In the fast-paced world of Solana's DeFi ecosystem, a major shift is underway. Last week marked a historic moment as Proprietary Automated Market Makers (Prop AMMs) handled over 50% of the decentralized exchange (DEX) volume on the Solana blockchain. This insight comes from a recent post by Dan Jablonski, a key figure in the space, highlighting a weekly volume exceeding $13.2 billion. For meme coin enthusiasts and blockchain practitioners, this signals exciting changes in how trades happen on-chain.

The chart from Blockworks Research illustrates this trend clearly. Starting from May 2025, we see the purple segment—representing Prop AMMs—steadily growing, overtaking traditional models like Constant Product (yellow) and Concentrated Liquidity (gray). By mid-September, Prop AMMs claimed 50.7% of the volume, with Constant Product at 31.7%, and others trailing behind. This isn't just a blip; it's a sign of evolving on-chain liquidity.

What Are Prop AMMs?

If you're new to this, let's break it down. Traditional AMMs, like those on Uniswap or Raydium, use open pools where anyone can provide liquidity. Prices adjust based on simple formulas, such as the constant product model (x * y = k). Prop AMMs flip the script. They're proprietary, meaning the trading logic is embedded directly into Solana programs and managed by specialized market makers. This allows for active liquidity management—think real-time price adjustments based on sophisticated strategies, all happening on-chain without the delays of off-chain servers.

Key benefits include tighter spreads (the difference between buy and sell prices), lower slippage (how much a large trade moves the price), and better protection against maximal extractable value (MEV), where bots front-run trades. Examples of Prop AMMs making waves on Solana include Lifinity, SolFi, Obric, and HumidiFi. These platforms have captured massive volumes, with some handling over 60% of trades in major pairs like SOL/USDC.

Why This Matters for Meme Tokens

Solana has long been the go-to chain for meme coins, thanks to its speed and low fees. Projects like Pump.fun and countless viral tokens thrive here. But trading them often involves DEXs with traditional AMMs, which can lead to high slippage during hype cycles. The rise of Prop AMMs could change that. By offering more efficient pricing and deeper liquidity, they make it easier to buy and sell meme tokens without getting rekt by poor execution.

Imagine launching a new meme coin and tapping into Prop AMM liquidity for smoother ramps. Or as a trader, getting CEX-like quotes directly on-chain. This paradigm shift, as Dan calls it in his X post, is all about optimizing "onchain flow"—the seamless movement of value in DeFi. For meme insiders, it's an opportunity to level up strategies, from sniping launches to holding through volatility.

The Bigger Picture in Solana DeFi

This milestone isn't isolated. Solana's ecosystem is booming, with aggregators like Jupiter routing over 40% of DEX swaps to these efficient venues. While Prop AMMs are closed-source, raising some transparency concerns, their performance is undeniable. They've reduced costs through innovations like low-compute oracle updates, making frequent price refreshes feasible.

As we head into the next bull cycle, keep an eye on how this affects meme token dynamics. Will more meme DEXs adopt Prop models? Could this draw in institutional liquidity, stabilizing wild swings? At Meme Insider, we're tracking these trends to help you stay ahead in the blockchain game.
