{% docs fact_events %}

Description

This table records every event emitted by on-chain Solana programs during transaction execution. Each row represents a single event, including its type, the program that emitted it, and its position within the transaction. The table covers all events observed on Solana mainnet, including protocol-level and application-level activity. Events are uniquely identified by block, transaction, and event index. This model enables detailed analysis of program behavior, user actions, and protocol interactions at the event level, and is central to understanding the full scope of on-chain activity.

Key Use Cases

• Analyze program interactions and instruction execution flow
• Track specific program events, methods, or user actions
• Protocol usage analytics and event-level activity monitoring
• Avoid complex JSON array parsing from core.fact_transactions by using pre-parsed event fields
• Downstream analytics for protocol-specific event flows and decoded instructions

Important Relationships

• Closely related to core.fact_events_inner (for inner/CPI events), core.ez_events_decoded (preferred for decoded instruction details), and core.fact_transfers (for transfer events)
• Use core.fact_events_inner to analyze Cross-Program Invocations (CPIs) and nested program calls
• Use core.ez_events_decoded for detailed instruction and argument analysis (if program is being decoded)
• Use core.fact_transfers for asset movement and transfer analytics
• Joins with core.fact_blocks for block context and core.fact_transactions for transaction context

Commonly-used Fields

• block_timestamp: For time-series and event sequencing analysis
• block_id, tx_id, index: For unique event identification and joins
• program_id, event_type: For filtering by program or event type
• instruction, inner_instruction: For instruction-level analytics
• signers, succeeded: For user attribution and transaction outcome analysis
