Proxy Contract

A contract that forwards (delegates) calls to a separate implementation contract, allowing the underlying logic to be upgraded without changing the address users interact with. Common patterns include OpenZeppelin's Transparent Proxy and UUPS (Universal Upgradeable Proxy Standard). The user-facing address holds the proxy; the actual logic lives at an implementation address that can be replaced by an admin. Etherscan's 'verified contract' label on a proxy means the proxy code is verified — not necessarily the implementation. Always check both the proxy and the current implementation when evaluating any upgradeable contract.
