Mini DeFi Bank Update
Today I reviewed and upgraded my contract found flaws, patched ‘em, learned a lot.

🧠 Lessons + Fixes:

✅ Tracked direct ETH in receive() with an event log (didn’t even know I could tbh)

✅ Removed redundant require() in withdraw() (gas savings > over-checking)

✅ Added 24hr cooldown per withdrawal

✅ Built 10% annual interest logic primary school math finally paid off 😅


Next:

🎯 .reset() function for test mode

🎯 Testnet deploy this weekend 🧪


How would you test a Defi Bank contract?
