# Step-by-Step Guide

Dear community members, we are happy to present our simple guide on how to perform cross-chain CLS token transfers between the Ethereum and Binance Smart Chain Network through our native bridge. This bridge is a vital part of our plan to offer CLS on the BSC network, and anyone seeking to bring their Ethereum based CLS tokens should follow the steps below.

**1.** Go to our bridges webpage [https://coldstack.io/bridge/](https://coldstack.io/bridge/).

**2.** Click "Unlock Wallet":

**3.** Make sure your wallet is connected to the correct network - you can click this “Add network” to add the BSC network to your MetaMask wallet, and “Add CLS to you Metamask token list” if you don’t yet have CLS listed in your wallet:

**4.** Select the networks that you wanna transfer tokens between, and the amount of tokens you would like to transfer - minimum for transferring from Ethereum to BSC is 10 CLS tokens, and 25 CLS if transferring from BSC to Ethereum. And then click “Next”.

**8.** Switch networks to the destination network to check if the transaction went through.

After completing these steps, you should have your desired amount of CLS transferred to the network of your choice.
