# Blast Reaches Withdrawal Interface Cutoff With $40M Left in Bridge

Users must now rely on contract-level exits requiring cryptographic proofs and a one-day waiting period to retrieve remaining funds.

## At a glance

- **What happened:** Blast reached its withdrawal interface cutoff deadline while approximately $40 million remained held in its bridge contracts.
- **Why it matters:** Bridge depositors must now conduct technical, manual smart contract interactions requiring cryptographic proofs to recover their assets.
- **Who is affected:** Depositors with assets remaining in the Blast bridge, particularly USDB and native asset holders.
- **What's next:** No next step announced.

## Key points

- Blast reached the cutoff deadline for its standard withdrawal interface with roughly $40 million left in the bridge.
- Contract-level withdrawals require users to submit proofs and wait through a one-day delay period.
- USDB stablecoin holders face an additional secondary claim step to redeem underlying DAI.

## Editorial remark

- **Context:** Blast set interface deadlines to phase out legacy front-end bridge operations, directing remaining depositors toward native contract mechanisms.
- **Impact:** Depositors representing $40 million in bridged capital must interact directly with smart contracts, increasing technical friction and execution complexity.
- **Watch:** Bridge balance reductions and contract settlement activity as users submit manual cryptographic exit transactions.

Ethereum layer-2 network Blast has reached the deadline for its withdrawal interface while roughly $40 million remains deposited in its bridge contracts [1]. The milestone shifts the asset retrieval process away from standard front-end web interfaces to direct smart contract executions [1].

To accommodate the transition, Blast released technical contract-level exit guides for depositors seeking to recover remaining capital [1]. Executing withdrawals directly through the bridge contracts requires users to generate cryptographic proofs and observe a mandatory one-day waiting period before funds become accessible on layer 1 [1]. Depositors holding the network's native stablecoin, $USDB, must also execute an additional distinct claim process to redeem MakerDAO's $DAI [1].

## Manual Exits and Contract Dependencies

The interface deadline places operational burdens directly on remaining bridge depositors [1]. Standard users navigating smart contract interactions without a graphical user interface face heightened execution complexity, as each withdrawal phase mandates precise cryptographic verification against bridge state data [1].

For holders of the USDB stablecoin, the redemption route adds structural steps [1]. Because native bridge mechanics link USDB conversions back to underlying reserve assets, liquidating back into DAI requires the separate secondary interaction after the initial waiting period concludes [1].

At the time of writing, the broader digital asset market traded flat, with $ETH hovering at $2,335 and total market capitalization standing at $2.64 trillion.

## FAQ

**Can users still withdraw funds from the Blast bridge?**

Yes. While the standard web interface has reached its deadline, users can execute manual exits directly through the smart contracts using technical guides provided by Blast.

**What is required to complete a manual withdrawal?**

Contract-level withdrawals require submitting cryptographic proofs and completing a one-day waiting period. USDB holders must also submit an additional claim for DAI.
