Ethers.js was developed by Ethers originally for ethers.io, but has since become a powerful lightweight library for connecting DApps with blockchain data. Users can use Ethers.js functionality as a full Ethereum wallet. Additionally, developers building with Ethers.js get full access to the Ethereum blockchain with block and wallet queries, ENS address resolution, direct connection to nodes, and more. Ethers.js currently powers over 18,000 Web3 projects on GitHub.
