Jihoz.ron has been at the center of two major security events in the Sky Mavis ecosystem. In March 2022, the Ronin Network bridge was exploited for approximately $625 million (173,600 ETH and 25.5 million USDC), an attack the FBI attributed to North Korean hackers. Sky Mavis subsequently raised $150 million led by Binance in April 2022 and fully reimbursed affected users before reopening the bridge. In February 2024, two of Zirlin's personal Ronin wallets were compromised, resulting in the theft of approximately 3,248 ETH (around $9.7 million), with the stolen funds moved through Tornado Cash. Zirlin publicly confirmed the breach was limited to his personal wallets and did not affect Ronin chain operations or Sky Mavis. Jihoz.ron was previously a Venture Partner at 1kx.
