A Watcher Contract is a type of smart contract designed to monitor specific events or conditions on a blockchain. Its main purpose is to execute actions based on observed data or triggered events, often in real-time.These contracts can watch transactions, token transfers, or changes in state. When the predefined criteria are met, the Watcher Contract can automatically trigger responses, such as executing another contract, notifying users, or performing transactions. This automation increases efficiency, as it removes the need for manual oversight and intervention. It also contributes to transparency, as the actions taken by the Watcher Contract are recorded on the blockchain, providing a clear audit trail. In essence, Watcher Contracts serve as vigilant observers that enhance the functionality of decentralized applications (dApps) by ensuring processes occur seamlessly and promptly based on real-time changes within the blockchain environment.
