Beginner Mistakes That Cost Me Redeploys (And How to Avoid Them) (Part 4/4) ERROR 7 - Didn't Flatten Before Verifying: Tried to verify on Basescan, pasted my code, ERROR. My contract imported OpenZeppelin, Basescan needs ALL code in one file. Solution in Remix: right-click your .sol file, "Flatten", copy THAT code for Basescan. It's one click but if you don't know it, you lose 30 minutes. My current checklist: images ready first, wallet modifiable, test on Sepolia, test ALL functions (especially withdraw), save deploy info, verify immediately, flatten before verifying. First deploy: 3 hours, 3 redeploys. Latest deploy: 25 minutes, 0 redeploys. The difference isn't magic experience, it's following order and not skipping steps. @base.base.eth @baseapp @basebuilders

Beginner Mistakes That Cost Me Redeploys (And How to Avoid Them) (Part 3/4) ERROR 4 - Didn't Test Withdraw: Only tested mint. "If it mints well, everything's fine." Two days later withdraw function reverted. Had to redeploy. ERROR 5 - Didn't Save Deploy Info: Deployed, worked, closed Remix. "It's on blockchain, why save anything?" Week later: no idea what compiler version, optimizations, constructor args. Two hours reconstructing everything. ERROR 6 - Didn't Verify Immediately: "I'll verify tomorrow." Three days later didn't remember anything. Deploy and immediately verify on Basescan while everything's fresh. @base.base.eth @baseapp.base.eth @basebuilders

Beginner Mistakes That Cost Me Redeploys (And How to Avoid Them) (Part 2/4) ERROR 1 - No TokenURI Ready: Deployed without knowing where images would be. Result: NFTs looked like gray squares on OpenSea. Had to redeploy. ERROR 2 - Hardcoded Wallet: Put my main wallet directly in code. Two days later wanted to change it (seed phrase in phone, paper, and WhatsApp). Impossible without redeploy. Make payment wallet modifiable from the start. ERROR 3 - No Testnet First: "Base is cheap, just cents." Deploy to mainnet, bug. Redeploy, another bug. Redeploy again. $0.50 in gas + 1 hour lost. Always test on Sepolia first. @base.base.eth @baseapp.base.eth @basebuilders.farcaster.eth
