Гаманець для Savings USDD

What is Savings USDD (SUSDD)?

sUSDD is a wrapper, not a second stablecoin. USDD goes into a savings contract, sUSDD comes out as the receipt for that deposit, and the contract's internal ratio between the two is what moves over time; redeeming gives back USDD according to that ratio. The number of sUSDD tokens in a wallet does not change by itself, which is exactly why the figure on screen can look frozen while the underlying claim is not.

That makes one habit important: judge the position in USDD terms after redemption, not by counting sUSDD units. And treat sUSDD as a distinct token in transfers. It is not interchangeable with USDD, an address expecting one will not credit the other, and anything quoting a price for USDD is not quoting this token.

The wrapper exists on more than one chain, and the deployments are separate contracts rather than one balance visible from several places. Moving between them is a bridging operation, not a transfer.

Holding it

Tangem keeps each chain's balance on its own line, and the outgoing network is named on the confirmation screen before the card is tapped, so it is on you to check that it matches what the recipient expects. The address alone will not tell you, on EVM chains it is identical everywhere. For a token that exists in more than one place under one ticker, having the chain spelled out at signing time is the part worth having.
