Where they differ

What the data says

WBTC

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.

ALUSD

ALUSD at 0xcb8fa9a76b8e203d8c3797bf438d8fb81ea3326a is Alchemix's USD on Optimism — the dollar that backs the protocol's self-repaying loan structure, where deposited collateral's yield amortizes the borrow. The October 6, 2026 snapshot prices a $10.0 million asset-wide market cap against a $1.6 million fully-diluted read of the local float of 1.7 million units — a small Optimism slice of a multi-chain stable.

The local book is deeper than it looks and quieter than it should be: $1.1 million of tracked depth reads deep against that float, while $1.9 thousand of 24-hour volume is a nearly dormant tape — the pool exists; the flow mostly does not. For an exit-sized holder that pairing is the real information: depth on paper, and a tape that rarely tests it.

FAQ

Which is bigger, WBTC or ALUSD?

By tracked market cap: WBTC (Ethereum) measures $9.63B and ALUSD (Optimism) measures $9.99M — dated snapshots, not a live feed.

Which is safer, WBTC or ALUSD?

On the contract checks we publish: WBTC (Ethereum) grades C and ALUSD (Optimism) grades B. A grade is a structural check on the contract, not a promise about the asset.

How have WBTC and ALUSD performed over the shared window?

Between 2026-09-21 and 2026-10-15T21:43:45, the measured snapshots show WBTC at −2.64% and ALUSD at −0.74%.

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.
