On Oct. 2, the native-yield-focused Ethereum layer-2 network Blast announced it is shutting down due to maintenance costs exceeding revenues.
Users have been instructed to transfer their funds back to the Ethereum mainnet by Oct. 26 in order to withdraw via the standard interface.
In its shutdown notice, Blast explained that it lacks a viable path toward long-term economic sustainability. The chain will wind down through a series of asset withdrawals that will temporarily halt users’ ability to exit.
This move arrives nearly three years after Blast announced a $20 million funding round backed by Paradigm and Standard Crypto on Nov. 20, 2023. The project launched its early access phase that same November ahead of a planned mainnet debut in February 2024.
According to its technical documentation, the project functions as an Ethereum-compatible optimistic rollup designed to funnel yields from real-world-asset protocols and ETH staking to its community. Its website highlights MakerDAO and Lido as yield providers and features several additional investors among its backers.
While the model was built to give holders returns generated by these foundational protocols, Blast stated that the underlying operational economics no longer warrant keeping the network active.
Blast’s withdrawal pause and Oct. 26 cutoff
Blast announced that it will initially pull its assets out of Lido—cited in its architecture as a primary source of ETH staking yield—a procedure anticipated to take about a week.
Throughout this unwinding phase, user withdrawals will be paused temporarily, even after the platform trims its withdrawal delay period to 24 hours.
The announcement notes that withdrawals will become available again under the shortened 24-hour delay once the Lido asset retrieval finishes. The week-long pause and the subsequent withdrawal delay are distinct elements of the exit schedule.
The directive to migrate funds back to Ethereum covers balances stored within the Blast web application, referred to in the notice as the PWA. All participants were urged by Blast to complete their withdrawals prior to Oct. 26.
Following that deadline, assets will still be retrievable, though users will have to interact directly with the project’s bridge contracts on the Ethereum mainnet.
Blast stated it will release comprehensive guidelines for that alternative method ahead of the deadline. While the notice provides an estimated timeframe for the Lido asset unwind, it omits a precise date for the resumption of standard withdrawals.
