About Web3 Onboard ​​Blocknative’s Web3 Onboard is an open-source, framework-agnostic JavaScript library to onboard users to web3 apps. Launched in 2019, Web3 Onboard is the quickest and easiest way to add multi-wallet and multi-chain support to a project. With built-in modules for more than 80 unique hardware, software, and browser wallets, Web3 Onboard saves developers time and headaches related to the UI and logic of connecting wallets to dapps throughout the EVM.
