Token Incentives — Volume-Based PUMP Token Rewards

Implement and maintain the token incentive system that rewards traders with PUMP governance tokens based on their SOL trading volume, using a day-based epoch system with pro-rata distribution.

Context

The Pump protocol incentivizes trading activity by distributing PUMP tokens to users proportional to their SOL trading volume. The system tracks volume in day-long epochs, with each day having a pre-configured token supply pool.

Day-Based Epoch System

Volume tracking operates in fixed-length epochs defined by the GlobalVolumeAccumulator:

• startTime — epoch system start timestamp
• secondsInADay — epoch length (typically 86,400 seconds)
• solVolumes[] — array of total SOL volume per day
• totalTokenSupply[] — array of PUMP tokens available per day

dayIndex = Math.floor((currentTimestamp - startTime) / secondsInADay)
