Creating cross-chain Transactions

This article will cover how to utilize Beam Bridge to create cross-chain transactions between Ethereum to Beam. This step-by-step tutorial provides a foundation for completing cross-chain transactions with all supported tokens including:

• $ETH, $USDT, $DAI, $WBTC on Ethereum.

• $bETH, $bUSDT, $bDAI, $bWTC on Beam.

Send $ETH from Ethereum to Beam

Once your MetaMask Wallet configuration is complete, it is time to bridge assets from Ethereum to Beam blockchain!

1. Launch the Bridges app from the DApp store in Beam Wallet >>> DApp store >>> Bridges app.

2. Select Ethereum to Beam.

3. Select “bETH (id:36)” from the drop-down currency list and select “AUTOMATIC WAY” prompting a browser pop-up. (Always double-check a token's asset ID. Multiple tokens can have identical names, but their asset IDs always remain unique.)

4. In the browser, connect your MetaMask Wallet. Select "Ethereum to Beam".

5. When bridging tokens other than ETH, users must "approve token" to enable them for cross-chain transfers to Beam (this process only needs to be done once).

6. Enter the transfer amount. Click "transfer".

7. A pop-up will open up in your MetaMask Wallet to "Confirm the transaction". A transaction notification will appear in the browser.

8. When the transaction is complete (it might take a few minutes), your bETH can be withdrawn to your Beam Wallet.

9. Your new balance will also be reflected in your Beam wallet!
