New Solana RPC Targets HFT and MEV

Solana's high throughput and approximately 400ms block times have made it a primary venue for latency-sensitive operations. This speed creates a competitive environment where specialized infrastructure is necessary to effectively engage in high-frequency trading (HFT) and Maximal Extractable Value (MEV) extraction. RPC Fast enters a competitive landscape of Solana infrastructure providers, directly challenging established names like Triton One, known for its Yellowstone gRPC, and Helius, which focuses on enhanced developer APIs. The service is built on bare-metal servers, a choice aimed at providing stable p99 latencies and avoiding the performance variability of some cloud environments. The service’s focus on MEV is critical due to Solana's architecture. Unlike Ethereum, Solana lacks a public mempool, making MEV a game of speed and direct connectivity to block-producing validators. Low-latency data streams, such as Jito ShredStream or gRPC, are essential for bots to see transactions early and land arbitrage or liquidation transactions in the same or next block. This infrastructure approach mirrors modernization trends in traditional finance. The use of bare-metal servers instead of multi-tenant cloud infrastructure is a strategic decision for controlling performance, similar to how trading firms utilize co-location in exchange data centers to reduce network hops. While cloud solutions offer scalability for research and less latency-critical workloads, on-premises or dedicated hardware provides the raw performance needed for execution. The underlying technology for these low-latency systems often involves kernel bypass techniques like DPDK or RDMA.
