Гаманець для Wrapped USDM

What is Wrapped USDM (WUSDM)?

WUSDM is the non-rebasing form of USDM, the dollar token issued by Mountain Protocol. USDM itself is built to rebase: the balance in an address is adjusted upward on a schedule, so the number of tokens changes while each one stays a dollar unit. That behaviour breaks a lot of contracts, and it also means the token count in a wallet moves without anyone signing a transaction.

WUSDM turns that around using the ERC-4626 vault standard. Wrap USDM and the wUSDM balance is fixed from then on; what moves instead is how much USDM each wUSDM converts back to. This is why wUSDM is never worth exactly one dollar and should not be read as if it were - it is a share of a vault holding USDM, and the conversion ratio is the number that matters.

A holder should know two things beyond that. Unwrapping returns USDM, which resumes changing its own balance immediately. And the token is deployed widely: Supported networks in Tangem (7): Ethereum, Optimism, zkSync, Base, Arbitrum One, Avalanche, Polygon POS. The ticker is identical everywhere, the contracts are not, and moving between them takes a bridge rather than a transfer.

With that many deployments, Tangem holding each one as its own separate balance, and naming the network on the screen where you confirm, is what keeps the picture honest - you see where the tokens actually sit rather than one merged number, and you read the destination chain before the card signs. That separation is the sensible way to keep an asset that exists in seven places at once.
