Hong Kong's largest licensed virtual asset trading platform HashKey Exchange announces a deeper collaboration with OneInfinity, a brand under Asia's leading Web3 insurance service provider OneDegree, in partnership with several top international insurance companies to upgrade custody insurance solutions, setting a new high in insurance coverage scale and maintaining its position as the licensed virtual asset exchange with the largest insurance scale globally, further safeguarding users' investment interests.

After this upgrade, the custody asset insurance period for HashKey Exchange will reach 18 months, and its coverage will further expand, covering at least 50% of custody assets. This arrangement will significantly reduce platform asset risks and build a strong safety barrier for retail and institutional clients.

The insurance plan involved in this cooperation has set a global record in coverage scale. This insurance plan is provided by OneInfinity and supported by Arch Insurance International and other reinsurers with an AM Best 'A-' and Standard & Poor's (S&P) 'AA-' credit rating. Arch Insurance International is a significant underwriting member of Lloyd's of London, the world's most renowned insurance market.

Additionally, HashKey Exchange has optimized its custody structure through this cooperation, enhancing the security protection of core ecological assets, thereby making significant progress in overall risk management and risk mitigation.

Evertas is also one of the key insurers facilitating this upgrade, acting as an authorized underwriter by Lloyd's of London and collaborating with Elmore to facilitate the cooperation between OneInfinity, HashKey, and Arch Insurance International. The collaboration is based on a long-term mutually trusting relationship, laying the foundation for the robust development and continuous innovation in the digital asset industry.
