What is TanX.fi?

TanX.fi is a non-custodial order-book exchange that runs on top of StarkWare's StarkEx engine, letting traders, OTC desks, and brokers execute spot trades from MetaMask or Fireblocks across Ethereum, Polygon, Starknet, and Arbitrum without paying gas per fill. The platform uses zero-knowledge proofs for privacy, supports compliant trading with whitelisted counterparties, and exposes the same liquidity through REST APIs and a Node.js SDK.
