#BTC Recently, a technical security incident occurred on the BTC sidechain Liquid Network. According to publicly available on-chain data, during the period from September 6 to 7, the network experienced approximately 4,000 BTCc in abnormal transfers.

After the incident, the Liquid Network operators quickly paused network operations and began investigations together with multiple partner institutions. According to the latest reports, 3,400 BTC from the transferred assets have already been returned, with a recovery rate of over 85%. However, around 598.5 BTC have not yet been returned, and the relevant parties are handling the matter further.

The operators stated that this incident was caused by a technical vulnerability in the open-source software Elements, not the exposure of private keys. The attacker claimed to be a "security tester" and demanded that the vulnerability be fixed first before the assets were returned. After the vulnerability was patched, most funds were returned as agreed. However, some industry participants have raised questions about how the remaining funds will be handled, saying their actions are controversial, and the discussion is still ongoing.

Liquid Network is a BTC layer-2 settlement network jointly used by multiple trading platforms and financial institutions. This incident has a relatively broad impact. The network is still suspended; all platforms have paused the deposit and withdrawal services for the relevant tokens while awaiting further announcements.

Worth noting is that in the first half of 2026, the global crypto-assets sector has seen an increase in abnormal fund incidents caused by security vulnerabilities, with a cumulative amount involved reaching several hundred million dollars. This serves as a reminder to investors and market participants that when engaging in virtual-asset-related businesses, they must fully understand technical risks, choose compliant channels, and manage asset diversification.
