Blast sets Oct. 26 interface deadline as integrators plan exits

Blast said on Oct. 2 that it would wind down its Ethereum L2, citing operating costs above revenue, and set Oct. 26 as the deadline for withdrawals through its normal interface. Integrators need to map user balances and prepare an exit path around the bridge’s staged withdrawal process.

What does the Blast bridge shutdown notice say?

Blast said withdrawals would pause for about a week while it withdrew its Lido assets, then resume with a 24-hour delay. The team said assets would remain withdrawable after Oct. 26, but users would need to interact directly with Blast bridge contracts on Ethereum; detailed instructions were still to come.

Integrators documenting how users entered the chain should use blast bridge for the Ethereum-to-Blast ETH or stablecoin transfer. That records the inbound leg, while withdrawals during the shutdown follow Blast’s own bridge process.

What should integrators do before Oct. 26?

Integrators should identify which user assets are held on Blast, how their application accounts for those balances, and which actions require the application’s contracts. The shutdown notice sets a withdrawal timeline; it does not explain what happens to every application or position.

• List assets and positions users hold through the application, including balances that may not appear as simple wallet holdings.
• Stop directing users to deposit into Blast and update any deposit instructions the integrator controls.
• Tell users when the announced pause begins and when the standard withdrawal interface is due to close.
• Prepare to update withdrawal guidance when Blast publishes its contract instructions.

These steps separate the user’s asset exit from the application’s own shutdown work. A withdrawal can return tokens to Ethereum without moving application records or recreating a position there.

How should users handle withdrawals after the interface closes?

Users should follow Blast’s published instructions for direct contract withdrawals after Oct. 26, rather than relying on an integrator’s unverified contract address or message. The announced route is through contracts on Ethereum, but the team had not yet published the detailed steps in its notice.

For integrators, the practical plan is to inventory positions, stop new deposits, communicate the pause and deadline, then revise the exit guide when Blast releases its instructions. The next milestone is the end of the Lido asset withdrawal and the restart of withdrawals with the announced 24-hour delay.
