Order Flow Auctions Explained

4 min readNov 24, 2023


Centralized exchanges get rekt one after the other, and DeFi is transforming. With the order flow auction model, the limitations of individual DEX platforms are finally coming to an end. This is especially good for traders, as they get better prices and an improved user experience. As a bonus, cross-chain trading is also becoming much easier. This article explores the concept of order flow auctions. You will learn about the main concepts of the order flow auction model, how different actors in DeFi will benefit from it, and how Mangata will act as a liquidity network for cross-chain trading.

Swap Intentions

Users always seek the best trading prices, which an individual decentralized exchange may not always offer. This search for optimal prices led to the creation of DEX aggregators. DEX aggregators compare prices across multiple protocols. However, even aggregators might not capture the best deals available in situations where more sophisticated strategies like flash loans or trading on centralized exchanges are involved. Traditional market makers are increasingly coming back into the picture as they have the option to trade over the counter if they hold the tokens that traders need. So there are a lot of ways to get trades done. But as a trader, you don’t want to spend all your time figuring this out.

Explaining Order Flow Auctions

This is where order flow auctions come into the picture. Basically, order flow auctions allow traders to post their swap intentions. These intentions are then distributed in an off-chain gossip network and different fillers will start to look for a way to fill the swap. They compete over who can make the best offer, which is then selected by the protocol. This system not only simplifies the trading process but also ensures traders access the best available price without the need to manually search through multiple platforms.

Order Flow Auctions are a paradigm shift in DeFi which offers a more efficient way of processing transactions to traders. In order flow auctions, transactions of swappers might be batched together by fillers, who are the third parties responsible for optimizing and executing these transactions. Liquidity sources in this system refer to the pools or venues, such as Automated Market Makers (AMMs) or privately owned liquidity, from where fillers can draw liquidity to execute these batches of transactions. This process ensures better prices for swappers and improves trade efficiency. Current venues that utilize the order flow auction model include UniswapX and CoW Swap.

Mangata’s Role in Order Flow Auctions

Mangata is positioning itself as a liquidity source in the order flow auctions. Fillers will need to find paths to execute swaps, and Mangata offers much-needed cross-chain paths for the fillers. By using multiple ZK-rollups, Mangata ensures a safe cross-chain trading experience. Two initial use cases for Mangata exist in this model:

  1. Direct Execution: Fillers can execute a cross-chain transaction on Mangata. The trade itself is executed directly using the Mangata protocol.
  2. Arbitrage: Fillers can fill the swap with their own liquidity to swappers, then backrun the trade over Mangata for an arbitrage opportunity.

Gas-Free Trading and MEV Minimization

Mangata optimizes for capital efficiency by offering gas-free swaps, making high-frequency trading more accessible to the blockchain economy. Coupled with a working solution that minimizes MEV, Mangata provides a fair and transparent trading environment, safeguarding users from predatory actors that introduce hidden costs for trading.

Future Implications

As Mangata integrates with these advanced models, it is poised to redefine the landscape of DeFi. Its strategic positioning as a liquidity source within order flow auctions, combined with its commitment to efficient and equitable trading, shows Mangata’s commitment to advanced and novel DeFi solutions. Mangata is not just adapting to the DeFi revolution; it is actively shaping its future, leading the charge towards a more inclusive and efficient financial ecosystem.

Mangata’s innovative approach to order flow auctions and liquidity provision marks it as a key player in the evolution of DeFi. By addressing the complexities of decentralized trading with practical solutions, Mangata is pushing the limits in efficiency, fairness, and accessibility in the DeFi space.
