More than half of Solana's decentralized exchange trading volume comes from bots and circular trades, a new analysis shows. This raises doubts about real liquidity and whether headline numbers reflect what users and investors actually get.
Solana's decentralized exchange (DEX) scene is facing tough questions. A forensic review of trading shows that much of the reported volume comes from automated bots and circular trades, not from real users looking for genuine market liquidity. These findings call into question how deep and accessible Solana's DEX markets really are for everyday traders.
Automated activity dominates
Bitquery detected 123.6 million dust-sized trades across six chains, with 87% of these micro-trades occurring on Solana and 90% under $5 in value, highlighting the scale of bot-driven activity.
Volume metrics under scrutiny
This analysis shows a big problem with using total DEX trading volume as a stand-in for user demand or market health. DefiLlama's Solana DEX dashboard showed $75.9 billion in rolling 30-day volume as of September 24. But Bitquery's flagged activity suggests that much of this volume may not be available to independent traders at fair prices. Bitquery's approach looks at transaction patterns and wallet behavior, not just pool balances or unique addresses. This shows how headline numbers can be skewed by repeated, non-economic trades. Some pools that look busy on turnover tables are actually dominated by a few wallets trading the same assets back and forth, leaving little real liquidity for outsiders.
Liquidity and execution risks
For users, this means that reported DEX volume on Solana can give a false sense of how much real liquidity is there for meaningful trades. Neither Bitquery's nor DefiLlama's dashboards show how much an independent trader could actually buy or sell without moving the price a lot. Pools with big historical volumes can be empty when a new user shows up, as seen in the Claude/SOL pool case. To know the real liquidity, you'd need detailed data on past reserves, trading routes, and actual fills-data that volume totals alone don't provide.
Comparisons and limitations
Solana DEX weekly activity reached approximately 208 million spot trades for the week ending September 13, 2026, a figure that rivals traditional exchanges like the New York Stock Exchange in trade count, though not in dollar volume. This highlights the importance of distinguishing between transaction count and substantive liquidity when evaluating on-chain activity.
Bitquery says that from August 24 through September 22, it analyzed $201.4 billion in Solana DEX trades and flagged $117.7 billion as circular or botlike. DefiLlama's dashboard showed $75.9 billion in rolling 30-day volume as of September 24, but the two use different methods and pool lists, so the numbers don't match up. In one flagged case, a single transaction created $2,000 in volume in a pool that later had no real liquidity. This shows how headline numbers can mislead users about actual trading chances.
Circular trading and bot-driven volume are ongoing problems for decentralized exchanges. On-chain data can show trading patterns, but it doesn't always separate real user activity from automated strategies that pump up metrics or chase incentives. For traders and investors, high reported volume does not mean deep or accessible liquidity. To judge a DEX's real usability, you have to look past the surface numbers and ask who is trading, how trades are done, and whether liquidity is actually there when needed. As DEX platforms fight for users and capital, being open about these issues will be key to building trust and lasting growth.
