USDtb wallet

What is USDtb (USDTB)?

USDtb is a fiat-backed dollar stablecoin created by Ethena, the same team behind the synthetic dollar USDe, and now issued by Anchorage Digital Bank. Where USDe keeps its peg with hedged crypto positions, USDtb takes the conventional route: each token is backed by cash and cash equivalents, and most of that reserve sits in BlackRock's tokenized money market fund BUIDL. That makes USDtb the plain, reserve-backed dollar in Ethena's lineup, and Ethena itself uses it as one of the backing assets behind USDe when market conditions call for it.

For a holder the mechanics are simple. USDtb does not rebase and its balance does not change on its own: one USDtb stays one USDtb until you send it. The token itself does not pass on anything the reserves generate, so there is nothing to claim or manage. Minting and redeeming against the reserves is reserved for the issuer's onboarded clients; everyone else buys and sells it on the open market and holds it like any other stablecoin.

On Ethereum it is a standard ERC-20, so every transfer costs gas in ETH. On Solana it is an SPL token: the first deposit to a fresh wallet creates a token account, and each transfer costs a small amount of SOL. Keep a little of the native coin next to your USDtb on each chain or the balance will sit there untouchable.

One thing to watch is the name. USDtb is not USDT, and a wallet that lists both side by side can make them look interchangeable. They come from different issuers with different reserves, and sending one where the other is expected is an unrecoverable mistake.

Supported networks in Tangem (2): Ethereum, Solana. The app keeps a separate USDtb balance for each of them and tells you which network an outgoing transfer uses before the card signs, so the check between chain, token and recipient happens on your side, on screen, every time. With an asset that spans two very different networks and shares a near-identical ticker with a far larger coin, that clarity at the moment of signing is the reason USDtb belongs in Tangem.
