A smart contract is an automatically executed program that specifies the issuance, trading, and management methods of the token. Contract-based tokens are transmitted and traded through blockchain networks, and their value and functions are determined by the corresponding smart contracts. These tokens usually have characteristics such as decentralization, security, reliability, and transparency, and can be used to incentivize user participation in the ecosystem, achieving asset issuance, circulation, and value transfer.
