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 27, 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.
SUSDAI is the staked wrapper of USDai — the yield-bearing form of a dollar token issued against AI-infrastructure financing — trading on Arbitrum at 0x0b2b2b2076d95dda7817e785989fe353fe955ef9. The September 26, 2026 snapshot reads $10.1 million of tracked pool liquidity, the deepest single line item in this slice of the index.
What the numbers say: roughly seven months of trading history behind it, about $2.2 million of 24-hour volume against that liquidity base — a turnover ratio near 12%, the shape of a yield instrument held rather than churned. The ~$1.11 print against a $1-asset wrapper is consistent with accrued staking yield rather than a broken peg, though the snapshot alone cannot separate the two.
By tracked market cap: USDTB (Ethereum) measures $490.66M and SUSDAI (Arbitrum) measures $496.25M — dated snapshots, not a live feed.

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, 2026-09-18T04:43:53→2026-09-27T18:22:06; a token with fewer measured points measures a shorter span inside it.
