How pump.fun volume actually works
Volume on pump.fun is just buys and sells hitting the bonding curve. Here is the mechanism, why trending is volume-ranked, and how bots generate it safely.
The pump.fun bonding curve is a constant-product market (x·y=k) with a 1% fee per trade. Every buy nudges price up the curve; every sell nudges it down. Volume is simply the SOL value of those swaps over a window.
Trending boards rank largely on recent volume and trade count — not price. That is why a token with steady two-sided flow climbs while a flat one disappears, even at the same market cap.
A volume bot like Vol Bot creates that flow with many small, two-sided trades from a fleet of wallets. Micro-trades round-trip for roughly a 2% curve-fee cost while multiplying displayed volume many times over.
The craft is looking organic: varied sizes, timing and wallets, with buys and sells roughly balanced so you are not simply dumping. That is exactly what the boss/worker engine automates.
