## arbitrage

<br>

### tl;dr

<br>


* since **liquidity on-chain is fragmented** (thousands of pools don't communicate with each other, each providing quotes for swapping assets in real-time), it creates an opportunity to buy low and sell high across different pools. for example, two DEXes offer a token at two different prices so that a token can be bought at the lower-priced DEX and sold on the higher-priced DEX in a single atomic transaction.
* due to the nature of the evm's atomic execution, **atomic arbitrages** are possible (as opposed to tradefi): smart contracts allow the packaging a sequential execution of txs, for a set of conditions. if the conditions are not met, the execution can fail, undoing all the on-chain interactions that just occurred.

* spatial (exchanges are located in different locations)
* triangular (profit from trading loops)
* statistical (rely on mathematical models for high-frequency arbs)
* cross-exchange
* sandwich
