tBTC is Threshold Network's trust-minimized wrapped Bitcoin — the decentralized-custody answer to WBTC, where a rotating set of node operators secures the BTC rather than a single custodian. The deployment 0x18084fba666a33d37592fa2633fd49a74dd93a88 is the v2 mint; our September 27, 2026 snapshot reads $26.6 million of tracked pool liquidity.
The honest contrast is the whole point of the asset: tBTC trades BitGo's institutional custody for a threshold-signature committee — no single company can lose or freeze the coins, but the security model is cryptographic-economic (operator collateral) rather than legal, which is a different risk shape, not a strictly smaller one. Its depth vs WBTC's billions is the market's honest verdict on how much that trade matters to people.
uniBTC at 0x93919784c523f39cacaa98ee0a9d96c3f32b593e is a bitcoin-denominated receipt on Optimism, 802 days into its record at the September 27, 2026 snapshot. The asset-wide $249.1 million market cap dwarfs a $331.2 thousand fully-diluted figure priced on 4 local units — four coins' worth on this chain.
The local book is thin against the headline: $226.3 thousand of tracked depth on $10.6 thousand of 24-hour volume — a sliver that mostly sits. Contract-level controls were not assessed in this snapshot.
By tracked market cap: TBTC (Ethereum) measures $348.57M and UNIBTC (Optimism) measures $249.10M — 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, 2026-09-21→2026-09-27T15:10:18; a token with fewer measured points measures a shorter span inside it.
