Our verdict
Komainu is a custodial software vault for institutions rather than a personal wallet, and it suits exchanges, funds and market makers that want a regulated provider holding the keys. It pairs MPC and HSM wallet architectures with registrations in GB and AE and lists from 6,000 coins supported.

Safety and regulation
Komainu takes a custodial approach, meaning the keys are held for the client rather than by the client. The custody architecture is described as MPC and HSM wallet architectures, so signing is shared across parties and dedicated hardware rather than resting on one exposed machine. The firm appears on the UK Financial Conduct Authority register, 985974, and holds a Dubai Virtual Assets Regulatory Authority licence, 2189.
Who runs it
The provider is Komainu Holdings Limited, a firm founded in 2018 and headquartered in the United Kingdom. It operates under the UK Financial Conduct Authority registration, 985974, and the Dubai Virtual Assets Regulatory Authority licence, 2189. Listed support runs on email, so firms wanting a phone line or live chat need to raise it during onboarding.

Frequently asked questions
Who holds the keys in a Komainu wallet?+
Komainu runs a custodial wallet, so the provider holds the keys and signs on the client's behalf. That suits firms wanting a managed vault with the security work handled for them, and it rules out anyone who needs to control and recover keys independently.
How many coins does Komainu support?+
The custody service lists from 6,000 coins supported, well above the wallet category median of 49. That spread suits an exchange or fund holding a long tail of assets rather than a handful of major coins.
Is Komainu regulated?+
Yes. Komainu is on the UK Financial Conduct Authority register under 985974 and holds a Dubai Virtual Assets Regulatory Authority licence, 2189. Buyers in GB and AE can point to a named regulator on the record.
How is the vault protected?+
The custody setup is built on MPC and HSM wallet architectures, which spreads signing across multiple parties and dedicated hardware instead of one machine or one exposed key. Paired with the custodial model, the security burden sits with the provider rather than the client.
How do I get help from Komainu?+
Support runs on email only, with no phone line or live chat listed. Urgent problems therefore travel by written reply rather than a live conversation, and larger firms may want a named relationship contact agreed during onboarding.
Who runs Komainu?+
The service is provided by Komainu Holdings Limited, founded in 2018 and headquartered in the United Kingdom. Institutional buyers usually check the contracting entity and its regulatory status before onboarding, and those details are all on the public record.
Is Komainu a self-custody wallet?+
No. Komainu is custodial and operates as a software wallet, so the provider controls signing. Nebeus by contrast is self custody. The decision rests on whether a regulated provider should hold the keys for you.
