Summary

Hyperdrive HL (formerly Ambit Finance) is a stablecoin lending and liquid-staking protocol deployed on Hyperliquid EVM, which raised a $6 million Series A in May 2025 led by Hack VC and Arrington Capital. On September 27, 2025, an attacker exploited an arbitrary-call vulnerability in the protocol's router contract, draining approximately $782,000 in USDT0 and thBILL tokens across two markets. The team paused operations, patched the vulnerability, and compensated affected users before resuming, though the incident occurred within a broader wave of security breaches across the Hyperliquid ecosystem.
