On an AMM, the price you see is not the price you get, slippage and MEV eat the difference. Hashflow fixes that with RFQ: professional market makers give a firm, signed quote for your exact trade, so you execute at the quoted price with zero slippage and MEV protection, across chains. When a guaranteed fill matters, on size or volatile assets, that certainty is the point. Here is how it works and the risks.

What is Hashflow?

Hashflow is a decentralized exchange built on RFQ (request-for-quote) liquidity. Professional market makers provide firm, signed quotes for your specific trade, so it executes at the quoted price with zero slippage and MEV protection, across many chains and cross-chain routes. There is no AMM curve to slip along, and because the price is fixed at quote time, sandwich MEV is not a factor.

That price certainty is the differentiator. Where an AMM exposes your trade to slippage and front-running, Hashflow gives you a guaranteed fill from a market maker, enforced by the signed quote.

How Hashflow works

  1. Set your swap, same-chain or cross-chain, and request a quote.
  2. Market makers respond with firm, signed prices for your exact trade.
  3. You accept the best quote, and it executes at that price, no slippage, MEV protected.
  4. Receive your output in your wallet on the destination chain.

Why users choose Hashflow

  • Zero slippage. The quoted price is the executed price, valuable on size.
  • MEV protection. Firm up-front pricing removes sandwich exposure.
  • Cross-chain support. RFQ swaps across chains, not just same-chain.
  • Professional liquidity. Market-maker quotes rather than passive pools.

When to reach for something else: for the absolute best routed price across all sources, compare an aggregator like Odos or 1inch; Hashflow is the pick when a guaranteed, MEV-protected fill matters most.

Risks

Hashflow is non-custodial, and firm signed quotes remove slippage and reduce MEV. Standard risks remain: token approvals (review and revoke unused ones), smart-contract risk, and reliance on market makers honoring quotes (enforced by signatures). RFQ quote availability and quality vary by pair and chain, so compare an aggregator on size. Verify the official URL and start with a small swap on a new route.

How to get started

  1. Open the app and connect a self-custody wallet.
  2. Set your swap (same-chain or cross-chain) and request a quote.
  3. Accept the firm quote and execute at the guaranteed price.
  4. Start small on a new route and manage approvals afterward.

Final verdict

Hashflow sells certainty. Firm, signed RFQ quotes mean zero slippage and MEV protection, same-chain or cross-chain, all non-custodial. For size and volatile assets, knowing your exact fill is a genuine edge over AMMs. Availability varies by pair, so compare an aggregator on the biggest trades, and mind approvals as always. When a guaranteed, MEV-protected price is what you need, Hashflow delivers it. Verify the URL and start small.
