# Struct Events ⎊ Area ⎊ Greeks.live --- ## What is the Notification of Struct Events? Struct events in Solidity are a mechanism for contracts to log information on the blockchain about specific actions or state changes involving struct instances. When a function modifies a struct, an event can be emitted, containing relevant data from the struct's fields. These events are not stored on-chain directly as state but are recorded in transaction logs, which are accessible off-chain. They serve as a crucial notification system for external applications, such as user interfaces or analytics dashboards. This provides transparency into contract operations. ## What is the Monitoring of Struct Events? Emitting struct events is vital for effective monitoring of smart contract activity, especially for complex financial derivatives. Traders and auditors can subscribe to these events to track changes in positions, collateral levels, or derivative contract parameters in real-time. For instance, an event could log the creation of a new OptionTrade struct or updates to a LiquidationStatus struct. This enables robust off-chain analysis, risk management, and compliance checks. Comprehensive event logging supports the sustainable auditability and transparency of DeFi protocols. ## What is the Auditability of Struct Events? Struct events significantly enhance the auditability of smart contracts and their interactions with structured data. By providing an immutable, chronological record of state changes related to structs, auditors can reconstruct the history of any financial instrument or user position. This transparent trail is invaluable for debugging, dispute resolution, and regulatory compliance. The ability to verify all relevant data points for a struct through events reinforces the trust model of decentralized finance. It is a cornerstone for building resilient and accountable financial systems for the long term. --- ## [Struct](https://term.greeks.live/definition/struct/) A custom data type grouping related variables together for efficient and organized data management in smart contracts. ⎊ Definition ##
