How DFlow Uses LaserStream to Quote Solana's Best Prices

Solana’s North Star is a decentralized Nasdaq, and by every observable metric, the network is making this promise a reality, evidenced by capturing 80% of global on-chain DEX volume in 2024 and exceeding $890 billion in the first half of 2025.

However, with Solana’s rapid growth comes increased competition. With the median on-chain bid-ask spread for the SOL/USDC pair across Prop AMMs consistently sub-1bps, trading venues are racing to offer the tightest spreads, deepest liquidity, and win more order flow.

To compete at the highest level, teams like DFlow, a low-latency DEX aggregator, are building sophisticated platforms for trading venues and market makers to offer more competitive on-chain quotes, realize more trading volume, collect more trading fees, and improve yields on providing liquidity.

Over the past quarter, DFlow has surpassed $2 billion in trading volume within a single 30-day period, reflecting more than 5X growth compared to the previous quarter.

This milestone highlights not only the robustness of DFlow’s aggregation architecture but their ability to handle institutional-scale RFQ demand with ultra-low-latency performance.

This article will explain how DFlow quotes Solana’s most competitive prices and how they use LaserStream to power their pricing engine.

What is DFlow and how does it work?

DFlow is a low-latency DEX aggregator built exclusively for Solana trading applications and on-chain market makers.

DFlow synthesizes raw on-chain state from multiple liquidity venues like AMMs (e.g., PumpSwap), CLMMs (e.g., Raydium), DLMMs (e.g., Meteora), Prop AMMs (e.g., SolFi, HumidiFi), and CLOBs (e.g., Phoenix), to construct a live price graph. DFlow’s real-time price graph enables them to generate atomic quotes.

DFlow services flow from their frontend as well as through wallet integrations, and DeFi apps that demand the best prices, tightest spreads, and lowest latency routes, such as Phantom, Kamino, and Jupiter.

Using DFlow’s Swap API, integrators and trading desks request quotes from DFlow’s unified liquidity graph and submit swaps across all of DFlow's supported venues.

By integrating with DFlow’s single Swap API, integration partners:

• Can execute large orders with minimal market impact
• Dynamically split trades across venues based on real-time quote quality
• Get access to tight spreads and deep on-chain liquidity across every supported venue 

How does DFlow deliver the best quotes?

At the source of DFlow’s streaming price graph is its real-time data ingestion pipeline powered by LaserStream. DFlow streams everything that on-chain activity produces — every block, transaction, and account update — then indexes the raw account state of the DEXs, and builds a price graph for each market they serve, including:

• Majors (e.g., SOL/USDC)
• Blue-chips (e.g., JTO/USDC)
• Memecoins (e.g., BONK/USDC)
• Long-tail assets (e.g., newly or pre-graduated Pump or Bonk tokens)

Unlike other DEX aggregators and routers that rely on external, third-party oracles, DFlow calculates prices directly using exclusively on-chain data emitted by the network. 

Because even millisecond-level lag can widen spreads enough to make quotes uncompetitive, DFlow’s ingestion pipeline ensures that each price calculation reflects the freshest, most accurate on-chain state.

Faster trading data means fresher token price graphs, more competitive buy-sell quotes, and better protection for liquidity providers and end users from adverse selection.

How does DFlow use LaserStream to maximize performance?

Before switching to LaserStream, DFlow ran dedicated nodes running Yellowstone's open-source gRPC client with custom consumption patterns, and they were regularly spending 8+ hours a month maintaining their nodes.

The decision to migrate to LaserStream came down to two things:

1. The ability to scale globally without worrying about Solana node capacity
2. Saving engineering bandwidth to focus on business code

During the evaluation process, DFlow compared LaserStream with dedicated nodes. After extensive testing during the private beta, they confirmed LaserStream was faster, more reliable, and more scalable than running multiple gRPC nodes around the world.

With LaserStream’s seven global endpoints, extreme redundancy, and optimized ShredStream delivery, DFlow consistently outperforms dedicated nodes while simultaneously reducing overhead.

The results?

Since migrating to LaserStream, DFlow:

• Eliminated 8+ hours of recurring engineering overhead
• Maintained 100% uptime and uninterrupted data streaming
• Improved quote speeds with faster transaction confirmations
• Achieved one of the single best months of swap volume in protocol history

Thanks to LaserStream’s global cluster of redundant nodes, ultra-low latency data streams, automatic reconnects, and historical replay, DFlow can offer more competitive quotes while reducing their engineering overhead.

Essential Trading Infrastructure for Solana DeFi

LaserStream isn’t simply an optimization—it is foundational streaming infrastructure that every latency-sensitive DeFi application on Solana needs to compete at the highest level.

With Solana’s ambitious CU increases, the upcoming Alpenglow consensus upgrade, and DEX-to-CEX trading volume sitting above 20%, on-chain transaction volumes are accelerating.

To offer the best quotes, lowest-latency routes, and win order flow, Solana DeFi teams need a data streaming solution capable of keeping up with Solana’s speed and throughput.  

LaserStream is the fastest, most reliable way to receive on-chain market updates. No more dedicated nodes. No more disconnections. Simply unparalleled performance.
