10 Best On-Chain RFQ Trading Protocols In 2026
1. 0x Protocol
0x is one of the first DeFi liquidity infrastructures and offers its Swap API to many wallets and dApps. Its RFQ system allows professional market makers to submit firm, signed quotes that are settled on-chain.
Blockchains Supported Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, and various newer EVM chains. Pricing & Slippage: API matches RFQ quotes to AMM liquidity and returns the best price.
RFQ fills occur at the quoted price so slippage is effectively zero. Execution Speed Quotes are returned in milliseconds and settlement takes one transaction, confirming at normal block speed.
0x Protocol Feature
| Feature | Explanation |
|---|---|
| RFQ Liquidity | Connects traders with professional market makers for competitive token swap quotes. |
| DEX Aggregation | Sources liquidity across decentralized exchanges to help optimize trade execution. |
| Smart Order Routing | Routes trades across available liquidity sources to seek better execution. |
| Developer APIs | Provides APIs and infrastructure for integrating swaps into decentralized applications. |
2. AirSwap
AirSwap is a decentralized trading network where makers and takers negotiate trades directly, with no central order book or pooled liquidity. Makers run servers which respond to quote requests and settlement is through audited intelligent contracts.
Supported Blockchains Ethereum, Polygon, BNB Chain, Avalanche, Arbitrum and other EVM networks. Pricing & Slippage The maker sets the price, so the taker receives a fixed quote with no slippage. Maker competition drives spreads. Execution Speed Quote exchange is instant, settlement is based on block time. It is suitable for OTC and larger trades.
AirSwap Feature

| Price Negotiation | Enables counterparties to agree on trade prices before blockchain settlement. |
3. Hashflow
Hashflow is an RFQ DEX that is built around professional market makers who quote from their own inventory, not from AMM pools. This avoids impermanent loss and reduces exposure to MEV. Supported Blockchains Ethereum, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Base, Solana. Supports cross-chain swaps.
Pricing & Slippage Zero slippage means traders get a fixed, signed quote and large trades usually get tight spreads. Execution Speed: Quotes are returned in less than 1 second, same-chain trades are settled in one transaction. Bridging is involved in cross-chain trading so it is slower.
Hashflow Feature
| Feature | Explanation |
|---|---|
| Market Maker Quotes | Uses professional market makers to provide executable trading quotes. |
| Cross-Chain Swaps | Supports swapping assets across supported blockchain networks through its cross-chain infrastructure. |
| MEV Protection | Designed to reduce certain front-running and sandwich-attack risks during execution. |

It supports single trades, multi-token swaps and batched orders. Supported blockchains: Ethereum, Arbitrum, Optimism, Base, Polygon, BNB Chain and other EVM chains.
There is also growing support for non-EVM chains. Pricing & Slippage: Since Makers compete in real time this tends to result in tight pricing and quotes are fixed so that slippage is effectively zero. Execution Speed: Quotes are almost instant. Its gasless-style flow is appealing as execution is often handled by makers or solvers, reducing friction for traders.
Bebop Feature

| Trade Optimization | Seeks competitive execution through liquidity sourcing and transaction optimization |
5. 1inch
1inch is a DEX aggregator first and foremost, but it also includes RFQ-style trading via limit orders and Fusion, an intent-based system where resolvers (professional fillers) compete to do swaps. Blockchains supported: Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Avalanche, Base, Gnosis and others.
Pricing & Slippage Fusion uses a Dutch-auction model, which means the price improves to market rate until a resolver fills it. users are protected against front-running and slippage is negligible. Execution Speed: Fills are generally quick, though auction timing could add a few seconds. The user does not need to pay gas for swaps.
1inch Feature
