 * 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.
 
 * 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.
-* **non-atomic (cross-chain, CEX/DEX, etc.) arb** are more profitable and less accessible due to capital requirements and risk profile.

+* **statistical arbs** (non-atomic) convey informed strategies that rely on informed information (signal). examples can be arbs that rely on cross-chain or CEX + DEX strategies.
