In the ever-evolving world of Solana's decentralized exchanges, where meme tokens thrive and trading happens at lightning speed, a notable shift has just occurred. According to a recent post from SolanaFloor on X, Orca has reclaimed the throne as the top Solana DEX by 7-day trading volume, surpassing the up-and-coming HumidiFi.

The data highlights Orca leading with an impressive $5.983 billion in volume across two chains, followed closely by HumidiFi at $5.407 billion on one chain, and Meteora rounding out the top three with $4.34 billion. This overtake marks a significant moment, especially considering HumidiFi's meteoric rise earlier this year.

For those new to the scene, a DEX, or decentralized exchange, is a platform built on blockchain technology that lets users trade cryptocurrencies directly with each other without needing a central authority like a traditional bank or exchange. Solana's low fees and high speed make it a hotspot for these platforms, particularly for trading volatile meme tokens that can skyrocket or plummet in hours.

HumidiFi burst onto the scene in 2025 as a proprietary automated market maker (AMM), quickly climbing the ranks thanks to its innovative vault-based liquidity model. In fact, it became one of the top Solana DEXs by volume in under three months, capturing a massive share of trades through aggregators like Jupiter.

Orca, on the other hand, is a more established player in the Solana ecosystem. Known for its user-friendly interface and features like concentrated liquidity pools (called Whirlpools), it has long been a go-to for traders seeking efficient swaps. This recent surge in volume could be attributed to increased adoption, perhaps driven by new integrations or a rebound in overall Solana activity amid the meme token craze.

What does this mean for meme token enthusiasts? Higher trading volumes on Orca might translate to better liquidity for popular memes, reducing slippage—the difference between expected and actual trade prices—and making it easier to jump in and out of positions. If you're trading tokens inspired by internet culture, animals, or viral trends, keeping an eye on DEX rankings like this can help you spot where the action is hottest.

This development also underscores the competitive nature of Solana's DeFi space. With platforms like Meteora still holding strong, and others like Raydium and Pump.fun in the mix (as seen in broader DeFiLlama data), the battle for dominance is far from over. Traders should monitor these shifts, as they often signal broader market trends or upcoming features that could boost specific DEXs.

As Solana continues to dominate in DEX volumes—extending its lead over Ethereum with surges like the 56% jump in July 2025, per CoinTribune—events like this Orca overtake highlight why the network remains a powerhouse for meme token innovation and trading.
