XC-20s Overview Learn about the types of cross-chain assets on Moonbeam, in particular, local and external XC-20s, and view a list of the external XC-20s on Moonbeam. Interact with XC-20s Check out the XC-20 Solidity interfaces, including the ERC-20 and ERC-20 Permit interfaces, and how to interact with external XC-20s using these interfaces. Send XC-20s Learn how to send XC-20s to other chains using the X-Tokens Pallet. The X-Tokens Precompile allows you to access core functions via the Ethereum API.
