USDB supply history
Its peak was $100.0M in September 2026, and supply is 11% below that high.
Is USDB holding its peg?
There is no live market price for USDB. It is not actively traded on any exchange or DEX we can see, which is common for bank-issued and permissioned stablecoins that are only minted and redeemed directly with the issuer.
Where USDB lives: supply by blockchain
Supply is concentrated: Tempo holds 100% of all USDB. Moving it to another chain means bridging, or a mint and redeem through the issuer.
How USDB is backed
Each USDB is meant to be redeemable for one unit of its reference currency, backed by reserves such as bank deposits and short-term government debt held by the issuer or its custodians.
Minting and redemption: USDB is backed 1:1 by U.S. dollar-denominated reserve assets and can be exchanged for fiat or other stablecoins through Bridge's Orchestration APIs.
USDB risks
Your claim is on the issuer and the banks or funds holding its reserves. A failure or freeze there can break the peg, as USDC briefly did in March 2023.
Fiat-backed issuers can usually freeze tokens at specific addresses, for example to comply with sanctions or court orders.
Rules such as the US GENIUS Act and the EU's MiCA can restrict which stablecoins exchanges list in a given country.
