Qu'est-ce que « Atomic arbitrage » ?

Definition 25.1 Market Making and High-Frequency Trading · Chapitre 25 — On-Chain Trading

Atomic arbitrage is an arbitrage whose legs all execute in one on-chain transaction, typically across decentralised exchanges and often with a flash loan, so that either every leg succeeds or the whole transaction reverts and only the fee for the failed attempt is lost.

The path of an on-chain arbitrage: searchers see a user’s swap or a centralised price move, build a bundle, and bid for its inclusion in a first-price auction run by a builder, which assembles a block and pays the proposer for including it. Source: One Quant Book 3, chapter 22; this chapter.
