Web3.js is an open source software library that helps integrate with decentralized applications built on Ethereum blockchain technologies. As Ethereum is built on blockchain, Web3.js works as a bridge between the Ethereum blockchain and its users without transcending any rules or data from the blockchain network.

A Web3.Js Developer is an experienced programmer for building decentralized applications using Ethereum development framework and the Javascript library, Web3. When developers use Web3.js, they can craft secure and reliable applications upon a wide-scale peer-to-peer blockchain network with the help of a trustless system of data storage and transfer.

Here are some projects that our expert Web3.Js Developers made real:

  • Creating user authentication features on existing web apps
  • Setting up marketplaces for NFTs
  • Integrating ETH payment systems with React dApps
  • Connecting web sites to TikTok pages
  • Crafting smart contracts on Ethereum technology
  • Writing Typescript & React code
  • Auditing smart contracts prior to deployment

It's projects like these that show the full potential of what a Web3.Js Developer can do for your project. With their knowledge of web development and proprietary scripting language, our experienced developers were able to craft advanced yet secure applications for clients that created real value for all parties involved. With this in mind, we invite you to post your own project and set out to hire a remarkable development team with Freelancer.com today.
