Need Guidance on Building a Simple dApp on Polygon PoS

Hello all,

I am a developer with a good bit of experience with JavaScript and backend systems, but pretty new to Web3. I’ve read enough about Polygon, and I love the ability to support scalability with low fees. I’d like to build a basic decentralized app (token transfers or even a simple voting or something) on the Polygon PoS proof of stake side as part of my learning.

Is there anyone here who can point me in the right direction on a collection of good up to date resources or even share any tutorials that go beyond deployments and provide a real step-by-step with connecting the front-end and the polygon server through Metamask (using React)?

I came across this website:https://forum.polygon.cissptraining.technology/t/pre-pip-polygon-pos-bridge-liquidity-program/20284/20 but still need guidance.

I’m also wondering if there are specific tools/libraries optimized for Polygon development (like ethers.js, wagmi or otherwise).

Lastly, what are some potential pitfalls to be aware of when working and testing on Mumbai, prior to going live on mainnet?

I’m super welcome to any thoughts from experienced devs or community leads.

Thank you in advance.
Best,
mathew

Hey Mathew, welcome to Web3! For building on Polygon PoS, you’re on the right track. Use ethers.js or wagmi (great with React) to connect to wallets like MetaMask. For tutorials, check out buildspace.so, Alchemy’s Polygon docs, and thirdweb—they have step-by-step guides. Start on Mumbai testnet, but watch for RPC rate limits and faucet delays. Also, always double-check gas settings and contract addresses before mainnet deployment.
