SYBTC — syBTC — is a yield-bearing bitcoin token on Ethereum: BTC price exposure wrapped in a structure that accrues yield, with the "sy" prefix the standard marker for yield-bearing wrapper tokens. The contract 0x01a8b61e7b03891a736b5df865e0ef9c511850ad is what our scan tracks: $855 thousand of pool liquidity as of September 8, 2026, priced tracking bitcoin.
The honest ledger for yield-wrapped BTC: your return is BTC price plus whatever strategy the issuer runs underneath — and your risk is that strategy, its counterparties, and the wrapper's smart contracts on top of the price itself. Yield on bitcoin is never free; the question every sy-token holder should be able to answer is where the yield comes from and what happens when that source turns.
Fukabu was one day old when HostDeFi's snapshot caught it on August 19, 2026, and age is the right place to start, because every other number on this page should be read through it. In its first day of existence, FKB's venue feed claimed roughly $2.19 billion of pool liquidity and $2.45 billion of daily volume — depth that would rank it among the largest markets in crypto — alongside a recorded market capitalization of zero and no holder count whatsoever. Genuine markets do not look like this at any age; brand-new ones only look like this when the reporting venue's figures are being inflated, usually by wash trading against self-provided reserves.
What our read did and didn't do here matters. On EVM chains, HostDeFi's snapshot grades market structure from venue data; it does not open the contract. So nothing on this page speaks to whether FKB at 0xe549920f83178586c8536400862f5349c0d2d883 can mint supply, tax transfers, block sells, or be drained by an owner key — the standard failure modes of fresh Base-chain tokens. The B grade reflects only the market inputs the capture carried, and those inputs are precisely what this essay is telling you not to trust.
By tracked market cap: SYBTC (Ethereum) measures — and FKB (Base) measures — — dated snapshots, not a live feed.
On the contract checks we publish: SYBTC (Ethereum) grades B and FKB (Base) grades B. A grade is a structural check on the contract, not a promise about the asset.
Between 2026-09-08 and 2026-09-17T20:24:07, the measured snapshots show SYBTC at 0.00% and FKB at 0.00%.

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, 2026-09-08→2026-09-17T20:24:07; a token with fewer measured points measures a shorter span inside it.
