A tiny cluster of Solana bots unlocked a 3x trading advantage by routing through one proprietary protocol

A notable development has hit the crypto markets. New research into automated trading on Solana found a nearly threefold difference in positive wrapped SOL outcomes inside one small group of bots. Transactions that invoked HumidiFi, which the paper classifies as a proprietary automated market maker, recorded a positive WSOL balance change about 62. Other transactions in the same 12-address group did so at a 21.

The comparison covered 244,733 HumidiFi-invoking transactions, including 152,502 with a positive WSOL balance change, and 218,678 other transactions, including 45,949 with a positive change. The rate ratio was about 2. The edge appeared in one narrow cluster The ASE 2026-accepted paper examined 200 addresses associated with two trading-oriented bot services on the Solana network.

Market Dynamics

The researchers selected the top 100 addresses linked to Trojan and the top 100 linked to SolanaMevBot, then collected their transactions from Oct. They grouped 158 addresses into four clusters using measures such as transaction intensity, execution success, fees, and asset breadth, while treating 42 addresses as noise. The paper also studied 586 public bot repositories, but that software sample was built separately and cannot be connected to the 200 on-chain addresses.

Its authors published a replication package through Zenodo. Transaction-pattern reviews and service labels supported treating three clusters, totaling 56 addresses, as MEV-like. In this context, that meant the bots showed round-trip, cross-venue trading patterns consistent with arbitrage.

94% of transactions across those groups, but each cluster used a different venue mix. The 12-address group at the center of the profit-rate comparison routed heavily through Jupiter and also invoked proprietary AMMs including HumidiFi. The researchers identified venues from the programs called inside each transaction and mapped those program IDs using Solscan annotations.

Market Impact

They said the routes may involve closed or specialized liquidity, but did not determine why the HumidiFi-linked transactions performed differently.

It was not a fully netted account of strategy returns that isolated fees, tips, timing, address behavior, route choice, or other potential differences. The data show a correlation within this cluster, not proof that HumidiFi access caused the gap.

This shift continues to shape the digital-asset landscape, with analysts examining its near-term effects.
