After building games and integrations, I wanted something harder: Read someone's wallet. Analyze their on-chain activity. Score them. Reward them with a soulbound NFT based on their history. RetroBase was born. Not random questions. A quiz personalized to YOUR wallet. "How many contracts did you deploy?" "What was your first transaction on Base?" The blockchain remembers everything. I just had to learn how to READ it. That's when I realized: Every transaction is public data. Every contract interaction is readable. The chain is an open book. You just need to learn the language. Built something that reads the chain yet? That's your next level.
