Гаманець для SMARDEX WRAPPED USDN

What is SMARDEX WRAPPED USDN (WUSDN)?

wUSDN is USDN with the rebase switched off. USDN, the synthetic dollar in the SmarDex system, distributes its accrual by adjusting balances, so the number of tokens at an address changes on its own. Wrapping turns that into the other arrangement: a wUSDN balance holds still, and what moves is how much USDN each unit stands for. Internally a wUSDN holding is a share of the USDN pool, and unwrapping hands back whatever that share is worth at the moment you do it.

Why anyone bothers is practical. Rebasing balances confuse anything that records a fixed number of tokens, from accounting spreadsheets to contracts that were never written with rebases in mind. A constant balance is easier to reason about, at the price of one extra step: to get plain USDN you unwrap, and both wrapping and unwrapping are contract interactions on Ethereum, not transfers. So a wUSDN amount should never be read as a dollar figure. The dollars are in the redeemable USDN behind it, and the two numbers are not the same.

Supported networks in Tangem (1): Ethereum.

That unwrap step is where a wallet either helps or gets in the way. With Tangem the transaction is prepared in the phone app, you keep ETH alongside the wUSDN for the gas, and the signature happens when the card touches the back of the phone, with the key never copied out of the chip to do it. Wrapping and unwrapping stay a deliberate, physical confirmation rather than something a compromised phone can approve behind your back, which is the sensible way to hold a share token you will eventually redeem.
