Step 2: Enter the cross-chain bridge. The system defaults to the interface for cross-chaining from the HECO  to the ETH. Fill in the recipient address on the Ethereum (ERC20)  and the amount of MDX to be cross-chained. Ensure that your wallet has HT for the transaction fee. After authorization, click 'Next' to confirm. It may take a few minutes for the Ethereum to receive the funds, so please be patient.

Step 2: Go to the cross-chain bridge. The system defaults to the interface for cross-chaining from BNB Chain to the ETH. Enter the Ethereum (ERC20) receiving address and the amount of MDX to be cross-chained. Make sure you have BNB in your wallet to cover the transaction fee. After authorization, click Next to confirm. It may take a few minutes for the Ethereum to process the transaction, so please be patient.
