Overview
The AmmFactory is a relatively simple contract that allows an admin to deploy new MinterAmm contracts. It emits the AmmCreated event upon every successful call to MinterAmm.createAmm, which can be used in the subgraph to query for all existing AMMs.
It is not very interesting for users of the SIREN protocol, because most of its functions contain the onlyOwner modifier and thus can only be called by protocol admins.
