Request for Quote (RFQ)

The RFQ process begins when a trader, or their application, broadcasts a quote request to a network of market makers. This request is a structured message containing the precise details of the desired trade, including:

• Asset Pair: The tokens to be swapped (e.g., USDC for ETH).
• Size: The exact amount of the input token.
• Settlement Preferences: The target blockchain and preferred settlement method (e.g., on-chain swap, cross-chain via a bridge).
• Deadline: The time window for which the quote is valid. This structured intent allows market makers to price the trade with high accuracy, as all risk parameters are known upfront.

Unlike public order books, RFQ systems facilitate private streaming of quotes. When a request is issued, it is sent directly to a pre-approved list of professional liquidity providers (LPs) or market makers via secure, off-chain channels (like WebSocket or private mempools). Key aspects include:

• Selective Disclosure: Only invited counterparties see the request, preventing front-running and information leakage.
• Parallel Pricing: Multiple market makers can compute and return their best price simultaneously.
• Firm Quotes: Returned quotes are typically firm, meaning the LP commits to filling the trade at the stated price if the trader accepts within the deadline, barring extreme market volatility.

RFQ creates a targeted, auction-like environment for price discovery. Market makers compete privately to offer the best execution for the specific trade size. This process:

• Incentivizes Tight Spreads: LPs compete on price to win the trade, often resulting in better execution than public pools for large sizes.
• Considers Complex Risks: Quotes incorporate costs beyond spot price, such as cross-chain bridge fees, gas costs, inventory risk, and counterparty risk.
• Enables Price Improvement: Traders can often negotiate or receive improved quotes by allowing a brief negotiation round, a process sometimes called Request for Stream (RFS).

Once a trader selects the best quote, the system moves to settlement. This involves submitting a transaction to the blockchain to execute the swap at the agreed-upon terms. Critical components are:

• Atomic Settlement: The swap of assets occurs in a single, atomic transaction, eliminating counterparty settlement risk. Either the entire trade succeeds, or it fails and assets are returned.
• Quote Attestation: The selected quote is often signed by the market maker (signed quote), providing cryptographic proof of their commitment, which is verified on-chain.
• Integration with DEX Protocols: Settlement typically interacts with underlying Automated Market Maker (AMM) pools or other liquidity sources as directed by the market maker's quote.

RFQ systems rely on a permissioned or whitelisted network of counterparties. This is a fundamental distinction from permissionless AMMs.

• KYC/AML & Credentialing: Market makers are often vetted entities subject to Know Your Customer (KYC) and Anti-Money Laundering (AML) checks.
• Credit & Risk Assessment: The system operator assesses the creditworthiness and operational reliability of LPs before granting access.
• Reputation Systems: Performance metrics like fill rate, quote competitiveness, and settlement success contribute to a market maker's reputation within the network, influencing future quote allocations.

RFQ is optimized for specific trading scenarios where its features provide distinct advantages:

• Institutional & Large Trades: The primary use case is for block trades or over-the-counter (OTC)-sized transactions (e.g., $100k+), where slippage in public pools would be prohibitive.
• Cross-Chain Swaps: Ideal for large, cross-chain asset transfers, as market makers can source liquidity across chains and quote an all-in price including bridge costs.
• Complex Derivatives Settlements: Used to source liquidity for settling or rebalancing positions in structured products or derivatives.
• DAO Treasuries & Protocols: Used by decentralized autonomous organizations (DAOs) and other protocols to execute large treasury management transactions with minimal market impact.
