Blast, the Ethereum Layer 2 network backed by venture firm Paradigm, will wind down its operations after running costs outstripped the revenue the network generates, The Block reported.

The decision marks one of the most prominent rollup closures since the broader expansion of Ethereum scaling networks began in 2023–2024. Blast launched with significant backing from Paradigm, one of the most active investors in crypto infrastructure, and attracted attention for its yield-bearing design, which passed rewards from ether and stablecoin holdings back to users on the base layer.

According to the report, the economics of running the network no longer justified continuing. Costs associated with operating the chain — including sequencer infrastructure, data publication, and ongoing engineering — exceeded the fees and revenue the network produced. That imbalance, sustained over time, drove the decision to wind the network down rather than continue subsidizing operations.

The closure carries operational consequences for the network's users and the broader Layer 2 sector. Users holding assets on Blast will need to bridge funds back to Ethereum mainnet or another destination before the network ceases operation, and developers who deployed contracts on the chain will face migration decisions. The Block's report identifies the cost-revenue gap as the proximate cause, a dynamic that has pressured smaller rollups as competition among Layer 2s has intensified and fee income has compressed.

Blast's trajectory from a heavily funded launch to a wind-down illustrates the structural challenge facing Ethereum rollups that lack sustained transaction demand: fixed operating costs, particularly the cost of publishing data and maintaining sequencer infrastructure, do not scale down proportionally when activity declines. Networks that once commanded meaningful fee revenue during high-activity periods can fall below break-even when usage drops, leaving backers and operators to absorb ongoing losses.

For Paradigm, the wind-down represents a notable outcome for a portfolio company in the infrastructure segment the firm has invested in heavily. The firm was an early backer of Blast and has funded numerous other scaling and trading infrastructure projects across the Ethereum ecosystem.

The development also arrives amid a broader market-structure shift in the Layer 2 sector. Dozens of rollups and validiums now compete for the same transaction flow, and the economics of running a chain have deteriorated as fees have fallen and activity has consolidated around the largest networks. Smaller operators face a narrowing path to sustainability, and Blast will not be the last to confront that arithmetic if current conditions persist.

A timeline for the wind-down, including deadlines for users to bridge assets off the network, is expected to accompany the formal shutdown process. Users with funds or deployed contracts on Blast should monitor official channels for those dates.
