Recommended tech stack for web3 apps in 2025

ideal tech stack: from editors, tooling for building contracts, frontend libs to seamless UX with gas sponsoring

I’ve been deep in Web3 for a while now, and I’m always checking new tools to see what actually makes building apps easier. As we’re halfway through 2025, I wanted to share the tech stack I’m using and enjoying right now.

This isn’t theory. This is what’s actually working for me day to day. Let’s get into it.

Code Editor

First up: where I write code.

I’ve been using Cursor AI almost every day, and it’s become my go-to.

Why I like it:

• It works super well with Solidity and frontend tools like React and Next.js.

• The AI features are better than Copilot in my experience, especially for accepting changes and using terminal.

• I barely use Google or Stack Overflow anymore—Cursor answers most questions right in the editor (back then it was shitty in Copilot)

Bottom line: it keeps me in flow. That’s all I care about.

Smart Contract Tooling

Used to be a Hardhat guy. Not anymore.

Why I switched to Foundry:

• It’s fast. Like, really fast.

• You write your tests and deploy scripts in a Solidity-style language. Took a second to get used to, but now it feels way more natural.

• Command-line tools are awesome. Clean, powerful, and developer-friendly.

• Bonus: private key management is way more secure than stuffing plaintext keys into an .env file.

Once I switched, I never looked back.

Frontend Integration

When it comes to hooking up your frontend to smart contracts, viem and Wagmi are now my default.

Why I use them:

• Smaller bundle size compared to ethers.js. That means faster apps.

• Most modern Web3 projects are building with these, which makes docs and examples easier to find.

• They work great together, which saves setup time.

Simple, fast, and well-supported. That’s what I want.

Wallet Connection

Every dapp needs wallet connection. This is one part you can’t afford to screw up.

I use Reown.

Why:

• Integrates smoothly with viem and wagmi—no weird workarounds.

• Made by the folks behind WalletConnect. Solid team.

• Advanced features are there if you need them, but the basic setup is super straightforward.

You want this to “just work.” Reown does.

Off-Chain Data Verification

You don’t need this for every project, but if you’re verifying anything off-chain—like exchange balances or social media data—vlayer is my pick.

Why:

• No need to learn Rust or some new language. If you know Solidity and JavaScript, you’re good.

• Works with Foundry out of the box.

• You can prove stuff like “I have 10k Twitter followers” or “I passed KYC” without leaking private data.

(Full transparency: I work at vlayer. But I’d use it even if I didn’t.)

Account Abstraction & Gas Sponsoring

Want to make your app easier for normal people to use? This is where Biconomy comes in.

Why I like it:

• Lets users sign in with email or social logins—no MetaMask setup required.

• You can sponsor gas so users don’t need to worry about ETH for transactions.

• Their dashboard makes it dead simple to set up policies and monitor everything.

Feels like the missing piece if you're building for mainstream adoption.
