A security breach on the Liquid sidechain reportedly led white-hat hackers to take around 4,000 $BTC .
The Liquid Network paused the sidechain while its team investigated what happened and worked to recover the funds.
The incident came as bitcoin ETFs were enjoying their strongest three-week inflow streak of 2026, attracting roughly $3.8 billion - an encouraging stretch for the market, though the breach added an unwelcome dose of uncertainty.
