Our take
Bybit Card
The Bybit Card functions as a practical bridge between custodial exchange balances and global Mastercard retail payment rails. Issued primarily as a debit card linked to the Bybit funding account, the card simplifies off-ramping digital assets by automating fiat conversions at checkout. The product accommodates major cryptocurrencies alongside stablecoins and regional fiat, allowing cardholders to spend balances directly without manual pre-conversion orders.
While the card offers streamlined digital wallet integration and attractive VIP reward point ladders, cardholders encounter specific operational expenses. Transactions involving crypto conversion incur a direct zero point nine percent liquidation fee in addition to underlying spot market rates, plus foreign exchange markups on non-local spend. For active traders maintaining working capital within the Bybit ecosystem, the card delivers reliable payment convenience, provided users account for regional eligibility restrictions and network conversion layers.
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.
