Covered calls can limit upside. Yield is not guaranteed.

The gap in passive equity ownership

The problem

A tokenized equity position
is not a plan.

0103

Ownership is not
a strategy.

Tokenized equities make an asset portable and easy to hold on-chain. But a balance by itself does not define what to do with the position, how to generate value, or what happens when the market moves.

The market moves.
Your position doesn’t.

An exposed equity position can track the market, but it can remain undefined while the market changes. Price movement alone is not a productive plan.

On-chain ownership
still needs an outcome.

Blockchain settlement makes the position verifiable. It does not automatically explain which outcome applies, when it applies, or how the holder should claim it.

The opportunity

Equity exposure.
With a pulse.

Tokenized stocks keep the familiarity of equity with the settlement properties of a blockchain. Harvest adds a productive layer: an automated covered-call cycle that turns idle holdings into recurring USDC premium payouts.

The cycle

01 03

01

Deposit

Deposit xStocks into a Token-2022 vault during its deposit window. Your position is recorded in an on-chain PDA.

02

Lock the cycle

The keeper captures the Pyth Hermes spot price, sets an out-of-the-money strike, and locks the weekly USDC premium.

03

Settle & claim

At expiry, the keeper settles the outcome. Claim your underlying principal (OTM) or USDC proceeds (ITM) plus premium.

At expiry

Two paths.
One clear outcome.

OTM settlement

Keep the underlying.

When the settlement price stays below the strike at Friday expiry, claim your xStock principal and the USDC premium.

100%underlying returned
ITM settlement

Receive USDC proceeds.

When the price exceeds the strike, the keeper converts the underlying through Jupiter and distributes the strike-price USDC proceeds plus premium.
