Wrapped Savings rUSD wallet

What is Wrapped Savings rUSD (WSRUSD)?

Three tokens sit in a row in the Reservoir system, and wsrUSD is the last of them. rUSD is the stablecoin, backed by a mix of real-world instruments and on-chain collateral positions. Depositing rUSD into the savings contract produces srUSD, which represents that deposit. wsrUSD then wraps srUSD into a form whose token count is constant, with the srUSD each unit is worth tracked by a conversion rate instead.

The practical reading of that: a wsrUSD balance will look frozen. That is the intended behaviour, and it is also why the wrapped form travels well - a token with a stable quantity is much easier for bridges and contracts on other chains to handle than one that keeps rewriting balances. Unwinding goes back down the chain, wsrUSD to srUSD to rUSD, on the network where the savings contract lives.

Supported networks in Tangem (9): Base, Ethereum, Arbitrum One, BNB Smart Chain, Solana, HyperEVM, Avalanche, Katana, Sei Network. Each is a separate deployment with its own balance, and each charges its own native coin for gas.

Holding it takes no maintenance at all. There is no claim to make and no periodic action on the owner's side; the Tangem app reads the address straight from the chain and shows what is there, whenever you happen to open it. A card that spends most of the year in a drawer loses nothing by doing so with this token, which is a fair reason to park it here.
