### Contract Description

Contract	Description
ERC-20 Contract	The main contract that mints and redeems the fungible tokens. It cooperates with the messaging contract to send tokens and mint budgets across different chains. It’s an upgradable contract. Its privileged operations are carried out in a time-locked way.
ERC-721 Contract	The main contract that mints and redeems the non-fungible tokens. During the minting and redeeming process, it cooperates with the ERC-20 contract to lock and unlock corresponding fungible tokens. It does not support cross-chain transfers. It’s an upgradable contract. Its privileged operations are carried out in a time-locked way.
Messaging Contract	The adaptor contract that connects XAUm to cross-chain protocols. Users call this contract when sending tokens and mint budgets to remote chains. Currently, this contract uses Chainlink's CCIP and LayerZero.
