Wrapped HBAR (SaucerSwap) wallet

What is Wrapped HBAR (SaucerSwap) (WHBAR)?

Hedera keeps native HBAR and the Hedera Token Service on different tracks. HBAR is the coin of the network and pays every fee on it, but it is not an HTS token, so contracts written against the token service cannot take it as input. WHBAR is HBAR in HTS form, created one for one by a wrapper contract, and it is what exchange and pool contracts on Hedera actually handle.

Two Hedera-specific habits shape how this token behaves in a wallet.

Association. Before an account can receive any HTS token it must first be associated with that token; an incoming transfer to an unassociated account simply fails. Association is a paid transaction on Hedera, so the account needs HBAR before WHBAR can ever land in it.

Fees. Hedera's fees are set in fixed dollar terms and settled in HBAR, so the cost of a transfer does not swing with network congestion the way gas auctions do elsewhere.

There is also a versioning point: more than one WHBAR contract has been deployed over time as the wrapper was updated, so confirm which one a pool or interface means before you send.

Supported networks in Tangem (1): Hedera Hashgraph. Since the key stays inside the card and is never re-derived elsewhere, your Hedera account ID and its associations stay exactly as they are through a contract update, with nothing to re-register. For a token that has already changed contract once, that continuity is the practical reason to keep it in Tangem.
