Our take
Changelly
Changelly operates as an instant non-custodial crypto swap platform and fiat on-ramp aggregator. The service routes digital asset exchanges directly between external wallets without holding customer deposits in platform balances. Users gain access to hundreds of blockchain assets through both floating market rates and fixed conversion quotes. However, total transaction expenses include network gas charges, conversion fees, and variable spreads from external payment providers. Automated transaction monitoring engines can also freeze incoming transfers if address risk thresholds trigger compliance flags. Traders seeking advanced charting or spot limit order books will find the simplified interface focused purely on direct conversions.
Komainu
Komainu delivers institutional digital asset custody designed specifically for fund managers, financial institutions, and corporate balance sheets. Founded in 2020 as a joint venture between Nomura, digital asset manager CoinShares, and security infrastructure developer Ledger, the platform bridges traditional financial compliance with native blockchain architecture. By leveraging modified Ledger hardware security modules alongside custom firmware, Komainu eliminates single points of failure across private key storage while maintaining strict segregation between client assets.
The platform excels at resolving counterparty risk through its Komainu Connect framework, allowing institutional traders to post collateral to trading venues without moving underlying assets out of regulated cold custody. While high asset minimums, bespoke legal contracting, and deliberate operational signing delays make Komainu unsuitable for retail users, it remains an exceptionally robust custodial infrastructure provider for institutional capital allocation.
