Exception handling refers to the process of managing errors or unexpected events that occur during transactions or interactions with blockchain networks and smart contracts. It ensures system resilience by allowing applications to respond gracefully to issues without crashing.In the context of blockchain applications, errors can arise from various sources, including incorrect input data, network failures, or issues within the smart contract itself. Implementing exception handling involves anticipating potential errors and defining specific responses to them.For example, if a smart contract tries to execute a transaction that exceeds available balance, effective exception handling will prevent the contract from failing and provide feedback, such as an error message. This can help users understand the issue and correct it.Good exception handling enhances user experience by providing clarity, minimizes potential losses by halting transactions that can’t be completed, and promotes security by preventing exploits that could compromise the system. Overall, it plays a critical role in maintaining stability and trust in decentralized applications and transactions.
