  • MetaMask Integration Tips for React Developers Switching to Blockchain

    What’s the best way to integrate MetaMask into a React dApp when making a switch to blockchain development?

    I’m a React developer with four years of experience, and I’m starting to focus on dApps and smart contracts. I’ve tried out web3.js, ethers.js, and wagmi, but I’m not sure which one is most reliable for handling MetaMask connections and wallet state in production.

    Should I use wagmi or web3-react, or just work directly with the MetaMask API? Are there any security or UX issues I should be aware of when users connect wallets or switch networks?

    If you’ve moved from frontend to blockchain jobs, I’d love to hear what worked for you and what interviewers expect you to know about wallet integration.

    Any advice or examples would be super helpful—thanks!

    When I interview React developers switching to blockchain, I look for a clear understanding of wallet integration best practices. I recommend using libraries like wagmi or web3-react over direct MetaMask API calls.

    These libraries are more robust, future-proof, and help you avoid reinventing the wheel. They also make it much easier to manage wallet state and handle events like account or network changes, which are common pain points for beginners.

    Security is a big deal. I want to see candidates who know not to trust wallet addresses or network info from the frontend alone.

    You should verify everything on the backend and never expose sensitive logic to the client. For UX, I look for developers who think about error handling and user prompts—like what happens if MetaMask isn’t installed, or if the user is on the wrong network.

    If you can talk through these scenarios and maybe show a small demo or code snippet, it really helps. I also appreciate when candidates mention keeping dependencies up to date and following the latest best practices in the ecosystem. That shows you’re serious about building secure, user-friendly dApps.

    From my experience, the key skill to learn for MetaMask integration is understanding how to manage wallet connections smoothly in React. I recommend focusing on libraries like wagmi or web3-react because they simplify handling wallet state, network changes, and account switching. These tools come with hooks that fit naturally into React apps and reduce boilerplate code.

    Also, make sure you know how to handle errors gracefully and provide good user feedback when something goes wrong, like when a user rejects a transaction or is on the wrong network. Security-wise, always verify wallet data on the backend and never trust client-side information alone.

    In interviews, hiring managers often ask about how you handle these edge cases and your approach to UX, so being able to explain your workflow and show practical examples will give you an edge.
