A Python package to unfold soldity code with imports into a single file.

Project description

Solidity Unfolder

Unfolds all local imports in a solidity file to generate a flat solidity file.


Manually combining all imports in a solidity file when verifying your contract source on Etherscan is time-consuming and cumbersome. This tool automatically traverses the dependency graph of imports and combines them in the correct order, which is ready to be pasted into the contract verifier.

NOTE: This tool won't work with imports that are aliased (i.e. import "./foo.sol" as bar; )


There's no any requirements for this tool.

pip install solidity-unfolder


usage: solu [-h] [-o *.sol] *.sol *.*.*

Unfolds all local imports in a solidity file to generate a flat solidity file.
Put the output file into out/ folders.

positional arguments:
  *.sol                 target filename with imports
  *.*.*                 solidity compiler version e.g. 0.4.24

optional arguments:
  -h, --help            show this help message and exit
  -o *.sol, --output *.sol
                        output filename (default: flat.sol)


Feel free to contact me if there's any problems. And welcome to open issues and send pull requests.
