Hey Product Hunt, I'm Vincent Most crypto data analysts learned blockchain analytics with SQL on two free tools: Flipside and Dune. Flipside shutdown in early 2026. In September, Dune made its free plan view-only, so running a single query now costs $75 a month. The next generation of analysts just lost the place they practiced So I built WizardCamp: a question, a schema, a SQL editor and a grader, on real Ethereum data. It runs in your browser, and Pro is $15 a month (or 12 if you go with the yearly plan) I built the data and BI functions at Binance and Morpho from zero. The skill that mattered most was never SQL syntax. It was knowing what the data means. An internal-call trace carries the full transaction value at its root, so a naive UNION ALL counts the same ETH twice. An inner join to a token metadata table silently drops WBTC. You don't learn that from SQL tutorials on a movie database How it works: - Read the question. The concept, schema and hint are on one screen. - Write the query. Nothing to install, it runs in your browser. - Hit Run. Grading is instant and shows which rows are wrong. What's inside: 80+ exercises across 12 modules (tokens, NFTs, DeFi, traces, MEV, bridges, L2s, RWAs, oracles, stablecoins), plus Uniswap and Aave protocol packs. Five certificates, each with a public link a hiring manager can verify. The first 9 exercises and the SQL Foundations certificate are free. Next up is a Solana track, because learners already asked for it. One ask: try an exercise and tell me where it confused you or where the grader felt unfair. I'm reading every comment today :)
