Undeads Games wallet

What is Undeads Games (UDS)?

UDS belongs to an open world survival MMORPG built for Web3, where the ambition is a full game first and blockchain plumbing second. The token is the economic layer around it rather than the game itself: it is held on Ethereum as a standard ERC-20, while characters, equipment and other in-game items are separate on-chain assets with their own contracts.

That split is the thing to understand before choosing a wallet. Three different objects get confused with each other in games of this kind: the UDS token, the non-fungible items, and any soft currency that only exists inside the game client and never touches a chain at all. Only the first two leave the game. A game account and a wallet are also different things; the wallet is connected to the account, and disconnecting it does not move anything out of it.

Because UDS sits on Ethereum, every outgoing transfer and every approval a game contract asks for is paid in ETH, and approvals granted to a marketplace or game contract remain in force until they are revoked.

Game sessions produce more signing than most holdings do. With Tangem the signature comes from holding the card against the phone for a second, with the ETH for gas sitting in the same wallet as the tokens, and nothing to charge or plug in between sessions. Keeping the play balance and its fee coin under one card takes the friction out of a token that gets touched often.
