Where they differ

What the data says

B3

There's a small gap on this page — B3's contract flags weren't fully confirmed as of 2026-09-14. So rather than assume anything either way, it's worth a direct check, and the scanner above reads it live in a couple of seconds before you trade.

On the market side, B3 brings deep liquidity of $674.20K and an established record at 581 days as of 2026-09-14. Treat $674.20K as the room your trade has to work in — the smaller the pool relative to your size, the more your own order moves the price.

USDT

USDT is the oldest and largest dollar token on the internet — Tether's dollar, the reserve currency of offshore crypto trading since 2014, and the settlement asset most of the industry's volume clears in. The contract at 0xdac17f958d2ee523a2206206994597c13d831ec7 is the canonical Ethereum deployment; our September 16, 2026 snapshot reads $49.8 million of tracked pool liquidity, which is only what our sampler sees — USDT's real depth spans dozens of venues and most of it sits in order books and OTC desks our pool read does not enumerate.

The honest complications are the well-known ones. Tether's attestations are not a full audit, its reserves have historically included things beyond cash, and the contract itself retains freeze and blacklist controls — a stablecoin where the issuer can seize a balance is a different instrument than one that cannot. None of this is new or disqualifying; it is the price of the deepest dollar liquidity in crypto, and the reason the scan above reports what it reports.

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, 2026-09-14→2026-09-17T20:24:07; a token with fewer measured points measures a shorter span inside it.
