Both the Blast post and CoinDesk’s reporting frame the move the same way: a response to weakened activity and operating costs the network could no longer support.
The available sources support a narrow factual record. They establish the shutdown decision, Blast’s stated rationale, and the October 26 withdrawal deadline through the interface. They do not lay out a full technical playbook for withdrawals after the deadline, or describe additional operational steps beyond the public request to exit through the normal interface before that date.
Who is affected
The people directly affected are Blast users holding assets on the network, including balances held in the Blast progressive web app (PWA). For them, the practical change is immediate — they need to move assets to Ethereum mainnet before October 26 to use the standard withdrawal path described in the announcement.
For developers and projects built on Blast, this is an operational transition, not just a communications issue. The network they integrated with is being wound down, so any service that depends on Blast’s normal interface will need to account for the deadline — and for whatever withdrawal instructions Blast publishes next.
What to watch next
The date to watch is October 26, 2026 — the deadline Blast set for withdrawals through the normal interface. Before then, the key follow-up is whether Blast publishes the detailed instructions it promised for interacting directly with bridge contracts after that date.
Until then, the confirmed record is limited to the shutdown announcement, Blast’s stated cost rationale, and the October 26 request to withdraw through the standard interface.
