How It Works & Key Formulas (Quick Reference)

Technical figures, mathematical formulas, and verified on-chain mechanics.

Pump.fun implements a constant product automated market maker formula k = x * y, where virtual token reserves are initialized at 1,073,000,000 (1.073B tokens) and virtual SOL reserves are initialized at 30.0 SOL, creating an invariant k = 32,190,000,000.
