Threshold USD wallet

What is Threshold USD (THUSD)?

thUSD is a dollar-denominated stablecoin that nobody prints on your behalf: it is borrowed into existence. Someone locks collateral - tBTC, the Threshold Network's Bitcoin representation on Ethereum, or ETH - into a vault and mints thUSD against it, always leaving more collateral behind than the debt is worth. The design follows the Liquity model: over-collateralised vaults, a stability pool that absorbs liquidated positions, and redemptions, meaning thUSD can be exchanged back against the collateral of the least-collateralised vaults. That redemption path is what anchors the token to a dollar rather than any company's promise to honour it.

For someone simply holding thUSD, this is quieter than it sounds. The token is a plain ERC-20 on Ethereum: your balance does not change on its own, the number stays where you left it, and moving it costs ETH like any other Ethereum transfer. Being a borrower and being a holder are separate roles - if you did not open a vault, there is no position to watch and no liquidation that can touch the tokens in your wallet.

Supported networks in Tangem (1): Ethereum.

What matters then is the key that controls a balance you may not touch for months. Tangem generates it inside the card's secure element, where it is created and stays; a second card from the same set reproduces the same wallet if the first one disappears, and writing down a seed phrase is a choice rather than a requirement. Dollars you are holding still deserve storage that does nothing while you ignore it, and this is that.
