Most crypto cards let you spend volatile assets and charge you a spread for the privilege. Kast starts from stablecoins, which removes the largest cost in this category before it arises.
Why stablecoin-first matters
Converting BTC or ETH at the point of sale means crossing a spread on a volatile asset, typically the biggest single cost of using a crypto card. Holding and spending a stablecoin balance reduces that to a small conversion into local currency. Kast's design assumes that workflow rather than offering it as an advanced option.
Coverage and rewards
Available across a wide international footprint including markets that European and US providers do not serve, with tiered card products and cashback that is competitive at higher tiers.
The company
Founded in 2024, with limited public disclosure about issuing partners, licensing and how balances are held. That is the standing concern with every new entrant in this category, and it is the reason for the issuer-stability mark of 5.
Who should use it
Users wanting cheap stablecoin spending in markets with few alternatives, holding minimum working balances. Users with access to Gnosis Pay, Coinbase or a regulated European issuer should prefer those.
