Dflow Blocks HumidiFi Routing as Walled Gardens Emerge in Solana DeFi

A swap routing block is raising eyebrows across Solana DeFi this week. Dflow, Solana’s second-largest DEX aggregator, has reportedly stopped routing trades to HumidiFi, a leading prop AMM.

The alleged block comes amidst a changing of the guard in the prop AMM game. While previously dominated by HumidiFi, emerging competition amongst prop AMMs is reducing reliance on the market leader.

Could Dflow’s alleged block signal the beginning of a network-wide shift towards siloed economies?

Dflow Swaps Cease Routing to HumidiFi

Since January 28th, swaps initiated from the Dflow aggregator have stopped being routed to HumidiFi, Solana’s leading prop AMM by daily trading volume. 

While analysts were initially uncertain as to which protocol was blocking the other, the HumidiFi 𝕏 account has since confirmed that the block originated from Dflow. Further posts suggest that the prop AMM has already requested that Dflow reintegrate HumidiFi routing, with Dflow yet to make a statement on the above claims.

At press time, DFlow has not responded to a request for comment.

Are Aggregators Picking Sides?

Dflow’s ongoing block comes as competition between Solana’s prop AMMs reaches a fever pitch. After consistently dominating Solana DEX volumes since August 2025, HumidiFi’s reign is being challenged by BisonFi, an emerging competitor.

In recent weeks, HumidiFi and BisonFi have routinely traded the top spot in Solana DEX rankings, with each protocol briefly holding the lead before being promptly eclipsed by its rival. 

While BisonFi is currently ahead in weekly volume share, HumidiFi appears to have reclaimed its crown over the last few days, commanding over 42% of daily volume according to Blockworks data.

In the absence of a statement from Dflow regarding the block, one could speculate that this move could mark the beginning of a new trend of favoritism among aggregators. Aggregators have historically routed trades to all AMMs, but Dflow’s selective routing could set a precedent for other aggregators to follow.

DFlow founder Nitesh Nath has previously highlighted that BisonFi’s first trades were routed through the aggregator, suggesting that the team may have a close relationship with the emerging prop AMM. 

Conversely, HumidiFi is known to have a close relationship with Jupiter, Solana’s leading aggregator by a considerable margin. Alongside hosting the ICO for HumidiFi’s native token, $WET, Jupiter’s validator also runs the Harmonic client, which is operated by HumidiFi’s parent company, Temporal.

However, as much as the Solana community loves onchain competition, be it aggregator wars, blockbuilding wars, or the launchpad wars of 2025, such enshrinement would only result in a diminishing experience for the end user. 

Prop AMMs are undoubtedly an incredible vehicle for capital efficiency, but the formation of siloed trading stacks would only fragment liquidity across the onchain economy. While benefiting individual operators, this would likely result in poorer trade execution for the average DeFi participant. 

Given Solana’s culture of high performance, it is unlikely that the chain’s DeFi scene follows this path.

Over 400 Apps Building on Dflow Prediction Markets

Outside of traditional token swaps, DFlow is gaining momentum as Solana’s first choice for prediction market composability. Since integrating its tokenized prediction markets directly into the Phantom Wallet UI, DFlow has become Solana’s largest hub of PM trading activity.

Speaking at Solana Accelerate Hong Kong, DFlow Director of Growth Dan Jablonski announced that over 400 applications are now leveraging DFlow’s Prediction Market API.

However, despite DFlow’s dominance of Solana’s nascent prediction market scene, Jupiter may still have an ace up its sleeve. At Catlumpur, Jupiter’s annual conference, it was announced that Polymarket, the world’s leading prediction market by volume, was expanding to Solana and would be accessible directly through Jupiter. 

Jupiter co-founder Meow has indicated that Jupiter Predict will be a key focus of growth throughout 2026.
