Singleton Contract

Definition

A singleton contract is a smart contract designed to have only one instance deployed on a blockchain. This architectural pattern ensures that a specific set of functionalities or a particular data store exists as a unique, globally accessible resource within the blockchain ecosystem. It prevents the deployment of multiple, conflicting versions of the same core logic or state, maintaining consistency and simplifying interactions for other contracts and users. Singleton contracts are often employed for critical infrastructure components, such as registry services or central governance modules.
