DeepBook V3 exposes a Move API for on-chain composability — protocols can place orders, execute swaps, take flash loans, and manage balances directly from Move smart contracts. This skill covers the Move-level contract interface. Common mistakes include calling swap or order functions with incorrect coin type parameters, forgetting to return flash loan hot potatoes, and misunderstanding the TradeProof authorization model.
