RFQ Engine

Not an AMM.
Never Was.

Hashflow DEX replaces the AMM with a Request-for-Quote engine. Instead of computing price from a pool formula, it sources signed quotes from professional market makers who compete to give you the best price.

01
Request
You connect your wallet and enter a trade. Hashflow DEX broadcasts an RFQ — a request for quote — to its network of professional market makers simultaneously. No slippage parameter needed.
WALLET CONNECTED · BROADCAST TO MMS
02
Signed Quote
Market makers respond with cryptographically signed firm quotes — exact prices they will honor. The signature locks the price. This is why Hashflow DEX can guarantee zero slippage: the price is fixed before you submit.
CRYPTOGRAPHIC SIGNATURE · FIXED PRICE
03
Best Quote Selected
Hashflow DEX selects the best signed quote from the competing market makers and presents it to you. The price is guaranteed — not an estimate, not subject to AMM math, not vulnerable to MEV bots.
BEST QUOTE · COMPETITIVE MMS · GUARANTEED
04
Atomic Execution
You sign and submit. The smart contract verifies the market maker's signature on-chain and executes atomically at the quoted price. MEV bots see a signed transaction — they cannot change the price or insert their transaction to benefit.
ATOMIC · ON-CHAIN VERIFIED · ZERO MEV
Why RFQ beats AMM
Firm price before you trade
AMM price is computed from a pool formula at execution time — it changes with every block. RFQ price is cryptographically signed before execution. Result: Hashflow DEX users always receive exactly what was quoted, regardless of trade size or market volatility during confirmation.
Market maker network
50+ professional quoting firms
Hashflow DEX's market maker network includes Wintermute, GSR, Amber Group, Cumberland, and 45+ institutional firms who compete to offer the tightest spreads. Competition between MMs drives better prices for traders — not AMM pool depth.
Cross-chain RFQ
Same guarantees across all chains
Hashflow DEX extends the RFQ model to cross-chain swaps — ETH to BNB, Polygon to Avalanche, and all supported pairs. Market makers provide signed quotes covering both chains, so you get zero-slippage execution even on multi-chain trades. No bridging complexity exposed to users.

RFQ vs AMM

Why RFQ Wins.

AMMs like Uniswap, Curve, and SushiSwap are vulnerable to slippage, MEV, and price impact. Hashflow DEX eliminates all three through the RFQ model.

FAQ

RFQ & Hashflow DEX Questions Answered

Everything about RFQ trading, zero slippage, MEV protection, market makers, supported chains, HFT token, and how Hashflow DEX compares to AMM DEXes.

