Blast bridge has canonical, liquidity, and routed options for moving assets to Blast. They differ in how transfers settle, how quickly funds arrive, and which token you receive. Blast announced on 2 October 2026 that it is winding down, so anyone considering an inbound transfer now needs a reason to use the funds and a plan to withdraw them.

What Does the Blast bridge Do?

A bridge moves value between Ethereum mainnet and Blast, an Ethereum layer 2 network. On the canonical route, an Ethereum deposit enters bridge contracts and is credited on Blast after the deposit message is processed. A liquidity bridge instead pays out from funds already available on the destination chain and settles its position separately.

The token received matters as much as the amount. ETH deposited through a qualifying route arrives as ETH on Blast, while a supported stablecoin deposit can arrive as USDB, Blast’s native stablecoin. Blast was designed so ETH and USDB balances could earn native yield through rebasing, meaning the balance increases rather than paying a separate reward token. The rate varies; Blast’s published site currently shows 0% for both.

The wind-down changes the practical decision. Blast has asked users to withdraw to Ethereum, including balances in its app. It says withdrawals will pause for roughly a week while it exits Lido positions, then resume with a 24-hour delay. The normal withdrawal interface is due to remain available until 26 October 2026; after that, Blast says withdrawals will require direct interaction with its Ethereum bridge contracts.

Which Type of Route Fits the Transfer?

The main distinction is who supplies the destination funds and what asset the route delivers. For a deposit needed by one specific app, check the app’s required token first: “dollars on Blast” may mean USDB or USDC, and those are different assets.

• Canonical bridge — Best for an Ethereum-to-Blast deposit when its delivered token matches the app’s requirement. It uses Blast’s bridge contracts; it does not fit a time-sensitive exit, especially during the announced withdrawal pause.
• Liquidity bridge — Best when destination funds are needed quickly or a particular token must arrive. A provider supplies liquidity and charges for it; it does not fit if the quoted receive amount or available liquidity is inadequate.
• Route aggregator — Best for comparing available bridge and swap paths in one quote. Its result may use a liquidity bridge underneath, so the displayed destination token and minimum received matter more than the route label. It does not create an available path when providers have stopped serving Blast.
• Exchange withdrawal — Useful only when an exchange currently offers a withdrawal directly to Blast in the token the app accepts. It does not help someone whose funds are already in an Ethereum wallet, and exchange network support can change during a wind-down.

These are routes, not interchangeable versions of the same transfer. A common mistake is bridging USDC and assuming the app will receive USDC: a canonical stablecoin route may credit USDB instead. Fix that by reading the receive asset in the quote, then matching it to the token named by the app.

What Will It Cost and How Long Will It Take?

An Ethereum to Blast bridge deposit requires an Ethereum transaction, so its gas cost depends on network demand and the transaction’s gas use. For scale, a transaction using 150,000 gas at 10 gwei costs 0.0015 ETH; that is an illustrative calculation, not a live quote. A liquidity route can also reduce the amount received through a provider fee or swap price, so compare its quoted output with the amount sent.

Deposits commonly appear after Ethereum confirmation and processing on Blast, often within minutes, but a quote is the useful timing estimate for a particular route. The return trip is different: the canonical withdrawal delay is the period before funds can be claimed on Ethereum. Blast’s announced 24-hour delay applies only after the Lido exit and withdrawal pause are complete, so check the current withdrawal status before starting an exit.

How Do You Make the Transfer Your App Needs?

Start with the app’s exact network and token requirement, then choose a route that delivers both. If you need stablecoins for an app transaction, also allow for a small ETH balance on Blast to pay gas; a wallet holding only USDB or USDC cannot pay that gas.

1. Confirm that the app still operates on Blast and identify the token it accepts.
2. Check the current deposit or withdrawal status against Blast’s wind-down announcement.
3. Compare routes by destination token, quoted amount received, total cost, and expected arrival time.
