What changed

In the previous public observation on 2026-09-11, Zyfai had been identified as an automated allocation layer advertising up to 35% APY, but tokenized-stock-specific TVL or flow and the duration of the additional USDC reward could not be independently verified. Zyfai has now disclosed a concrete adoption metric of more than $225K deposited in tokenized stocks over one week, stock-specific headline yields of 38.02% for NVDAc and 20.47% for AAPLc, GOOGLc and METAc, and says the USDC incentive has roughly one week remaining. The $225K figure is a one-week deposit amount and should not be treated as current TVL.

Why it matters

The update indicates that capital is beginning to use a higher-level allocation layer that routes Base tokenized stocks into underlying yield venues rather than only depositing directly into individual vaults. The headline yield is not a durable equity yield: it combines returns and incentives at the underlying venues with Zyfai USDC incentives and rZFI rewards. Portals' Week 3 snapshot dated 2026-09-19 showed the underlying NVDA SuperVault at 17.18% APY and roughly $405K TVL, while Zyfai's NVDAc headline is 38.02%, a gap of about 20.84 percentage points. The observations are not directly comparable because timestamps and product scope differ and Zyfai includes additional incentive layers.

Evidence

  • Zyfai public social feed (public mirror) — Zyfai says more than $225K of tokenized stocks were deposited in one week, with up to 38.02% APY on NVDAc and 20.47% on AAPLc, GOOGLc and METAc including incentives, and that USDC incentives for tokenized-stock depositors remain live for roughly one more week. A separate recent post lists NVDAc at 38.06% and AAPLc, METAc and GOOGLc at 20.47%, and attributes yield to underlying yield, protocol incentives, Zyfai USDC incentives and rZFI rewards. 2026-09-21T00:41:08+09:00
  • SIGNA ET STRUCTURA previous Zyfai observation — The 2026-09-11 public observation recorded Zyfai at 9-24% underlying pool yield, an additional 10% APY in USDC and 1.68% APY in rZFI, for a headline maximum of 35% APY, while tokenized-stock-specific TVL and the USDC incentive budget, duration and cap could not be independently verified. 2026-09-21T00:41:08+09:00
  • Portals DeFi TVL September 2026 Week 3 — Portals' weekly snapshot lists the Base NVDA SuperVault at 17.18% APY and roughly $405.19K TVL. The gap versus Zyfai's 38.02% NVDAc headline is about 20.84 percentage points, but Zyfai includes additional USDC/rZFI incentives and the observations differ in time and product scope. 2026-09-21T00:41:08+09:00

Limitations

The more-than-$225K figure is a one-week deposit amount reported by Zyfai and was not independently verified as current stock-specific TVL. The total USDC incentive budget, wallet cap, exact end timestamp, and realized value and vesting terms of rZFI could not be independently verified from the public surfaces retrieved in this observation. Zyfai's 38.02% headline and Portals' 17.18% snapshot differ in timestamp, product scope and reward composition, so they are not like-for-like APY readings. Displayed yield may compress sharply when incentives expire. Additional risks and limitations include the Zyfai smart-account, agent and routing layer, underlying Superform/IPOR and other protocol contracts, tokenized-stock issuer, custody, redemption and eligibility constraints, and the timing mismatch between 24/5 equity markets and 24/7 Base markets.
