How to bridge to Blast

• An EVM wallet such as MetaMask or Rabby, with your seed phrase stored offline.
• ETH on Ethereum mainnet: the amount you want to bridge plus some for the L1 gas fee.
• Stablecoins, if you want to receive USDB.

Most wallets add Blast automatically when you connect to a Blast dapp. To add it manually, use these settings:

Network name

Blast

RPC URL

https://rpc.blast.io

Chain ID

81457

Currency symbol

ETH

Block explorer

https://blastscan.io

1. 1

   Open the official Blast app

   Go to blast.io and check the address bar before doing anything else. Bookmark the official site so you never land on a look-alike.

2. 2

   Connect your wallet

   Connect MetaMask, Rabby or another EVM wallet. Make sure it holds enough ETH on Ethereum mainnet to pay the L1 gas fee for the deposit.

3. 3

   Choose the asset and amount

   Select ETH, or a supported stablecoin which arrives on Blast as USDB. Enter the amount you want to bridge and review the estimated result.

4. 4

   Confirm the deposit

   Approve the token if your wallet asks for it, then confirm the deposit transaction. Read every wallet prompt before signing.

5. 5

   Switch to the Blast network

   After the deposit lands, switch your wallet to Blast. Your ETH or USDB balance appears and starts rebasing automatically, no staking required.

To move funds back, open the Withdraw tab in the official app, pick the asset and confirm. Because Blast is an optimistic rollup, native bridge withdrawals pass through a challenge window of several days before you can finalize them on Ethereum.

USDB is redeemed for DAI when it arrives on Ethereum. If you need funds faster, reputable third-party bridges offer quicker exits for a fee.

• Start with a small test amount the first time you bridge.
• Check the transaction on the block explorer before assuming it failed.
• Nobody from support will ever DM you first or ask for your keys.
