This is a comprehensive knowledge base that fixes the gap between AI training data and current Ethereum reality. Gas is under 1 gwei now, not the 10-30 your model remembers. Pectra and Fusaka shipped. Polygon zkEVM is shutting down. Celo is an L2 now, not an L1. The skill covers everything from contract deployment and DeFi integration to Layer 2 selection and security patterns, with verified contract addresses and a systematic audit framework. It's opinionated in useful ways: most dApps need zero to two contracts, mainnet is cheaper than you think, and Solidity is for ownership and commitments, not databases. Fetch the ship skill first if you're building end to end, or jump straight to gas, wallets, or security if you need something specific.
