About Project

The extensible Solidity developer tool.

Buidler is an extensible developer tool that helps smart contract developers increase productivity by reliably bringing together the tools they want.


Use from the command line. Use as a library. Override default behaviour. Customize your workflow by creating your own tasks and installing your favorite plugins.


Buidler's core is small, fast and maintained with very high standards of quality. Buidler will never stop working out of the blue.


Web3.js, ethers.js, Truffle4 or Truffle5? Anything goes. Your tools, your libraries, your choices.
