Need guidance

Its great that you already know blockchain basics, Solidity, and Foundry. The next step is simple, start building small, end-to-end.

Pick one clear problem and focus on a use case that truly needs blockchain (e.g., trustless payments, token-gated access, verifiable records). Avoid ideas that could work fine without it.

Go full stack meaning write the contract in Foundry, set up a subgraph (so your frontend loads fast), and build a simple UI with Next.js + Wagmi. Use a local testnet first, then a public testnet before mainnet.

Think security from the start. For it use OpenZeppelin libraries, protect against reentrancy, and run unit + fuzz tests. Never deploy production contracts with your personal wallet; use a multisig if you’re serious.

Design for cost and UX as batch writes to save gas, pick an L2 to keep fees low, and always show users what will happen before a transaction.

Build fast and aim for a working MVP in 3–4 weeks. Release it to friends or community members for early feedback before going public.

Don’t overthink your first project. Small, working dApps teach you more than months of theory. What’s your current idea? We can shape it into a focused first build.

I’ve already built some dApps like a blockchain-based voting system, NFT ticketing (real-world use case), and a decentralized media storage solution where users can store images, videos, or documents and receive an ERC-721 token as proof of ownership. These projects work fine, and I’m exploring more ideas. Could you suggest what should be my next step to go deeper—whether that’s improving scalability, security, exploring L2s, cross-chain dApps, or something else?
