Solidity : Smart Contract rule 본문
728x90
1. SPDX - License - Identifier
ex . //SPDX-License-Identifier: MIT
: In each file of the project, add a line at the top that matches the license.
- Determine the License applied to the file
- License standardization of source code and documents
- Eliminate error-prone license header parsing
2. Pragma solidity
ex. pragma solidity >= 0.7.0 < 0.9.0;
: Indicates the solidity compiled version of the currently written smart contract. An error occurs if you use a compiler other than the predefined compiler version.
3. contract
ex. contract EX1 {}
: This is a keyword that announces the start of smart contract creation, and the name can be specified right next to it.
