Гаманець для Wrapped Minima

What is Wrapped Minima (WMINIMA)?

Minima's whole idea is that the node is small enough to run on a phone or an IoT device, so every participant constructs and validates rather than trusting someone else's server. Native MINIMA is the coin on that network, and it only exists inside it. WMINIMA is a separate thing: an ERC-20 issued on Ethereum, created so the asset could be held and traded with standard Ethereum infrastructure without anyone having to run a Minima node first.

That distinction is the one that catches people. Holding WMINIMA in an Ethereum wallet gives you the asset but no presence on the Minima network - no node, no participation in validating it. What you have is an Ethereum token in every respect: it sits at an Ethereum address, appears next to your other ERC-20s, and every transfer costs ETH, which needs to be in the same wallet.

Supported networks in Tangem (1): Ethereum.

Tangem creates the key in the card's chip and does not let it out; the card signs when you tap it, and a second card from the set is the way back in if the first one goes missing, with a recovery phrase available only if you want one. For an asset you may hold quietly for a long time, that arrangement holds up.
