Brine — now rebranded as tanX — is a cross-chain, self-custodial orderbook decentralized exchange (DEX) built on StarkWare's StarkEx Layer-2 scaling engine. It combines the trustless, non-custodial security of a DEX with the speed and low fees of a centralized exchange: gasless trading, rapid off-chain order execution with on-chain settlement, cross-chain deposits and withdrawals, and simple APIs for programmatic trading. The company is backed by Pantera Capital and is repositioning around "a secure and compliant future for crypto." This API Evangelist profile was seeded from Pantera Capital's portfolio and enriched by the pipeline; as of this pass the public REST API host is no longer reachable and the developer surface is limited to the GitBook documentation.
