Komainu

What Komainu does

Komainu is a Jersey-headquartered, regulated digital asset custodian serving institutional clients including banks, asset managers, hedge funds, family offices, and cryptocurrency exchanges. Founded in 2018 as a joint venture between Nomura Holdings, CoinShares, and Ledger, the company operates regulated entities in five jurisdictions — Jersey (JFSC), Dubai (VARA), the United Kingdom (FCA), Singapore (MAS, via the Propine Holdings acquisition), and Italy (OAM) — and supports custody across more than 40 native blockchains and 6,000+ tokens. Its core technology combines Multi-Party Computation (MPC) and Hardware Security Module (HSM) wallet architectures with CC EAL5+ air-gapped signing devices, zero-trust security design, and SOC 1 Type II, SOC 2 Type II, and ISO 27001 certifications. The architecture is delivered off-balance-sheet with segregated wallets designed for bankruptcy remoteness and on-chain verifiability.

The product set is platform-plus-modules: core Custody; Komainu Connect, a collateral management platform integrating exchanges (OKX, Bybit, Gate.io, Bitfinex), prime brokers (Hidden Road), and derivatives venues (Deribit) so institutions can trade, borrow, and lend without pre-funding; custodial Staking across Proof-of-Stake networks including Lido stETH and Hyperliquid; and Komainu CORE, a Collateral-as-a-Service offering launched in April 2026 with enforceable asset locking, real-time LTV monitoring, whitelisted counterparty management, and a regulated liquidation framework. Clients access all services through the Komainu Portal (front-, middle-, and back-office) with API connectivity, plus Travel Rule integrations with Notabene, TRISA, and OpenVASP for cross-jurisdictional compliance.

Komainu's business model combines subscription-based custody fees, transaction-based fees on Connect and CORE, and revenue sharing on staking rewards, delivered through an enterprise sales-led motion targeting compliance officers and treasury teams at financial institutions, supplemented by channel partnerships with exchanges, prime brokers, and benchmark providers (notably Nasdaq crypto indices). The company has raised $100M cumulatively ($25M Series A in 2021; $75M Series B led by Blockstream in January 2025) and employs between 11 and 50 people across headquarters in St. Helier and offices in London, Dubai, Singapore, and Milan. It has won the Fortune Crypto Innovators recognition (2026), Hedgeweek Custodian of the Year EMEA and Innovation (2026), and Global Custodian Innovation in Digital Asset Custody (2025).
