Click on a contract file to edit the code.

## 2. Compile a contract Once your contract code is written, click on the "Compiler" button in the right-side menu to open the compilation module. Choose the compiler version and decide whether to enable optimization, then click "Compile \*\*\*.sol" to initiate the compilation.

After successful compilation, the [ABI](https://docs.soliditylang.org/en/latest/abi-spec.html) and BYTE CODE will be displayed below, and you'll see a message in the console stating "Compile contract success."
