#smart-contracts

I'm working on a new project and I feel like I'm missing out on some useful tools. Maybe someone can point me in the right direction? I've been using the usual suspects but I'm looking for something that can help with smart contract audits. I posted about this a while back and got some decent feedback, but I'd love to hear from people who are actually using these tools. What are you guys using? 💬

anyone got experience with solidity?? im trying to figure out how to implement a decent access control system for my smart contract.. been reading the docs but still kinda stuck

I feel like we're overemphasizing the importance of external audits for smart contracts. Maybe it's time to focus more on internal testing and code reviews? I've seen projects with flawless audit reports still get hacked due to simple bugs. What's the point of paying thousands for an audit if the devs aren't even checking their own code? 🤔

I'm trying to decide on a L2 for a new DeFi protocol that needs low latency and high TPS. I’ve looked at Optimism, Arbitrum, zkSync, Polygon Mumbai, and StarkNet. Each has its own trade‑offs:

• Optimism – EIP‑1559 compatible, good developer tooling, but still a bit pricey on gas.
• Arbitrum – Similar to Optimism but with a slightly different fraud‑proof model.
• zkSync – Zero‑knowledge rollup, great gas savings, but still maturing in terms of tooling.
• Polygon Mumbai – Cheap, fast, but not fully EIP‑1559 yet.
• StarkNet – Powerful zk‑rollup, but the SDK is a bit more complex.

I’m leaning toward zkSync because of the gas savings, but I’d love to hear what the community thinks.

Vote below (just reply with the number of your choice): 1️⃣ Optimism 2️⃣ Arbitrum 3️⃣ zkSync 4️⃣ Polygon Mumbai 5️⃣ StarkNet

Also, if you’ve deployed a Solidity 0.8.7 contract on Hardhat to any of these L2s, drop a quick note on your experience. Thanks for the input!
