USX wallet

What is USX (USX)?

Scroll, the Ethereum zk-rollup, issues USX as its own dollar token: a unit meant to hold at one US dollar, with collateral held against every USX in circulation. It is not a wrapped or bridged copy of some other stablecoin. It is minted natively on Scroll, and Scroll is where it lives and where it is meant to be spent.

A few things matter once it sits in your wallet:

• Fees on Scroll are paid in ETH, not in USX. A wallet holding only USX cannot move it, so keep a little ETH on Scroll alongside. The gasless spending USX is designed for runs through chain-level customizations and payment partners, not through an ordinary transfer from a self-custody address.
• The ticker is shared. An older, unrelated stablecoin issued by a DeFi lending protocol also trades as USX on Ethereum and several other networks. Same three letters, different issuer, different contract. The network is what tells them apart: Scroll's USX exists on Scroll.
• Privacy is a separate layer, not the default. USX at a normal Scroll address is as visible as any other ERC-20 balance; shielding it goes through Cloak, Scroll's privacy layer, as its own step.

Supported networks in Tangem (1): Scroll.

Since the two USX tokens differ only by where they live, the Tangem app files each balance under its own network instead of one shared ticker line, and before the card signs an outgoing transfer the app shows which network it leaves on. Reading that line is still on you; the app supplies the fact, not the decision. For a dollar whose identity is its chain, that is exactly the detail worth having in front of you every time.
