Root + Impact

Under normal behavior, events should be emitted during critical state changes (e.g., reward distribution or fee collection) so that off-chain systems (indexers, frontends, analytics) can track protocol activity accurately.

• In the current implementation, the SnowEarned and FeeCollected events are not emitted in their respective functions, despite state changes occurring. This leads to missing data for off-chain consumers that rely on events for accounting and tracking.

Risk

Likelihood:

• Occurs on every execution of reward distribution or fee collection functions

• Affects all off-chain systems relying on event logs (subgraphs, indexers, frontends)

Impact:

• Off-chain accounting becomes incomplete or incorrect due to missing event data

• Analytics, reward tracking, and user-facing dashboards fail to reflect actual protocol activityProof of Concept

Recommended Mitigation

Emit the respective events from the respective function calls for tokens earned and fees collected
