Solana Bots Enjoy 3x Trading Advantage with HumidiFi Protocol

A recent study on Solana's trading bots has shed light on an intriguing phenomenon. Researchers found that a small group of bots, totaling just 12 addresses, enjoyed a significant trading advantage by routing through a proprietary protocol called HumidiFi.

The study analyzed transactions from October 1 to November 1, 2025, and compared the results with other Solana transactions. The researchers discovered that transactions invoking HumidiFi recorded a positive WSOL balance change about 62.3% of the time, while other transactions in the same group achieved this rate at just 21.01%. This represents a nearly threefold difference in outcomes.

The researchers identified venues from the programs called inside each transaction and mapped those program IDs using Solscan annotations. They found that the routes may involve closed or specialized liquidity, but did not determine why HumidiFi-linked transactions performed differently.

While the study does not prove that access to HumidiFi caused the gap in outcomes, it suggests a correlation within this cluster. The researchers noted that the data reveal materially different conditions inside the sampled execution paths.
