USDtb is BlackRock's tokenized-T-bill answer to Tether — the stablecoin Ethena issues backed by BUIDL fund shares, built to hold a dollar peg with the largest asset manager's fund as the reserve. The deployment 0xc139190f447e929f090edeb554d95abb8b18ac1c is the Ethereum mint; our October 6, 2026 snapshot reads $11 million of tracked pool liquidity.
The honest framing: USDtb's reserve is only as liquid as BUIDL itself — a fund that settles like a security, not a money-market claim, which means redemptions inherit the fund's terms, not a stablecoin's usual instant-exit promise. That is a feature for holders who want T-bill duration and a constraint for anyone assuming redemption is instant.
Figures are HostDeFi's read dated October 6, 2026; the live scan refreshes them.
Balance concentration: the 10 largest token accounts hold 90.12% of USDTB's supply as of 2026-09-27 — a heavily concentrated distribution — a handful of accounts can move or exit this market at will. Note these are token accounts: liquidity pools, exchange wallets and lockers count among them, so read this together with liquidity, not instead of it.

FAQ
Is USDTB a safe token?
As of the 2026-10-09 snapshot, USDTB scores 80/100 (grade B) on HostDeFi's on-chain read — based on a contract that has unconfirmed mint controls, has unconfirmed freeze and blacklist controls, liquidity of $10.50M and 295,077 holders, with the creator wallet holding <0.01% of supply. That grades contract and market structure, not price direction — a clean read is not a guarantee, so re-scan before trading, since on-chain state can change.
Can you sell USDTB, or is it a honeypot?
Our Ethereum read covers market structure, not sell-side contract behaviour like honeypots or transfer taxes, as of 2026-10-09. Before assuming you can exit freely, run the live scan above — it reads the contract directly.
Who holds most of USDTB?
The wallet that created USDTB holds <0.01% of the supply as of 2026-10-09 — a small stake, under the 5% the scanners flag. That sits alongside a holder base of 295,077; a broad base lowers the odds that any one seller can steer the price, but the creator's share is the number to watch first.
Can USDTB's supply be inflated?
This snapshot grades market structure only — contract-level supply controls on Ethereum aren't assessed here yet. Run the live scanner, which reads the contract in real time.
What is the USDTB contract address?
The USDTB contract address on Ethereum is 0xc139190f447e929f090edeb554d95abb8b18ac1c. Always verify a token by its contract address, not its name or ticker — scam clones copy tickers, but the address is unique.
Where can you buy USDTB safely?
Run the live on-chain scan at the top of this page first; if USDTB clears, you can swap it here directly. Whatever venue you use, match the contract address (0xc139190f447e929f090edeb554d95abb8b18ac1c) exactly before trading — copying the ticker is how clone scams catch buyers, and the address is the one field they can't fake.
