Blocknative Launches Web3-Onboard to Support Web3 Developers with Improved Data and UI for a Multi-Chain World

Blocknative Ethereum Web3

Blocknative's upgraded Web3 real-time transaction monitoring toolkit enables developers to consistently access pre-chain data across multiple blockchains, providing developers with the missing link for a seamless user experience


San Francisco, March 10, 2022

Blocknative, the Web3 Transaction Orchestration company, releases Web3-Onboard, a major enhancement to the open-sourced enhanced toolkit that enables developers to easily integrate the top hardware and software crypto wallets with their decentralized applications (Dapp). Web3-Onboard with Notify enables dynamic crypto experiences by monitoring pre-chain events across multiple blockchains so crypto wallet users can be notified of transaction status in real-time. 

Over 50 million crypto users engage with Blocknative mempool intelligence through their wallets, while DeFi protocols, totaling over $30B in total value locked, rely on Blocknative infrastructure to enable safe and accurate transactions. Notable wallets relying on Blocknative to offer an improved user experience include Metamask, Ledger, Coinbase Wallet, Tally, Gnosis, and Trezor among others. 

Blocknative CEO Matt Cutler shared, "Web3 is already a multi-chain world, given the advantages of leveraging different protocols based on their strengths; however, chain layering introduces complexity, making it more difficult for developers to present a clean UI to their users, including providing transparency into transaction finalization and fees. The next generation of Onboard provides developers with this missing link to enable a seamless user experience in an increasingly multichain Web3."

Blocknative's Web-Onboard enhances what developers are able to provide to end-users through the incorporation of data to help users transact with confidence across multiple protocols and wallets. By integrating Web3-Onboard, developers can allow users to easily switch between protocols and significantly simplifies on-ramping to Layer-2 protocols, which are increasingly leveraged for their speed and scalability.

Web-Onboard with Notify also offers real-time transaction alerts, improving transaction completion rates and reducing support requests. 

With built-in modules for more than 35 unique hardware and software wallets and leading blockchain networks like Ethereum, Polygon, and Gnosis Chain, Blocknative's Onboard is the easiest, most effective way for developers to add multi-chain web3 wallet support to their projects.
