fbnhnsl/Preprocessed_Solidity_Dataset_V1

This dataset consists of 4,134 unique Solidity files. The files were gathered from three sources: Etherscan, Github and DISL dataset. Six preprocessing steps were applied:

• Step 1 "Cleaning": Unnecessary parts such as comments or blank lines were removed from each file.
• Step 2 "Formatting": Each file was converted with Prettier (and the corresponding Solidity-plugin) so that the final model only generates code in a correct format.
• Step 3 "Slither Analysis": Each file has been checked for security vulnerabilities and gas consumption issues. Annotations are added to the line or construct in which the vulnerability or optimization issue was detected. The entry "secure" is 0 for vulnerable contracts and 1 for secure contracts. The following Solidity code snippet shows an annotation example. The exact position of the vulnerability, the vulnerability and a recommendation how to avoid it are given.

 // WARNING Optimization Issue (immutable-states | ID: 21fb30b): DYORNFA._feeAddrWallet1 should be immutable
 // Recommendation for 21fb30b: Add the ’immutable’ attribute to state variables that never change or are set only in the constructor.
 address payable private _feeAddrWallet1;

 // WARNING Vulnerability (unused-return | severity: Medium | ID: 3032186): AlcoholicApe.createUniswapPair() ignores return value by IERC20(_pair).approve(address(_uniswap),type()(uint256).max)
 // Recommendation for 3032186: Ensure that all the return values of the function calls are used.
 function createUniswapPair() external onlyOwner {
 require(!_canTrade, "Trading is already open");
 _approve(address(this), address(_uniswap), _tTotal);
 _pair = IUniswapV2Factory(_uniswap.factory()).createPair(
   address(this),
   _uniswap.WETH()
 );
 // unused-return | ID: 3032186
 IERC20(_pair).approve(address(_uniswap), type(uint).max);
 }

• Step 4 "Splitting": Each file was splitted according to the definitions (i.e. contract, interface or library) it contains. The required imports were added to the splitted files accordingly.
• Step 5 "Similarity Check": Duplicate and very similar contracts were removed.
• Step 6 "Solhint Fixes": Some of the best practice issues detected by Solhint were fixed in the files.
