Exchange
This is a smart contract to expand Jetton that is created with every liquidity pair. The Router deploys this as new pool creation is requested. Although the Router actually stores the two tokens of a pair and swapping takes place through it, the Exchange Contract must be called for liquidity to be provided or taken.
