#套利交易策略 Hashflow's RFQ (Request for Quote) engine is based on a quote competition mechanism that directly connects traders with market makers. The specific workflow is as follows:

1. User submits a trade request: The user specifies the desired trade on the Hashflow interface, such as the type of asset being traded, quantity, and other information.

2. Request broadcast to market makers: The request is privately broadcast to a network of professional market makers. These market makers manage pools of assets, possess strong pricing capabilities, and have ample liquidity.

3. Market makers calculate and submit quotes: Market makers run advanced pricing models off-chain, integrating data from centralized exchanges, their own inventory levels, and real-time volatility, to calculate competitive quotes, which they submit to the Hashflow system in the form of a cryptographic signature.

4. User receives and selects a quote: After collecting all market makers' quotes, the Hashflow system presents the best quote to the user. This quote is a cryptographically signed message, ensuring the validity of the price and amount. The user can choose to accept or reject the quote.

5. Trade execution: If the user accepts the quote, the signed quote is submitted to the on-chain Hashflow smart contract. The smart contract verifies the validity of the signature, and upon confirmation, executes the trade, transferring funds from the user's account to the liquidity pool and completing the corresponding asset exchange.
