- Kraken has opened onchain yield vaults for SPYx, QQQx and NVDAx.
- Launch APYs are 2% for SPYx and QQQx and 1.8% for NVDAx, net of fees.
- The xStocks serve as collateral while borrowed stablecoins generate DeFi rewards.
- Investors keep equity-price exposure but take on additional protocol and liquidity risk.
Kraken is giving tokenized equities a new role beyond trading, launching vaults that use SPYx, QQQx and NVDAx as collateral for DeFi strategies while investors retain exposure to the corresponding stock or ETF. The structure adds a separate yield layer to tokenized equity exposure, but also introduces risks that do not exist when simply holding a stock through a broker.
Kraken Adds Yield to Three xStocks
The initial vaults cover tokenized exposure to the SPDR S&P 500 ETF, Invesco QQQ and Nvidia.
During the launch period, Kraken is displaying an estimated 2% APY net of fees for SPYx and QQQx and 1.8% for NVDAx. The rates are not guaranteed. Kraken says they will ultimately vary with conditions in the underlying markets, with the displayed APY based on a trailing seven-day average.
Rewards accrue continuously, are converted back into the same xStock and automatically compound. Users can request a withdrawal at any time, subject to a three-day waiting period.
The vaults also carry a 25% performance fee on earnings, applied at the protocol level. Kraken says the displayed APY is already net of that charge.
Where the Extra Yield Actually Comes From
The 2% return on SPYx is not additional income generated by companies in the S&P 500. Nor does NVDAx suddenly make Nvidia itself pay investors another yield. Because the strategy borrows stablecoins against xStock collateral, it also introduces liquidation risk. If the value of an asset such as NVDAx falls sharply, the collateral position could breach required thresholds and be liquidated to repay the outstanding debt.
The mechanics happen entirely onchain.
When an investor allocates an eligible xStock, Kraken moves it into an embedded non-custodial wallet on the Ink network. The asset is wrapped and deposited into a Veda vault managed by risk manager Sentora.
From there:
- The xStock is supplied as collateral to a lending protocol.
- Stablecoins are borrowed against that collateral.
- Those stablecoins are deployed into DeFi strategies designed to generate rewards.
- The rewards are converted back into the original xStock and automatically reinvested.
Kraken provides access to the vault, but says it does not control the underlying strategy or protocols.
That makes the economic proposition clearer. Investors are not receiving a larger corporate dividend. They are being compensated for putting tokenized equity exposure into a separate DeFi strategy.
A Stock, an xStock and a Vault Are Not the Same Position

What Investors Gain and What They Add in Risk
The trade-off:
moving from a stock to an xStock vault adds onchain utility and potential yield, but each step introduces another layer of risk.
*Shareholder rights depend on the underlying security. Vault APYs are variable and not guaranteed.
xStocks are tokenized representations backed 1:1 by underlying stocks and ETFs, but they do not confer ownership of the underlying security or shareholder voting rights. Dividends from the underlying asset are instead reflected by increasing the holder’s balance of the same token.
Moving an xStock into a vault adds another layer because the position becomes dependent on the infrastructure executing the DeFi strategy.
The 2% APY Comes With a Different Risk Profile
Kraken identifies smart-contract, liquidity, bad-debt and market risks among the potential vulnerabilities of the vaults.
Liquidity is particularly relevant because the three-day withdrawal period does not mean assets are guaranteed to become immediately available under every market condition. Kraken says withdrawals could be delayed during periods of high demand or market stress if sufficient liquidity is unavailable.
The deposits are also not covered by government or bank protection programs, and Kraken explicitly warns that users could lose some or all of their allocation.
That changes how the advertised APY should be interpreted. The relevant comparison is not simply 2% versus zero. Investors are receiving additional potential return in exchange for introducing a DeFi strategy between themselves and their tokenized equity exposure.
Tokenized Stocks Now Need to Prove Their DeFi Utility
Kraken already allows eligible clients to trade more than 100 tokenized stocks and ETFs, with fractional access and onchain withdrawals among their differences from conventional brokerage holdings.
The new vaults test something more ambitious: whether those assets can support financial activity after they have been tokenized.
SPYx, QQQx and NVDAx are useful starting points because they represent familiar, highly traded traditional-market exposures. If the vaults attract sufficient capital and produce sustainable yields, tokenized stocks gain a use case beyond extended trading hours and blockchain transferability.
But the initial rates also provide a benchmark. Once the launch estimates end, borrowing conditions, DeFi returns, fees and liquidity will determine whether the additional yield remains attractive enough to justify the added risk.
Geographic reach will constrain that experiment initially. The vaults are available to eligible EEA and other supported clients but are excluded in the US, UK, Canada, Australia and UAE, alongside sanctioned jurisdictions.
The important number to watch is therefore not how many stocks Kraken tokenizes next. It is what happens to the 1.8% to 2% launch yields once they begin reflecting actual onchain market conditions.
