Truffle Flattener concats solidity files developed under Truffle with all of their dependencies
npm install truffle-flattener
Truffle Flattener concats solidity files from Truffle and Buidler projects
with all of their dependencies.
This tool helps you to verify contracts developed with Truffle and Buidler
on Etherscan, or debugging them on
Remix, by merging your files and their
dependencies in the right order.
If you are still using Truffle, we recommend you try Buidler,
our Ethereum development environment, which is much faster and flexible.
If you are using Hardhat, you don't need this project. Use npx hardhat flatten instead.
npm install truffle-flattener -g
Just install it with npm in your truffle project and runtruffle-flattener .
Aliased imports (eg: import {symbol1 as alias, symbol2} from "filename";) are
not supported by truffle-flattener.