  • Hashflow DEX is a multi-chain decentralized exchange (DEX) built on a Request-for-Quote (RFQ) engine, not an Automated Market Maker (AMM). Instead of computing prices from pool formulas, Hashflow DEX sources cryptographically signed quotes from professional market makers — giving traders zero slippage, zero MEV, and zero protocol fee on every swap. It operates across Ethereum, Arbitrum, BNB Chain, Polygon, Avalanche, Base, and more. Access it at hashflow-dex.pro.
  • An RFQ DEX works differently from AMM DEXes like Uniswap. Instead of computing a price from a pool formula at execution time, an RFQ DEX broadcasts a trade request to professional market makers, who respond with cryptographically signed firm price quotes. The DEX selects the best quote. Because the price is signed before execution, it cannot change — this delivers zero slippage, zero MEV risk, and zero price impact regardless of trade size.
  • Slippage on AMM DEXes occurs because the execution price is computed from a formula at the moment the transaction is confirmed — not when you click swap. Between click and confirmation, prices move. Hashflow DEX eliminates this by having market makers cryptographically sign a fixed price before you submit. The on-chain smart contract verifies this signature and executes at exactly the signed price — not subject to price movement or formula recalculation.
  • MEV (Maximal Extractable Value) bots monitor the public mempool for pending swap transactions and front-run them — inserting their own transaction just before yours to profit from the price movement your trade causes. Hashflow DEX is structurally immune to MEV because the RFQ quote is cryptographically signed by the market maker at a specific price. Even if a bot sees your pending transaction, it cannot change the execution price — the signature locks it. No slippage tolerance = no sandwich attack surface.
  • Hashflow DEX charges 0% protocol fee. This is one of the most significant advantages over AMM DEXes, which typically charge 0.01%–1% on every trade. Market makers on Hashflow DEX earn revenue from the bid-ask spread on their signed quotes — not from a protocol-imposed fee on top of the trade. You pay only the blockchain gas fee for the transaction.
  • Hashflow DEX's market maker network includes Wintermute, GSR, Amber Group, Cumberland DRW, and 45+ other institutional trading firms. These are the same firms that price institutional OTC desks and traditional HFT infrastructure. By competing on Hashflow DEX, they bring institutional-grade pricing to retail DeFi traders — tighter spreads and better execution than any AMM pool can achieve on similarly sized trades.
  • Hashflow DEX supports Ethereum, Arbitrum, BNB Chain, Polygon, Avalanche, and Base, with Optimism, zkSync, and additional chains in expansion. Cross-chain swaps between all supported chains are also available through the native Hashflow cross-chain RFQ, which applies zero-slippage guarantees on the source chain and routes to the destination chain atomically.
  • The key differences: Uniswap uses an AMM (x*y=k formula) that charges 0.01%–1% fees, is vulnerable to MEV/sandwich attacks, and causes price impact proportional to trade size. Hashflow DEX uses RFQ with signed quotes — zero slippage, zero MEV risk, zero protocol fee, and no price impact regardless of trade size. For smaller retail swaps in highly liquid pairs, Uniswap may occasionally match Hashflow pricing. For larger trades, Hashflow DEX consistently outperforms.
  • Hashflow DEX supports MetaMask (all supported EVM chains), WalletConnect (200+ mobile wallets), Coinbase Wallet, Rabby Wallet, and Phantom. Any EVM-compatible wallet that connects via WalletConnect will work. Because Hashflow DEX is non-custodial, your private keys remain on your device and are never required by the protocol. Connect at hashflow-dex.pro by clicking "Connect Wallet."
  • HFT is the Hashflow governance and utility token. HFT holders can participate in governance votes over protocol parameters, fee distributions, and chain expansion decisions. HFT can also be staked on Hashflow DEX to earn a share of protocol revenue. The token is an ERC-20 on Ethereum and available on all supported Hashflow DEX chains. Staking rewards come from protocol fee revenue collected across all chains.
  • Hashflow DEX's cross-chain RFQ extends the signed quote model across chains. A market maker signs a quote that covers both the source chain execution and the destination chain delivery. The source chain contract verifies the signature and locks your tokens; the destination contract releases the quoted tokens to your wallet. Zero slippage is guaranteed on the source chain. Supported cross-chain pairs include ETH→BNB, Polygon→Avalanche, Ethereum→Base, and all supported network combinations.
  • Yes — and this is one of Hashflow DEX's biggest advantages over AMMs. AMM slippage scales with trade size: a $1M trade moves price significantly more than a $1K trade. In Hashflow DEX's RFQ model, the market maker signs a specific price for the specific trade size you requested. A $1M signed quote executes at the signed price regardless of pool depth. Large trades often see better relative pricing on Hashflow DEX than on AMMs.
