Blast bridge deposits usually take minutes, but Blast is winding down. Withdrawals are temporarily paused, and Blast plans a 24-hour delay when they resume. The Blast bridge moves your ETH and stablecoins from Ethereum to Blast, but Blast has asked users to withdraw by 26 October 2026.
The Bridge Moves Funds Between Ethereum and Blast
A bridge moves value between Ethereum and Blast, a layer 2 network built to handle transactions outside Ethereum’s main network. You use your own wallet to make the transfer. Unlike an exchange withdrawal, there is no exchange account holding the balance at either end.
For an ETH deposit, a bridge contract receives ETH on Ethereum and a matching balance becomes available on Blast. A contract is a program that carries out rules recorded on a blockchain. This is why sending ETH to a Blast wallet address while your wallet is still on Ethereum is not the same as bridging it.
The asset you receive can have a different name. Supported stablecoins, which aim to hold a value near $1, can arrive as USDB. USDB is Blast’s own dollar-pegged token. Blast says it can be redeemed for DAI when bridging back to Ethereum, so check the expected return asset before you deposit.
Blast was designed to pay native yield: an eligible ETH or USDB balance can grow without a separate deposit into a lending app. That yield is variable, and the bridge itself does not promise a return. Blast’s About page currently displays 0% for ETH and stablecoins, which matters more than an old advertised rate.
A Wallet Deposit Has Two On-Chain Stages
A deposit starts with a transaction on Ethereum and finishes when Blast credits your wallet. Imagine Maya has $300 of DAI on an exchange and wants to use it on Blast. She first withdraws DAI to her own wallet over Ethereum, keeping some ETH there to pay transaction fees.
Before using an Ethereum to Blast bridge, Maya checks that DAI is accepted and that the destination is her wallet on Blast. She also checks the asset she will receive. A familiar stablecoin name on Ethereum does not mean the same token will appear on Blast.
For a stablecoin, the wallet may first ask for an approval. That gives the bridge contract permission to use a stated amount of the token. Maya then signs the deposit transaction; once Ethereum confirms it, a message tells Blast to credit her USDB. An ETH deposit normally skips the token approval.
Maya must also plan for gas on Blast. Gas is the network fee paid to make a transaction, and Blast uses ETH for it. If she bridges only DAI and receives only USDB, she may have funds on Blast but no ETH to move them. A small ETH balance on Blast solves that practical problem.
Ethereum Gas Sets Much of the Cost
The main deposit cost is Ethereum gas, which changes with network demand and the work a transaction requires. Wallets usually show an estimate before you sign. A stablecoin approval, if needed, is a separate transaction with its own gas cost.
For scale, say a transaction uses 100,000 gas at 10 gwei per unit. Gwei is one billionth of an ETH, so that example costs 0.001 ETH. It is an illustration, not a current bridge quote: both the gas used and its price can differ when Maya signs.
After Ethereum confirms the deposit, the balance typically appears on Blast within minutes. Heavy traffic or delayed bridge processing can extend that time. If it has not arrived, Maya should check the Ethereum transaction first, then check the same wallet on Blast before trying another deposit.
The Wind-Down Changes the Return Trip
The return trip is currently the deciding factor. In its 2 October 2026 announcement, Blast said it would close the network and asked users to withdraw to Ethereum. It temporarily paused withdrawals while it retrieves staked ETH, a process it expected to take about a week.
Blast said withdrawals would resume with a 24-hour delay. That delay starts after withdrawals reopen; it does not mean a withdrawal begun today will finish tomorrow. The earlier, roughly seven-day withdrawal period is therefore a poor guide to the current exit schedule.
A withdrawal also has more than one stage. The user starts it on Blast, waits for the required delay, then completes the claim on Ethereum. Blast’s bridge documentation describes that final claim, which needs ETH on Ethereum for gas. Funds have not reached an Ethereum wallet merely because the first step succeeded.
Blast says its usual withdrawal interface will be available until 26 October 2026. After that, it expects users to withdraw by interacting directly with bridge contracts on Ethereum and says it will publish instructions. Anyone holding funds on Blast should follow the current withdrawal notice before signing a transaction.
The Next Step Depends on Where Your Funds Are
For someone still on Ethereum, I would avoid a new deposit for yield while Blast is winding down. The route may move funds in minutes, but it leaves you with a separate exit to complete. For someone already on Blast, the useful task is to prepare that exit and check when withdrawals reopen.
- Check whether you hold ETH or a stablecoin, and what asset the bridge would deliver.
- Allow ETH for gas on the network where you need to sign a transaction.
- If your funds are on Blast, follow Blast’s current withdrawal timetable and complete the Ethereum claim.
