Solv Yield - Bearing Tokens

The `SftWrapRouter` contract inherits upgradeable contracts, indicating that it is part of an upgradeable system. Upgradeable contracts often pair with a proxy contract that is responsible for managing contract upgrades. The privileged roles of the proxy often have the authority to update the implementation contract. Any compromise to the privileged account may allow a hacker to take advantage of this authority and change the implementation contract which is pointed by proxy and therefore execute potential malicious functionality in the implementation contract.
