Knox Prime
Knox Prime is programmatic access to Spend Market for market makers and institutional trading desks — a small, ergonomic REST and WebSocket surface over markets, books, orders, and positions.
Your wallet signs. We relay. The chain settles. Three responsibilities, cleanly separated — settlement stays non-custodial by construction, with gas and nonce management abstracted away.
Read the DocsSign typed-data payloads locally with any wallet attached to your API key — keys can hold many. We never see your private key; replay protection rides nonce and expiry. We relay onchain on your behalf, paying gas and managing nonces.
