# Swaps

*Railway supports swapping from both 0x and 0zk addresses through Railway DEX. Easily swap any ERC-20 through the* [*0x API*](https://www.0x.org/) *(the same DEX aggregation tool powering Matcha.xyz). Learn more about Railway DEX* [*here*](https://docs.railgun.org/wiki/learn/railway-dex-swaps)*.*

### Swaps 

1. From your Public Wallet, **click "dApps" and then "Railway DEX"**.
2. **Select the tokens you want to swap**. *You can import any token if it's not in the current list by pasting its contract address into the token selector.* **Click "Approve"** if this is the first time you're swapping the token.
