### Contract Description
ContractDescription
ERC-20 ContractThe 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 ContractThe 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.
Messenger ContractThe 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.
--- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://matrixdock.gitbook.io/matrixdock-docs/english/gold-token-xaum/smart-contract/contract-address.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
