tokenProtections
This address has the access to pause and unpause controller contract.
This address has access to configure lossless protocol. Can be changed by recoveryAdmin
.
This is a super admin's address. This wallet is able to change the regular admin and pause admin. This address is the most powerful admin in the whole lossless protocol and we are using a secure and time tested multi-sig (Gnosis Safe) for it. This variable can be changed using transferRecoveryAdminOwnership
function.
The address of the guardian smart contract. Guardian contract has access to control protection strategies on controller contract.
This mapping saves info about every address that is protected. It has a flag that shows if the address is protected or not and also has strategy address so that if the address is protected the controller knows which of the protections strategies should be applied.
