Tangem is a Swiss provider of card-shaped hardware wallets that offer top security (EAL6+) as well as unparalleled simplicity of onboarding and use. Ours was the first hardware device to support Kaspa. As of now, we have produced two Kaspa-branded versions of our cards in close cooperation with the community.
