A smart contract that deploys a unique smart contract for any trading pair.


A smart contract deployed from the Soroswap Factory that enables trading between two tokens.


Liquidity within a pair is pooled across all liquidity providers.

Liquidity provider / LP

A liquidity provider is someone who deposits an equivalent value of two tokens into the liquidity pool within a pair. Liquidity providers take on price risk and are compensated with fees.

Mid price

The price between what users can buy and sell tokens at a given moment. In Soroswap this is the ratio of the two token reserves.

Price impact

The difference between the mid-price and the execution price of a trade.


The amount the price moves in a trading pair between when a transaction is submitted and when it is executed.


Smart contracts that are essential for Soroswap to exist. Upgrading to a new version of core would require a liquidity migration.


External smart contracts that are useful, but not required for Soroswap to exist. New periphery contracts can always be deployed without migrating liquidity.

Flash swap

A trade that uses the tokens being purchased before paying for them. Currently flash swaps are not supported in Soroswap as Soroban does not supports reentrancy.
