Hyperliquid founder Jeff was followed into the elevator, then moved out of the office and residence, and hired bodyguards.

Odaiy Cryptocurrency News Network: Hyperliquid Founder Jeff Yan and His Team Recently Featured in a Special Interview with Colossos Magazine.
During the interview, Jeff and another co-founder, iliensinc, discussed issues related to personal safety.
iliensinc revealed that Jeff is the only person on the team who does not use an alias.
Hyperliquid’s office was initially located in a shared workspace in the financial district, but as Jeff’s reputation grew, public attention increased.
At first, there were just some watchful eyes; some people tried to recognize Jeff’s face;
then strangers started approaching him proactively; later, someone followed him into the elevator of his apartment building.
As a result, Hyperliquid moved to a quieter location, a building where no one would think to look for them.
Jeff himself also moved to a safer residence, hired bodyguards, and has two private security personnel accompany him when traveling.
iliensinc also repeatedly trains team members on how to respond if strangers ask where they work.
