Hackers drained $320 million in bitcoin from a Layer 2 solution, then claimed they were acting as white hats.
What happened
Roughly $320 million worth of bitcoin was taken from a bitcoin Layer 2 scaling solution. The perpetrators called themselves white-hat hackers and asked the project to contact them on chain. The broader crypto market shed roughly $500 billion in value on the day.
Why it matters
A Layer 2 is supposed to inherit bitcoin's core security while making transactions faster and cheaper. A breach this large breaks that promise. It puts every protocol that relies on similar bridging or staking logic at immediate risk of copycat attacks, and chills fresh capital from entering the space until the vulnerability is proven fixed.
The case against
A white-hat claim, if true, means the funds were taken to expose a flaw so the team could patch it before a real thief struck. The $500 billion market drop could be a short-term panic rather than a permanent loss of trust, and a clean return of all funds would restore confidence.
What settles it
Whether the funds are returned in full and the project publishes a clear technical post-mortem of the exploit path.
