Bridging ERC-20 Token

Bridging ERC-20 Token from Sepolia (L1) to L2

Visit the rollup bridge at https://testnet-rollup-bridge.altlayer.io and ensure you are on the deposit tab.

We will use the Multi-sequencer test ERC-20 token (MSEQ) as an example. Select the Multi-sequencer test ERC-20 token from the token selector.

Input the number of tokens you would like to bridge to L2. You will be prompted with an "Approve" button if you have an insufficient token allowance. Click the "Approve" button and confirm the transaction on your wallet.

Wait for the increase allowance transaction to be confirmed. The "Deposit" button will appear.

Click the "Deposit" button and confirm the transaction on your wallet.

After a short moment, your deposit will be finalized and you will receive your token on L2.

If you are using metamask, you can click the "Add to Metamask" icon to import the token into your Metamask wallet.
