Connect your wallet.

Select From: Ethereum Testnet (Sepolia) → To: LinkLayer Testnet (77162).

Enter the amount of ETH you want to deposit.

Click Bridge/Deposit and confirm the transaction in Metamask.

4. Wait for Confirmation
Your transaction will first appear on the Ethereum testnet explorer.

After a short time, the funds will show up on the LinkLayer Testnet explorer:

5. (Optional) Withdraw Back to L1
If you want to move ETH back from L2 to L1, use the Withdraw option in the bridge UI.
