1. Open the official BenFen Bridge address in your browser: https://www.benpay.com/bridge
2. On the bridge page, select the source chain and the token you need to bridge in.

1. Click [Connect (Source Chain) Wallet].
   1. Note: For web-based operations, you must first install the wallet extension for the corresponding source chain in your browser.
2. Then, click [Connect Benfen Mainnet Wallet] and log in to your BenPay wallet using one of the three available methods:
   1. ZK-Login (Recommended — Create & log in with your Google or Apple ID)

1. After successfully connecting both wallets, if this is your first time performing a bridge-in operation for this token, first click the Approve Token button and complete the cross-chain approval for the token according to your wallet's prompts.
2. After the approval is successful, enter the amount you wish to bridge in.
3. Click [Confirm Trade] and follow the steps in your wallet extension to confirm the transaction.

  • To perform a bridge-in transaction, you only need to have enough of the source chain's native token in your wallet for gas fees.
  • The BenFen Bridge does not charge any additional service fees.

1. After submitting the transaction, you can scroll down on the current page to view the record and status of this and past cross-chain transactions.
2. After waiting for the transaction to be fully confirmed on-chain, you can view the arrived assets on the "Dashboard" in your BenPay wallet.
