Hyperliquid founder Jeff Yan revealed that API server issues posed a significant challenge in 2025 as Bitcoin prices soared past $100,000. During this period, Hyperliquid's monthly trading volume exceeded $400 billion, leading to server struggles as market makers connected to the blockchain. The influx of institutional activity resulted in order execution delays of up to three seconds, a critical issue in high-frequency trading environments. Despite the server challenges, the blockchain remained operational and user funds were secure. Yan described the period as highly stressful, with frequent system failures disrupting his sleep. To address the problem, Hyperliquid's team undertook a complete server system overhaul, which successfully handled subsequent market pressures.
