About this API

dYdX is a decentralized exchange founded 2017, the leader in DEX derivatives (perpetuals) since 2021. Like Uniswap (spot DEX), dYdX is a derivatives DEX — non-custodial (your funds stay in your own wallet, not given to a centralized entity) but supports perpetuals. Technically: v3 runs on StarkEx Layer 2 (zk-rollup) for lower gas fees; v4 (2023+) migrated to dYdX's own Cosmos chain. API design borrows CEX experience — uses REST + WebSocket, order placement similar to Binance, but actually generates wallet-signed on-chain orders. Most friendly for traders wanting DEX but CEX-like experience.
