Blast, an Ethereum Layer 2 backed by Paradigm, said Friday that it is shutting down its network and telling users to move assets back to Ethereum by October 26. The project said the cost of operating the chain had risen above the income it generates.

The closure puts fresh attention on the economics of smaller rollups in a crowded Layer 2 market. While lower infrastructure costs have helped the sector, Blast’s decision highlights that reduced expenses alone may not be enough if user activity and revenue remain limited.

Rapid rise followed by steep decline

Blast launched in November 2023 after raising $20 million in a funding round led by Paradigm and Standard Crypto. Before its February 2024 mainnet debut, it had attracted more than $2 billion in deposits from nearly 200,000 early users, aided by native yield on ETH and stablecoins.

That early momentum has faded sharply. DeFiLlama now puts Blast’s DeFi total value locked at about $32 million, while L2BEAT lists roughly $38 million secured on the platform and notes that the project’s fraud-proof system remains under development.

Market pressure also showed up in the token. According to The Block, BLAST fell 17% on Friday, leaving the token with a market value of about $23 million.

Revenue did not keep pace with costs

The project pointed to a basic imbalance in its business model: the network was not bringing in enough money to justify ongoing operations. DeFiLlama recently showed around $755,500 in annualized fees on Blast, but only about $22,700 in annualized chain revenue.

That gap underscores a broader issue for smaller rollups. Attracting deposits or initial interest is not the same as sustaining enough regular transactions to cover the continuing cost of running a network.

Lower data costs were not enough

Blast operated after Ethereum had already introduced blobs through EIP-4844, a change designed to reduce a major cost for rollups by letting them post data more cheaply than with traditional calldata.

Those savings appear not to have solved the larger problem. Blob data is temporary and is removed from nodes after roughly 18 days, which helps reduce costs, but Blast’s shutdown suggests that cheaper data availability by itself does not create the level of network activity needed to make a rollup sustainable.

Part of a broader market shakeout

Blast’s closure comes amid wider retrenchment across the blockchain sector. The source article notes that three blockchain projects halted operations on the same day in May, and that more than 99 blockchain projects shut down in the first half of 2026.

It also says rollup value locked has fallen about 36% from its peak of more than $50 billion in October 2025. At the same time, Arbitrum One, Base, and OP Mainnet are estimated to account for nearly 75% of overall activity, reinforcing how concentrated the Layer 2 market has become.

What users need to know next

Following the announcement, South Korean exchanges Upbit and Bithumb flagged BLAST as a trading-caution asset. Blast said it will first unwind its Lido holdings, a process expected to take about a week.

Users can withdraw through Blast’s interface until October 26. After that date, withdrawals will still be possible, but users will need to interact directly with Blast’s Ethereum bridge contracts.

With DeFi TVL now around $32 million, the shutdown is not presented as a major market risk. The more significant takeaway is the test it poses for Layer 2 business models, especially for smaller networks trying to survive on limited activity and thin revenue.
