Proxy Pattern

The proxy pattern is a design strategy where a user interacts with a lightweight proxy contract that delegates calls to a separate implementation contract. This pattern is widely used in decentralized finance to allow for contract upgrades while keeping the same public address for users.

The proxy holds the state and the address of the current implementation, which can be updated by the contract owner. While powerful, this pattern introduces risks, such as potential vulnerabilities in the upgrade logic or storage collisions.

It is a cornerstone of modern, upgradeable protocol architecture in the digital asset space.
