Briefings
Walraswap is a decentralized exchange protocol developed by Flashbots in 2023 that integrates external AMM liquidity to solve MEV issues via batch trading. It operates on Ethereum by treating trade orders as equilibrium variables, ensuring all orders are executed without token deficits or surpluses. Unlike previous batch systems, Walraswap uses public order flow and external AMMs to prevent censorship by solvers, incentivizing honest behavior through repeated-game theory. The system computes a unique equilibrium price vector for aggregate token supply, allowing external swaps to execute at their own pricing rules rather than batch clearing prices.
Key points
- Walraswap was developed by Flashbots in 2023 as a solution to MEV in decentralized exchanges on Ethereum.
- The protocol uses public order flow and external AMMs to prevent solvers from censoring trade orders for profit.
Context
Walraswap emerged from research on equilibrium-based batch exchanges, addressing MEV challenges in Ethereum DEXs. It builds on prior work by Ramseyer et al. and integrates external AMM liquidity to create a unique equilibrium solution where all trade orders are executed without token deficits or surpluses.
Limitations
Evidence is limited to the research article and informal intro; no live system data, user metrics, or performance benchmarks are provided. The paper's Section 8 discusses theoretical applicability but does not confirm operational status or real-world deployment metrics.
