"Builder has become an essential part of our development and Continuous Integration stack. At Connext, we develop and test complicated smart contract systems for our state channel implementations, making proper Solidity tooling a key to our productivity and success. Hardhat's state-of-the-art Solidity stack trace and console.log features saved us considerable development time. As a user, it's clear that Hardhat prioritizes a great developer experience, which aligns fully with Connext's values. We enjoy interacting with the team and we have even made contributions to the project."
