USDtb

USDtb (USDTB) is a U.S. dollar stablecoin that keeps its peg with cash and cash-equivalent reserves, but distinguishes itself by parking roughly 90% of those reserves in BlackRock's tokenized money-market fund BUIDL — the highest BUIDL allocation of any stablecoin.

How BUIDL-backed reserves let USDtb scale

Holders can transfer USDtb freely without restriction, and using an institutional tokenized fund as the primary backing lets it scale without the practical limits of holding reserves as scattered bank deposits. It runs on Ethereum and Solana, sharing the familiar look of USDC or USDT while leaning on a different, on-chain reserve structure.

Reserve quality versus single-fund dependence

The bull case is reserve quality and transparency: BUIDL is backed by short-term Treasuries and managed by the world's largest asset manager, arguably a cleaner backing than opaque commercial-bank balances. The bear case is dependence on that single fund's redemption and liquidity behavior, the issuer's own track record and associations, and the general regulatory uncertainty over dollar stablecoins. USDtb suits users wanting a fiat-pegged token with institutional-grade collateral, used as trading and settlement cash rather than a yield source.
