The Top Blockchain Developer Frameworks for 2021
The best smart contract and blockchain developer frameworks, focusing on Ethereum smart contracts across all languages
Smart contract development frameworks make engineers’ lives easier by allowing them to deploy and test their smart contracts. I took hours and days to go through every recommended framework from ConsenSys and the Ethereum website to see which ones are the best for 2021. You can see my experimentation with the platforms on GitHub.
Not only that, but I’ve conducted hundreds of interviews with blockchain hackathon participants and gone through hundreds of hackathon submissions, looking for which tools perform the best and have the best developer experience. I also do a lot of work using each framework myself, and I want to set myself up for 2021 right. I’ve done the hard work for 2021 so you don’t have to.
The criteria used was simple. The framework needs to:
- Deploy to a local blockchain
- Have quick and effective testing
- Deploy a smart contract, using Chainlink, to the Kovan Testnet.
The third criterion is important because it allowed me to test how the framework interacts with other packages and integration testing. Working with oracles and third-party tools like OpenZeppelin is basically a must for 2021, which is why this last piece is so important.
We are going to briefly mention some other important tools that you need to know about for 2021, but this article will not go over beginner tools, like an ETH wallet, an Ethereum client, or a text editor.
Top 3 Smart Contract Development Frameworks
When it came down to it, there are three smart contract development frameworks that I would recommend to anyone. Each has a slightly different flavor and reason why you’d choose it. They are:
- Hardhat (JavaScript)
