Blast, the Ethereum layer-2 network that once held roughly $2 billion in on-chain assets, is shutting down after total value locked on the network fell by 98%, according to the project's announcement reported by Futu Niuniu.

The closure marks one of the largest layer-2 wind-downs since Ethereum's rollup-centric roadmap took hold. Blast launched in early 2024 with a native yield model that paid returns on deposited ETH and stablecoins, a design that helped it climb quickly into the top tier of L2 networks by total value locked. At its peak, on-chain records tracked the network's deposits at approximately $2 billion.

What does the shutdown mean for users?

Assets on the network have since collapsed by 98% from that high-water mark, the report states. The drawdown reflects both outflows following Blast's airdrop in mid-2024 and a broader migration of liquidity toward larger general-purpose rollups such as Base and Arbitrum.

For remaining users, the immediate operational question is the bridge-out window. Layer-2 shutdowns typically proceed through a sequenced wind-down: the operator announces a final date for deposits, freezes sequencer activity, and directs users to withdraw funds through the canonical bridge to Ethereum mainnet. Blast has not yet published a full technical decommissioning schedule in the reported announcement, and users holding assets on the network should monitor official channels for withdrawal deadlines before sequencer infrastructure goes offline.

Why did a $2 billion network fail to retain assets?

Blast's growth model relied on deposit incentives rather than sustained application activity. The project attracted capital through a points campaign that preceded its June 2024 token generation event, and much of that capital treated the network as a short-duration yield venue rather than a settlement layer for durable applications.

Once the airdrop concluded, the incentive-aligned liquidity left. Total value locked fell steadily through late 2024 and 2025, and the reported 98% decline ultimately left the network below the threshold needed to justify continued operator spending on sequencers, provers and business development.

The failure carries a lesson for the L2 market's structure. Roughly dozens of Ethereum rollups launched between 2023 and 2025, but transaction volume and liquidity have concentrated in a handful of networks with distribution advantages. Blast's shutdown demonstrates that a multi-billion-dollar deposit base does not guarantee a viable long-term business when the deposits are rented through incentives rather than earned through usage.

What happens next?

Blast's exit reduces the number of major Ethereum layer-2 networks by one and will likely intensify pressure on other mid-tier rollups that continue to operate with declining asset bases and negative operator economics. Users and teams building on Blast should plan for the bridge-out window and confirm final withdrawal deadlines as the shutdown schedule is published.
