WBTC is the original wrapped Bitcoin — the ERC-20 that put BTC on Ethereum's DeFi rails in 2019, custodied by BitGo with a mint-and-burn pipeline run through KYC'd merchants. The deployment 0x2260fac5e5542a773aa44fbcfedf7c193bc2c599 is the canonical mint, one of the oldest contract addresses in DeFi; our October 9, 2026 snapshot reads $220.7 million of tracked pool liquidity on this pair set — a slice of a float that spans every major venue.
The honest frame is unchanged since launch: holding WBTC means trusting BitGo's custody — the reserve is attested and the mint pipeline is transparent, but the claim is institutional, not cryptographic. Coinbase's cbBTC arrived as the regulated-competitor answer; the two trade the same BTC exposure with different custodians, and the depth split between them is the market's live verdict on whose custody it prefers.
AMWBTC — Aave's Polygon-market WBTC receipt at 0x5c2ed810328349100a66b82b78a1791b101c9d61 — is not a token you buy so much as a receipt the Aave pool issued when someone deposited WBTC: it tracks a claim on the deposited bitcoin plus accrued interest, priced at $81,051 per unit on a 62-unit supply at the October 6, 2026 snapshot.
The profile fits a receipt token: an upgradeable proxy by design (Aave upgrades market logic behind the same addresses), verified source, $943 thousand of healthy depth, 9,807 holders, and 1,518 days of operation. The ten largest wallets hold about 53.4% of the tiny unit supply — expected, since the biggest depositors hold the most receipts.
By tracked market cap: WBTC (Ethereum) measures $9.63B and AMWBTC (Polygon) measures $5.14M — dated snapshots, not a live feed.
On the contract checks we publish: WBTC (Ethereum) grades C and AMWBTC (Polygon) grades B. A grade is a structural check on the contract, not a promise about the asset.
Between 2026-09-21 and 2026-10-15T21:43:45, the measured snapshots show WBTC at −2.64% and AMWBTC at +0.26%.
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→2026-10-15T21:43:45; a token with fewer measured points measures a shorter span inside it.
