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 This section shows you how to send XC-20s cross-chain from Moonbeam to other chains in the ecosystem using the X-Tokens Pallet and X-Tokens Precompile.
