Proxy Contract

A smart contract pattern that separates the contract's logic from its storage, allowing the logic to be upgraded while keeping the same address and data.

Definition

A smart contract pattern that separates the contract's logic from its storage, allowing the logic to be upgraded while keeping the same address and data. Users interact with the proxy, which delegates calls to an implementation contract. This is how most major DeFi protocols handle upgrades.
