On-Chain Arbitrage

Definition ∞ On-chain arbitrage involves profiting from price discrepancies of a digital asset across different decentralized exchanges or protocols operating on the same blockchain. Traders execute a series of transactions within a single block to buy an asset cheaply in one location and sell it for a higher price elsewhere. This strategy relies on speed and precise execution to capitalize on transient market inefficiencies. It contributes to price equalization across decentralized markets.
Context ∞ The discussion surrounding on-chain arbitrage often addresses its role in maintaining market efficiency and the implications of “maximal extractable value” (MEV) strategies. A key debate involves the fairness and transparency of such activities, particularly concerning transaction ordering. Future developments will likely include protocol designs that aim to mitigate front-running and improve the equitable distribution of arbitrage opportunities.
