Hashflow

Hashflow is a decentralized exchange (DEX) and the leading request-for-quote (RFQ) trading platform in crypto. Instead of an automated market maker (AMM) pricing curve, Hashflow brokers signed, off-chain-priced quotes from a network of professional market makers, giving traders zero-slippage, MEV-protected swaps across EVM chains and Solana, including cross-chain trades. Market makers publish price levels and respond to RFQs with EIP-712 signed quotes that settle on-chain via the HashflowRouter contract. Developers integrate through the Taker API v3 (market-makers, price-levels, rfq, and restrictions endpoints) and market-maker tooling, with first-party JavaScript and Python SDKs.

Hashflow publishes 2 APIs on the APIs.io network. Tagged areas include Company, Defi, DEX, RFQ, and Trading.

Hashflow’s developer surface includes documentation, API reference, getting-started guide, engineering blog, signup flow, support, pricing, and 17 more developer resources.
