Use events to log state changes, providing a reliable and efficient way to track updates and enhance transparency for off-chain monitoring.

cryptos

Description

Events provide a reliable way for off-chain systems and decentralized applications (DApps) to monitor and respond to contract updates without the need for costly on-chain polling. It is recommended to add events to the code to ensure that important contract actions can be easily tracked and responded to by external systems.

Impact

If the service has a front end, the client will be unaware of changes because the contract’s state is not indexed.

Recommended mitigation

Incorporating events into the smart contracts improves their integration with off-chain systems, allowing for efficient monitoring and tracking of state changes without requiring constant on-chain polling.

event CharityRegistered(address indexed charity);
