What the data says
USDM
USDM is Mountain Protocol's yield-bearing dollar — a regulated, rebasing stablecoin that pays T-bill yield to holders by growing their balance rather than requiring a stake contract. The deployment 0xbbaec992fc2d637151daf40451f160bf85f3c8c1 is the Ethereum mint; our August 24, 2026 snapshot reads $20 million of tracked pool liquidity.
The honest mechanics: rebasing means balance and "value" move together — a wallet holding USDM sees the unit count tick up daily as yield accrues, which is elegant until accounting or a DeFi pool assumes a static balance. Regulated in Bermuda, permissioned to hold — both the feature set and the limitation come from the same compliance posture.
USDTB
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 September 8, 2026 snapshot reads $20 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.

The grade column is the one CMC's compare page cannot print — our grade is computed from the contract itself (mint/freeze authority, liquidity, holder concentration). Changes are measured over the shared window stated on the chart, 2026-09-15T19:06:11→2026-09-17T20:24:07; a token with fewer measured points measures a shorter span inside it.
