TerraUSD (Wormhole) wallet

What is TerraUSD (Wormhole) (UST)?

This is not UST itself. It is UST that was locked on Terra and reissued through the Wormhole bridge as a wrapped token on another chain, which is why the name carries the bridge in brackets. Each chain that received it has its own wrapped contract, and those contracts are not interchangeable with one another: the copy on Solana and the copy on Ethereum are separate tokens that happen to share a name and an origin.

The origin is the part every holder needs straight. UST was Terra's algorithmic stablecoin, and it lost its dollar peg in 2022 when the mechanism that was supposed to hold it there failed. The chain continued as Terra Classic and the token still exists, but it does not track a dollar and has not for a long time. A wrapped version of it inherits exactly that, and adds bridge dependency on top: whether wrapped UST can be unwrapped at all depends on the bridge route between that chain and Terra Classic still being open.

Supported networks in Tangem (5): Ethereum, BNB Smart Chain, Solana, Avalanche, Polygon POS.

With five separate wrapped copies in play, Tangem lists each chain's balance on its own and states the outgoing network before the card signs. An address string looks identical across EVM chains and no wallet can tell which one a recipient is watching, so reading that line is your job, not the software's. What the wallet gives you is the information in front of you at the moment you decide, which is the useful thing when one asset wears five different coats.
