About Komainu

Read full description
The business operates in the growing digital asset market, where the need for secure and regulated custody solutions is paramount. Komainu's business model is centered on providing custody services, likely charging fees based on the amount of assets under custody (AUC) and transaction volumes. By leveraging the expertise of its founding partners, Komainu combines traditional financial services standards with blockchain technology.
The platform is designed to be a third-party custodian, independent of its clients' trading activities, which helps to mitigate counterparty risk. This segregation is a key feature for institutional clients who require a high level of security and regulatory compliance. Komainu is regulated by the Jersey Financial Services Commission (JFSC), which provides a layer of oversight and ensures that the company adheres to strict operational standards.
