What the data says
USDT
USDT on BSC is Tether's dollar on the chain that still clears a meaningful share of stablecoin volume — issued by Binance's peg mechanism under the BEP-20 standard at 0x55d398326f99059ff775485246999027b3197955, the canonical BSC mint. Our September 27, 2026 snapshot reads $601.6 million of tracked pool liquidity.
The honest chain note: this is a pegged representation — the reserve sits with Tether, and the BSC contract is Binance's wrapped issuance of that claim, not a second Tether mint. That makes its risk profile two-layered: Tether's attestation cadence underneath, plus the bridge-custody layer Binance operates on top. For most users the distinction never matters; for anyone holding size it is the entire question.
OP
OP at 0x4200000000000000000000000000000000000042 is the Optimism Collective's governance token — the canonical OP Mainnet deployment sitting in the chain's own vanity address space, not a bridged copy. The September 26, 2026 snapshot counts 1,370,841 holders around a $299.4 million market cap, $559.2 million fully diluted against a 4.3 billion total supply — the gap between the two figures is the unissued allocation the Collective still holds.
The contract posture is worth quoting exactly. Minting is still active — new supply can be minted, consistent with OP's ongoing distribution schedule. Freeze is revoked, and the code is not a proxy. Depth is the soft spot: $1.1 million of tracked pool liquidity is thin against a nine-figure cap, and $2.8 million of 24-hour volume means ordinary exits clear but size should be measured against the pool, not the headline.

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, 2026-09-21→2026-09-26T18:07:24; a token with fewer measured points measures a shorter span inside it.
