Hyperliquid

Hyperliquid is a perpetual futures DEX running on its own L1 blockchain (HyperBFT consensus). It provides fully on-chain order book matching with sub-second finality, up to 50x leverage on perpetual contracts, and a spot DEX. The API uses EIP-712 wallet signing for authentication — there are no API keys. All trading actions are cryptographically signed by your wallet or an approved agent wallet.
