The Paradigm-backed network said the cost of running the chain now exceeds what it earns, and DefiLlama puts its remaining deposits at $32.14 million against $124 of fees a day. Withdrawals through Blast's own interface close on October 26.
Blast said on Friday that it will wind down the Ethereum layer-2 network it launched in 2024, and gave anyone still holding assets on the chain until October 26 to withdraw them through its own interface.
The project put the decision in cost terms in a post on its X account. "We launched Blast with the goal of building a self-sustaining chain for users and developers," it said. "Unfortunately, the economics of operating the chain no longer make sense." It added that "the ongoing costs of maintaining Blast exceed the revenue generated by the L2, and we do not see a credible path to making the chain economically sustainable."
Third-party data tracks the same collapse. DefiLlama put the value locked on Blast at $32.14 million on Friday afternoon, with $124 of chain fees over the preceding 24 hours, of which $110 counted as revenue. CoinDesk reported that the chain earned $1,793 across the whole of September, against a monthly peak of roughly $3.5 million in June 2024.
At $110 a day, the chain would bring in about $40,000 over a year. Blast has not published what it costs to run, so the gap it describes cannot be sized from outside the company, but the revenue side of that gap is a matter of public record.
Blast raised $20 million in November 2023 in a round led by Paradigm and Standard Crypto, according to The Block, and drew about 200,000 users into an early-access phase that credited points for deposits before the chain itself was live. CoinDesk put those pre-launch deposits at $1.1 billion and the chain's eventual peak at $2.2 billion of value locked in June 2024. Measured against DefiLlama's current reading, that is a fall of about 98.5%.
Getting out will not be a single step for everyone. The Defiant reported that withdrawals will pause for roughly a week while Lido positions are unwound, then resume with a 24-hour delay, and that about $63.5 million still sits in Blast's canonical bridge on Ethereum. That the chain has to unstake before it can finish paying people out is a consequence of how its deposits were held rather than a dispute about who owns what.
The bridge balance and DefiLlama's $32.14 million are not the same measurement. The first is what the layer-1 contracts hold on the chain's behalf; the second is what is deployed inside applications running on Blast. Neither figure is a count of how many people have yet to act.
After October 26 the interface stops processing withdrawals and users have to interact with the bridge contracts directly, which means constructing transactions against those contracts instead of using a web front end. The Defiant reported that contract-level withdrawals continue past the deadline, so assets are not stranded, but retrieving them stops being a front-end operation and starts requiring a degree of technical confidence that casual holders of small balances may not have.
BLAST fell 17% on Friday to a market value of about $23 million, The Block reported. CoinDesk put the token roughly 98% below where it launched.
Blast arrived in a crowded field of general-purpose layer-2 networks competing for the same deposits, and the ones holding up best are attached to a business that already has customers. Coinbase's Base and Robinhood's Ethereum layer-2 both sit beside an existing brokerage or exchange, and Base is still spending on the roadmap: it is shipping its own account abstraction standard ahead of Ethereum's after merger talks failed. Even for those chains the fee side is thin. Robinhood's chain saw network fees fall 95% from their peak over twelve days last month, while the value held in applications on it rose. The difference is that a brokerage can carry a layer-2 that does not pay for itself. Switching a chain off is not unprecedented either: BounceBit killed its own layer-1 in August after deciding that maintaining a fork of a discontinued software stack would cost more than moving its token to a chain someone else already runs.
The announcement did not address what happens to the BLAST token once the chain stops, or what becomes of any remaining treasury, according to The Block. For anyone with a balance the operative detail is narrower: Blast's interface handles withdrawals until October 26, and after that the bridge contracts do.
