Glossary
User: Individuals or institutions who need assets cross-chain and data transmissions between chains.
Decentralized Market Maker (DMM): Individuals or institutions who provide liquidity to the protocol.
Platform: The decentralized network built by X Protocol.
Address: Blockchain wallet address.
Contract: Blockchain smart contract.
Tokens: On-chain assets, eg: ETH, ERC20, ERC1155, ERC721.
