What tanX.fi does

tanX.fi is an institutional-grade decentralized exchange (DEX) operating as a cross-chain orderbook platform built natively on Starkware's StarkEx layer-2, using zero-knowledge (ZKP) and STARK proofs to deliver scalability, self-custody, and trade-intent privacy. The platform supports spot trading across Ethereum, Polygon, Starknet, and Arbitrum and exposes both a self-serve web trading application (trade.tanx.fi) and a full REST/WebSocket API with NodeJS and Python SDKs for institutional automation. Customers include professional traders, OTC desks and exchanges, and regulated banks and brokers, with a direct Fireblocks custody integration enabling trades from institutional wallets.

The company monetizes through a 0.1% (or lower, by tier) transaction fee on trades — with no gas fees and no deposit fees — supplemented by an enterprise tier offering custom maker, taker, and stablecoin fee schedules under multi-year contracts with KYB onboarding, dedicated account management, and SLAs. Core technology differentiators include the cross-chain orderbook architecture, gasless execution via L2 batching, optional KYC-compliant trading with pre-approved counterparties, and advanced order types (Limit, Stop-Limit, Trailing-Stop-Limit, OCO). The legal entity, BRS Tech Services Ltd, is incorporated in the British Virgin Islands; the platform excludes users from the United States, Canada, and various sanctioned jurisdictions.

Strategically, tanX is pursuing expansion beyond spot trading into adjacent product lines — tanX Pay (instant gasless crypto payments), Pro Mode (real-time DeFi dashboard), and Cross-chain APIs (multi-chain fund transfers). The company raised $16.5M in September 2023 led by Pantera Capital with StarkWare Industries, Elevation Capital, Goodwater Capital, The Spartan Group, Protofund, and Upsparks participating. Smart contracts are audited by PeckShield, and the platform claims 4 million orders processed with a 100% success rate across 30+ global partners.

Direct peers

• dYdX: dYdX is a decentralized orderbook perpetuals exchange that migrated to its own app-chain. It is directly comparable to tanX as a non-custodial orderbook DEX targeting professional traders, with similar advanced order types and self-custody model.
• Hyperliquid: Hyperliquid is a high-performance on-chain orderbook DEX for perpetuals built on its own L1. It competes head-to-head with tanX for professional and institutional on-chain orderbook flow, emphasizing CEX-matching-engine-grade latency.
• Aevo: Aevo is an orderbook DEX for derivatives (options and perps) built on an L2. It targets similar institutional and professional trader segments as tanX with an off-chain matching, on-chain settlement architecture and a focus on advanced order types.
• Vertex Protocol: Vertex is a cross-margin orderbook DEX with spot and perpetuals built on Arbitrum. It is highly comparable to tanX as a hybrid orderbook DEX targeting institutional-grade execution, with similar cross-chain ambitions.
• Drift Protocol: Drift is an orderbook DEX on Solana offering spot and perpetuals. It competes with tanX for professional on-chain orderbook flow, though on a different L1 stack; relevant as a comparable hybrid liquidity model.
• CowSwap (CoW Protocol): CoW Protocol is a DEX aggregator that uses batch auctions and intents to deliver MEV-protected execution. It is comparable to tanX as a non-custodial trading venue focused on institutional-grade execution quality and slippage minimization.

Broad incumbents

• Uniswap: Uniswap is the largest AMM-based DEX. While AMM-based rather than orderbook, it represents the dominant decentralized spot venue and the most likely competitive substitute for many of tanX's institutional clients evaluating execution venue.
• 1inch: 1inch is a leading DEX aggregator routing orders across many venues. It is comparable to tanX as on-chain execution infrastructure for institutional traders seeking best execution, though it routes rather than matches orders itself.

Emerging players

• Orderly Network: Orderly is an omnichain orderbook infrastructure protocol that powers white-label DEXs. It overlaps with tanX as a cross-chain orderbook layer targeting institutional and builder audiences, and could be a partner or competitor depending on go-to-market.

Others

• 0x Protocol: 0x is a DEX aggregation and on-chain liquidity protocol providing APIs for wallet and institutional integrators. It is thematically related as enabling infrastructure for non-custodial execution, comparable to tanX's API/SDK-first institutional distribution model.
