sol-flattener

Mimimal solidity flattener script. No dependencies.

Most analysis tools require the file to be self-contained and compilable directly with solc. This helps flatten solidity file from project folder structure to a single file to be used for tools or to be uploaded to etherscan.

Requirements:

• Python 3

Usage:

Normal project:

• python flatten.py --path yourfile.sol
• python flatten.py --path yourfile.sol --output /temp/

Hardhat + truffle projects:

• Install npm dependencies
  • cd project_folder
  • npm install or yarn install
• python flatten.py --path project_folder/contracts/Contract.sol --include project_folder/node_modules

Test the flattened sol file with the correct solc version : solc Contract_flattened.sol --binary
