5️⃣ Web 3.0: Test Rigorously

🔹 Testnets for Safe Deployment

• Ethereum: Goerli, Sepolia.

• Solana: Devnet.

• Polygon: Mumbai.

• BSC: Testnet.

🔹 What is this step about?

Before launching on the mainnet, thorough testing ensures your Web3 project is secure, bug-free, and optimized.

🔹 Why does this matter?

Web3 applications deal with real money, meaning any bug can cause massive financial loss.

🔹 Testing Tools

• Hardhat & Truffle – Smart contract testing.

• Foundry – Fast, efficient Ethereum testing framework.

• Testnets (Goerli, Mumbai, etc.) – Deploy test contracts before launching.

Testing reduces risk, increases reliability, and builds trust before deployment.

✅ Final Thought: Never deploy to mainnet without thorough testing—use audits, simulations, and testnets.