  • Price impact is the effect your trade has on the market price — in AMMs, your trade moves the pool price according to the x*y=k formula, so larger trades cause larger price impact. Hashflow DEX has zero price impact because prices are set by market makers, not by pool formulas. The market maker quotes you a firm price for your exact trade size, independent of any pool state. Your trade does not "move" any price curve.
  • Hashflow DEX has a Pool module where you can deposit token pairs to provide liquidity that professional market makers draw from to fill RFQ quotes. You earn a share of trading fees proportional to your pool share. Navigate to the Pool tab in the swap widget, connect your wallet, select a pair (e.g., ETH/USDT), and deposit. Unlike AMM LP positions, Hashflow pools don't expose you to the same impermanent loss dynamics because market makers actively manage inventory.
  • Yes. Hashflow DEX is fully non-custodial — your tokens remain in your wallet until the trade executes atomically. No private keys are ever shared with the protocol. The Hashflow smart contracts only take custody of your tokens at the moment of trade execution, and only transfer them after verifying the market maker's signature on-chain. If the transaction fails for any reason, your tokens stay in your wallet.
  • No. Hashflow DEX is permissionless — no account, no email, no KYC required. Connect your wallet at hashflow-dex.pro and you can trade immediately. Your wallet address is the only identity the protocol knows. Note: certain regions may be geo-restricted from using the frontend based on regulatory requirements, but the underlying smart contracts are permissionless and accessible directly on-chain.
  • An AMM is a smart contract that holds two or more tokens in a pool and uses a mathematical formula (typically x*y=k, or variants like Curve's stable formula) to compute trade prices based on the pool's token balances. AMMs enable permissionless token trading without order books or counterparties. The tradeoff: price depends on pool depth, large trades cause price impact, AMMs are vulnerable to MEV, and they charge LP fees. Hashflow DEX uses RFQ instead of AMM to eliminate these limitations.
  • On AMM DEXes, slippage tolerance is how much worse than the quoted price you'll accept. If set too low, your transaction reverts. If set too high, MEV bots exploit the gap. Hashflow DEX has no slippage tolerance setting because no slippage is possible — the market maker's signed quote is the execution price. You never need to configure slippage tolerance or worry about failed transactions due to price movement.
  • Hashflow DEX supports all major tokens on each supported chain where market makers provide RFQ quotes. This includes ETH, WBTC, USDT, USDC, DAI, BNB, MATIC, AVAX, ARB, OP, LINK, UNI, AAVE, CRV, MKR, and hundreds of other ERC-20, BEP-20, and compatible tokens. The token list is determined by active market maker coverage — MMs only quote pairs they have inventory for. Token availability varies by chain.
  • Impermanent loss (IL) is a risk specific to AMM liquidity providers — when the price ratio between pooled tokens changes, LPs end up holding more of the losing token and less of the winner compared to simply holding both tokens. Hashflow DEX's pool structure has reduced impermanent loss exposure because professional market makers actively manage the inventory — they hedge and rebalance, reducing the systematic IL that passive AMM LPs experience. Liquidity providers on Hashflow pools benefit from active MM inventory management.
  • When you enter a trade on Hashflow DEX, the frontend sends an RFQ (request for quote) to Hashflow's off-chain quoting infrastructure, which broadcasts it to all active market makers. MMs respond within milliseconds with signed quotes. The Hashflow system selects the best quote (highest output for the trader) and displays it. You then approve — the signed quote is submitted to the on-chain contract which verifies the signature and executes at the stated price. The entire process takes under 2 seconds.
  • Key risks to be aware of: Smart contract risk — despite audits, all on-chain code carries residual risk. Market maker counterparty risk — MMs must have sufficient inventory to fill quotes; if a MM's systems fail, a quote may expire unfilled (your tokens stay in your wallet). Bridge risk on cross-chain swaps. Regulatory risk in some jurisdictions. Hashflow DEX mitigates these through audited contracts, multi-MM redundancy, and the atomic execution model where failed trades always revert.
  • Hashflow DEX has processed over $11 billion in cumulative trading volume since launch across all supported chains. Volume is verifiable on-chain through the Hashflow smart contract event logs and is tracked on DeFiLlama, Dune Analytics, and DefiPulse. Ethereum and Arbitrum represent the largest volume share, followed by BNB Chain. Daily active volume is visible in real time at hashflow-dex.pro/analytics.
  • Yes — Hashflow DEX is purpose-built for large trades. The RFQ model scales perfectly with trade size: a $10M trade gets the same zero-slippage guarantee as a $1K trade. Market makers quote for the specific size requested, not from a pool formula that degrades with size. Many institutional traders and DeFi protocols use Hashflow DEX as their primary execution venue precisely because AMMs cannot match the execution quality at scale. The protocol has executed individual trades exceeding $100M with zero slippage.
