How Is the Upgrade Function Typically Triggered in a UUPS Contract?
In a UUPS contract, the upgrade function (e.g. upgradeTo ) is typically implemented in the logic contract, not the proxy. The proxy delegates the call to this function.
This function is secured by a role-based access control or an owner check, ensuring only the authorized admin can trigger the upgrade, which points the proxy to a new logic contract address.
Glossar
Logic Contract
Foundation ⎊ A Logic Contract, within cryptocurrency and derivatives, represents a formalized agreement executed via smart contracts, defining the conditional transfer of assets or value based on pre-defined outcomes.
Access Control
Authorization ⎊ Access Control defines the granular permissions dictating which authenticated entities can perform specific operations within a decentralized application or network protocol, functioning as a critical security perimeter against unauthorized state modification.
UUPS Proxy
Deployment ⎊ UUPS Proxies represent a design pattern within smart contract architecture, facilitating upgradeability without redeployment of the core contract logic.
Uups Contract
Architecture ⎊ A Uups contract is defined by its specific architectural separation, consisting of a lightweight, immutable proxy that holds the contract's state and a separate, upgradeable implementation contract containing the business logic and the upgrade mechanism.
Upgrade
Iteration ⎊ An upgrade, within cryptocurrency, options trading, and financial derivatives, signifies a protocol or system evolution, often implemented through hard forks or soft forks in blockchain technology, impacting consensus mechanisms and smart contract functionality.
Upgrade Function
Method ⎊ The upgrade function is the specific, highly privileged method responsible for atomically changing the address of the implementation contract that a proxy delegates its calls to.
