Liquid Network Exploited for 4,000 BTC in Alleged White-Hat Hack

Key Facts

1Alleged white-hat hackers withdrew approximately 4,000 BTC, worth $320 million, from Liquid Network federation reserves.
2The sidechain was paused and bridge nodes disabled following the exploitation of an inflation bug in L-BTC.

Amid escalating concerns over the security of blockchain scaling solutions, the Liquid Network has suffered a major exploit resulting in the withdrawal of approximately 4,000 BTC, valued at $320 million. According to reports, hackers exploited an inflation bug in the L-BTC sidechain, allowing them to create unbacked assets and trigger a valid peg-out transaction from the federation's reserves. In response, the sidechain has been paused and bridge nodes disabled to prevent further unauthorized activity.

This security failure highlights the vulnerabilities inherent in federated sidechains, as treasury reserves reportedly dropped from over 4,200 BTC to just over 207 BTC following the incident. Per analyst data, the attackers left an on-chain message identifying themselves as white-hat hackers and requesting contact. While this suggests the potential for a return of funds, the exploit represents a significant technical breach for the Blockstream-founded network and its multisig security model.

Traders should watch for updates regarding the recovery of funds and the permanent fix for the L-BTC inflation bug, as market sentiment remains sensitive to such large-scale security breaches (as of close September 7, 2026). With no major crypto-specific catalysts in the immediate economic calendar, the focus remains on official statements from the Liquid federation regarding the resumption of bridge services and the status of retail user holdings.