  • A sandwich attack is an MEV attack where a bot detects your pending swap in the mempool and places two transactions: one before yours (buying the token you're buying, driving up the price) and one after yours (selling it to you at a higher price). This steals value from your trade. On Hashflow DEX, sandwich attacks are impossible: the RFQ quote is cryptographically signed at a fixed price. Even if a bot sandwiches your transaction, the on-chain contract rejects execution at any price different from the signed quote.
  • Gas costs on Hashflow DEX vary by chain. On Ethereum mainnet, Hashflow trades use approximately 120,000–180,000 gas — comparable to Uniswap V3 swaps. On L2s like Arbitrum and Base, gas costs are dramatically lower (under $0.10 typical). Hashflow DEX requires slightly more gas than pure AMM swaps due to the signature verification step, but this is offset by the zero protocol fee — on larger trades, the fee saving far exceeds the marginal gas premium. Gas estimate is shown in the quote before you confirm.
  • Hashflow DEX protects traders from bad-faith market makers through several mechanisms: Competition — multiple MMs quote simultaneously and Hashflow always selects the best for the trader; any MM quoting artificially poor prices loses business. On-chain verification — quotes are signed and verified on-chain, so MMs cannot change the price post-quote. Expiry — quotes have short validity windows (typically 30–60 seconds), preventing MMs from holding quotes and only filling favorable ones. Reputation — MMs are known entities with reputational stake in the market.
  • DeFi (Decentralized Finance) is a category of financial applications built on public blockchains that operate without centralized intermediaries. DEXes (decentralized exchanges) are a core DeFi primitive — they allow peer-to-peer token trading governed by smart contracts. Hashflow DEX sits at the frontier of DEX innovation: rather than following the AMM paradigm that dominated DeFi since 2020, it introduces professional market maker infrastructure to on-chain trading, bridging institutional TradFi execution quality with DeFi's non-custodial principles.
  • Yes. Hashflow DEX smart contracts have been audited by leading security firms including Consensys Diligence, Trail of Bits, and other reputable auditors. Audit reports are publicly available. Hashflow also runs a bug bounty program for ongoing white-hat security research. The RFQ model itself reduces smart contract surface area compared to AMMs — signature verification requires less complex on-chain logic than full AMM pool math, reducing the attack surface for exploits.
  • Hashflow DEX, like most DeFi protocols, experienced reduced trading volume during bear market periods. However, the RFQ model proved more resilient than AMMs during volatility: when AMM pools saw significant imbalances and LPs withdrew liquidity, Hashflow's professional market makers continued quoting. The protocol maintained functionality through multiple market cycles. The structural advantages of RFQ — zero slippage, zero MEV — are most valuable during volatile market conditions when AMM slippage and MEV attacks are most severe.
  • Go to hashflow-dex.pro. Click Connect Wallet and connect MetaMask or your preferred wallet. In the swap widget: select Ethereum network, set "You pay" to ETH, set "You receive" to USDT. Enter your ETH amount. Hashflow DEX instantly broadcasts an RFQ to market makers. A signed quote appears within seconds — showing the exact USDT you'll receive (zero slippage). Review the quote, click "Get RFQ Quote" and approve the transaction in your wallet. USDT arrives in your wallet when the block confirms.
  • Hashflow DEX is governed by HFT token holders through on-chain governance. Proposals can cover: chain expansion, protocol parameter changes, market maker onboarding criteria, fee structure adjustments, and treasury allocation. HFT holders vote proportionally to their staked balance. Governance operates through a standard governor contract with proposal, voting, and timelock phases. Staking HFT on hashflow-dex.pro grants both governance rights and a share of protocol revenue.
  • Yes. hashflow-dex.pro is a fully responsive web application. For mobile trading, use the WalletConnect option to connect your mobile wallet (MetaMask Mobile, Coinbase Wallet, Phantom, Trust Wallet, etc.). Alternatively, open hashflow-dex.pro directly in the built-in browser of MetaMask Mobile or Coinbase Wallet app — the DApp browser provides a seamless connection. All RFQ functionality — swap, cross-chain, pool, and staking — is available on mobile.
  • Hashflow DEX's roadmap includes: Chain expansion — Optimism, zkSync Era, Scroll, Linea, and Mantle. RFQ for options and derivatives — extending the signed quote model beyond spot swaps. Institutional API — direct RFQ access for DeFi protocols and aggregators. Enhanced HFT staking — tiered rewards based on lock duration and governance participation. Analytics dashboard — real-time MM competition data and execution quality metrics. Full roadmap at hashflow-dex.pro/roadmap.
