The Blast bridge moves ETH or stablecoins from Ethereum to Blast, normally crediting deposits within minutes of Ethereum confirmation. Blast announced a wind-down on 2 October 2026, so the decisive question is whether you still need assets on a closing network. If you still need to bridge ETH to Blast, the [Blast bridge](https://blastbridge.org) transfers it from Ethereum. * Deposits normally take minutes after the Ethereum transaction confirms. * ETH arrives as ETH; a supported stablecoin deposit may arrive as USDB. * Blast has asked users to withdraw to Ethereum during its wind-down. ### What Does the Transfer Do, and What Will I Receive? The Blast bridge sends an asset from Ethereum mainnet to Blast, an Ethereum layer 2 network. Your wallet submits a transaction on Ethereum; bridge contracts then pass a message that credits your balance on Blast. The two balances live on different networks, even when your wallet shows the same account address for both. ETH deposits are intended to become usable ETH on Blast, including for transaction fees there. Blast was designed so ETH and its stablecoin USDB could earn native yield through balances that rebase, or increase when yield is paid. A supported stablecoin deposit can therefore leave you holding USDB rather than the same token you sent. That yield design is no longer a reason to assume a return. Blast’s current description displays 0% for both ETH and stablecoins, while its 2 October announcement asks users to move assets back to Ethereum. Check what asset you will receive and whether you need it on Blast before signing a deposit. ### How Do I Bridge ETH From Ethereum to Blast? To move ETH, you need ETH in a wallet you control on Ethereum mainnet, enough extra ETH for Ethereum gas, and a reason to use the balance on Blast. Gas is the network charge for processing a transaction. An exchange balance is not the same as ETH already in your own wallet. 1. Connect your wallet and check that Ethereum is the source network and Blast is the destination. 2. Choose ETH and enter an amount that leaves enough ETH in the wallet to pay Ethereum gas. 3. Check the destination account, estimated amount and network charge before approving the transaction. 4. Save the Ethereum transaction hash, then wait for confirmation and the credit on Blast. A small first transfer can show whether the route and destination account are the ones you intended. Sending the rest later means paying Ethereum gas again, so weigh that extra cost against the value of checking first. Once credited, view the balance with your wallet set to Blast rather than Ethereum. ### Can I Bridge USDC From Ethereum to Blast? You can bridge USDC to Blast if the route you are using currently accepts it, but check the asset shown for delivery: it may be USDB, Blast’s stablecoin, rather than USDC. Those names are not interchangeable. If you specifically need USDC for another task, receiving USDB changes what you can do next. USDC is a token, so a transfer may require an approval transaction before the deposit transaction. Approval lets the bridge contract spend the amount you authorize; it does not itself move the funds. Both transactions can require Ethereum gas, paid in ETH rather than USDC. For example, depositing 100 USDC does not guarantee a balance of exactly 100 USDC on Blast. The quoted destination asset could be USDB, and any conversion terms shown before signing determine the amount received. Keep some ETH available on Blast for later transactions; a stablecoin balance alone cannot pay Blast’s ETH gas charge. ### What Wallet Do I Need? You need a self-custody wallet that can use Ethereum mainnet and Blast mainnet and sign transactions on both. The wallet should let you switch networks while keeping control of the same account. Blast mainnet’s chain ID is 81457, and ETH is its gas currency, according to Blast’s network information. Check the network name and chain ID before treating a missing balance as a failed transfer. A wallet displaying Ethereum will not show an ETH balance credited on Blast in its Ethereum balance. If you deposit a stablecoin, you may also need to display USDB as a token in the wallet to see it. ### How Long Does It Take, and What Does It Cost? An Ethereum-to-Blast deposit normally reaches Blast within minutes after its Ethereum transaction confirms, though network congestion or a delayed cross-network message can extend that. Blast bridge fees and time depend chiefly on Ethereum gas for the deposit, any token approval, and whether the route converts the asset. Review the amount and charges shown before signing because gas changes with demand. * ETH deposit: an Ethereum transaction fee, paid in ETH. * USDC deposit: potentially a separate approval fee plus the deposit fee, both paid in ETH. * Later use or exit: Blast gas for transactions there, and Ethereum gas for any required final claim. As an illustration, if a deposit used 120,000 gas at 10 gwei per gas, its Ethereum network charge would be 0.0012 ETH. Depositing 0.1 ETH under those assumptions would require at least 0.1012 ETH in the wallet. This is arithmetic for planning, not a live quote or a fixed bridge fee. The return trip now has a more important clock. Blast said withdrawals would pause while it unwinds assets held through Lido, a process expected to take about a week from its 2 October announcement. It plans to reopen withdrawals with a 24-hour delay and keep its normal withdrawal interface available until 26 October 2026; after that, it says withdrawals will require direct use of its Ethereum bridge contracts. The announced 24-hour delay does not make funds withdrawable during the pause. ### How Do I Check a Pending Transfer? Check a pending deposit by starting with the transaction hash your wallet recorded on Ethereum. Look it up in an Ethereum block explorer: a failed transaction means the deposit did not complete, while a confirmed one means the Ethereum step succeeded. Then check the same wallet account on Blast for the credited ETH or, for a stablecoin route, USDB. If Ethereum shows success but Blast does not yet show the balance, allow time for the cross-network message and check that your wallet is on Blast mainnet. Do not send a second deposit merely because the destination balance has not appeared. The source transaction hash is the concrete record to keep while investigating a delay. For a withdrawal, “pending” can mean something different: the exit may be in its required waiting period or withdrawals may still be paused under Blast’s wind-down plan. Check Blast’s current announcement and the withdrawal status before attempting another transaction. A completed wait may still require a final Ethereum transaction and its gas charge before the funds appear in your Ethereum wallet. * Confirm the source network, destination network and asset you will receive. * Keep ETH for gas and save the transaction hash. * Check the wind-down timetable before depositing or planning an exit. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://aboutcryptotalks.gitbook.io/aboutcrypto/how-long-does-the-blast-bridge-take-from-ethereum.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
