Гаманець для Kusama

What is Kusama (KSM)?

Kusama runs Polkadot's code without Polkadot's caution. It is the same software on a separate network, used as the place where upgrades, parachain and coretime mechanics and governance changes are tried under real economic conditions before they reach Polkadot. Fees are real, mistakes are real, and there is no central switch to undo them.

For a holder, KSM behaves unlike an ERC-20 in a few ways worth knowing:

• KSM pays its own transaction fees. There is no second asset to top up and no token contract behind the balance.
• A Kusama account has an existential deposit. Sweep the balance down to almost nothing and the account is removed along with the remainder, so leaving a small amount behind is the normal habit.
• Addresses use Kusama's own SS58 prefix, so the same key produces a Kusama address that looks nothing like its Polkadot counterpart even though the underlying account is derived identically. A Polkadot-formatted string is not where KSM should be sent.

Much of what people do with KSM - nominating validators, voting, waiting out an unbonding period - involves signing rarely and then leaving the account alone for weeks. A Tangem card matches that rhythm: the key is created inside the card's secure element and never leaves it, each extrinsic is authorised by a tap, and between taps the card is an object in a drawer rather than software that has to stay installed and updated. Holding KSM that way keeps a long, mostly idle account reachable without keeping it exposed.
