Blast to Wind Down Ethereum L2 as Costs Outpace Revenue

Users are being urged by Blast—formerly positioned among Ethereum’s premier layer-2 networks by total value locked—to migrate their funds back to the mainnet prior to the upcoming shutdown.

The closure of Ethereum layer-2 network Blast has been initiated after its operating costs outstripped the revenue generated by the chain.

Through a Friday statement published on X, the network was declared economically unviable by Blast due to an absence of any credible path forward, prompting the platform to urge users to withdraw their holdings back to the Ethereum mainnet.

“We launched Blast with the goal of building a self-sustaining chain for users and developers,” the team said. “Unfortunately, the economics of operating the chain no longer make sense.”

The network will reduce its withdrawal delay to 24 hours, although withdrawals will be temporarily suspended while Blast unwinds its Lido assets—a procedure anticipated to require roughly a week.

An interface provided by Blast remains available for user withdrawals until October 26, after which those funds will still be kept accessible, though recovering them will mandate that individuals interact directly with the underlying bridge contracts deployed on Ethereum.

Guidance for withdrawing directly via the bridge contracts will be published by Blast prior to the October 26 deadline, alongside an earnest plea for participants to transfer their holdings to the Ethereum mainnet beforehand.

Blast Grew Out of Blur’s NFT Boom#

The establishment of Blast was undertaken by Tieshun “Pacman” Roquerre—the creator behind the NFT marketplace Blur, which debuted in October 2022 and rapidly challenged OpenSea by courting professional traders using token incentives—while Blur had already surpassed OpenSea in trading volume by late 2022 and widened that advantage in early 2023, propelled partially by its token airdrop and reward mechanisms.

In November 2023, Blast was revealed to the public by Roquerre, featuring native yield on Ether and stablecoins alongside a points system linked to an expected token airdrop—a strategic approach that successfully attracted over $2 billion in deposits prior to the launch of its mainnet in February 2024.

Growth across the Blast ecosystem proved challenging to sustain during a wider contraction within the NFT sector, as statistics from DeFiLlama demonstrate that its decentralized finance total value locked has experienced a continuous slide since reaching a peak of approximately $2.2 billion in June 2024, plummeting by over 98% recorded since that time.

A comparable contraction has been experienced by Blur, whose total value locked—surging past $200 million during its early 2024 apex—currently rests at approximately $27 million.
