Where they differ

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.

RYY

The most useful thing this page can tell you about Reyayu is that its numbers do not add up, and that you should treat that as the finding rather than a gap in it. When HostDeFi captured RYY on August 19, 2026, the token was roughly one day old — and the venue data attached to it claimed about $2.26 billion in pool liquidity and $3.48 billion in daily volume, while reporting no market capitalization and no holder count at all. A day-old token with more claimed depth than most top-fifty assets, and nothing else on the books, is not a growth story. It is the signature of inflated venue-reported figures: self-dealt volume and reserve numbers a listing API repeats without judging.

Be equally clear about what this page has not checked. Our Base-chain read covers market structure only — it has not assessed this contract's mint controls, owner privileges, transfer taxes, or sell-side behavior, which is exactly where fresh EVM tokens hide their traps. The B grade shown here scores the market-shape inputs the snapshot carried; it is not a contract audit, and on a token like this the contract is the entire question.

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, 2026-08-24→2026-09-17T20:24:07; a token with fewer measured points measures a shorter span inside it.
