At the end of April at the Bitcoin 2026 conference, Michael Saylor gave a 47-minute speech.

In that speech, he did not shout "buy Bitcoin" as usual, but instead drew a diagram. The diagram has three layers:

• The first layer, digital capital: Bitcoin itself.
• The second layer, digital credit: The preferred stock STRC issued by Strategy.
• The third layer, digital currency: On-chain stablecoins and yield products built on STRC.

He mentioned three names as representatives of the third layer: Apyx, Saturn, Hermetica.

This is the first time Saylor has publicly included the name of a DeFi protocol in his official blueprint for a "Bitcoin financial empire." In just 9 months, the asset management scale of STRC has reached 8.5 billion dollars, with daily liquidity close to 400 million, making it the largest and most active preferred stock in the world. Saylor stated that the downstream on-chain tokenized ecosystem built on STRC has surged from zero to a scale of 200 million dollars, and he expects it to reach 1 billion within 4 to 8 weeks.

Among the three mentioned projects, Apyx is the largest and fastest one, with the circulating market value of apxUSD and apyUSD exceeding 440 million dollars; Apyx alone holds approximately 130 million dollars worth of STRC, making it the largest on-chain buyer in this ecosystem.

If you only regard Apyx as "another new DeFi protocol," you completely miss its true position.

It is Saylor's BTC printing machine, the first time it has extended into the DeFi pipeline.

Why Saylor's perpetual motion machine needs the DeFi pipeline

To understand Apyx, one has to first understand Saylor's smartest operation over the past year: STRC.

The business model of Strategy essentially revolves around "using money raised from the capital market to buy Bitcoin." The question is, how to continuously raise money without diluting existing MSTR shareholders?

Saylor provided the answer in July 2025 by issuing a type of perpetual preferred stock called STRC.

Simply explained:

• Face value of 100 dollars per share, it never expires, with cash dividends paid monthly, at an annualized rate of about 11.5%.
• If the price is above 100, Strategy will issue new shares and use the money to buy Bitcoin.
• If the price is below 100, Strategy will raise the dividend rate to attract buyers back and pull the price back close to 100.

This is a delicate "self-repairing" machine. Every month, traditional large buyers such as BlackRock and VanEck will buy in bulk (STRC is the third-largest holding in their credit funds), enabling Strategy to obtain cash to continue buying BTC. Just in the first half of 2026, the Bitcoin bought through STRC financing reached about 77,000, which is ten times the net buying volume of all US Bitcoin spot ETFs during the same period.

However, Saylor has a hidden worry: this machine currently only connects to Wall Street and has not accessed the native cryptocurrency capital pools.

The crypto world holds the largest liquidity of stablecoins globally, the deepest DeFi yield networks, with a 350 billion dollar stablecoin market right there. STRC, as an "off-chain Nasdaq security," theoretically exists in a different world from this capital pool.

Apyx's job is to connect these two worlds.

What Apyx is: a transformer

Saylor built a power plant (Bitcoin) and set up a high-voltage transmission line (STRC, generating an 11.5% dividend stream), but this line connects only to industrial major clients (Wall Street funds). Ordinary DeFi users have sockets at 220V and cannot connect to the high-voltage line.

Apyx acts as a transformer. It converts STRC's high-voltage dividend returns into a form that DeFi users can connect directly.

It employs a two-layer token design that is quite straightforward to understand:

First layer: apxUSD, in the shape of a stablecoin, essentially a "delivery voucher" for Saylor's dividends.

You deposit USDC, and Apyx uses this money off-chain to buy STRC stocks (as well as SATA preferred shares of Strive Company, with a dividend of 12.7%). The stocks are kept in a compliant custodial account, and on-chain you receive an equivalent amount of apxUSD. apxUSD itself does not earn interest, its price is anchored around 1 dollar, and it can circulate in places like Curve, Pendle, PancakeSwap, etc.

It looks like an ordinary stablecoin, but its "soul" is a dividend check issued by Saylor.

Second layer: apyUSD, lock apxUSD to start receiving wages.

You lock apxUSD into the protocol and exchange it for apyUSD. From this moment on, all cash dividends paid monthly from STRC and SATA are funneled into the apyUSD pool.

The critical mechanism design is here: not everyone holding apxUSD will exchange it for apyUSD. Those who only act as LP on Curve or earn points on Pendle do not need to exchange. The result is that the originally average 11.5% dividend is spread among a smaller pool of apyUSD holders, which increases what each person can receive, targeting an annualized return of over 13%.

In simple terms: apyUSD is a thickened dividend that a group of "willing to take interest slowly" people receives from a group of "people who only want to use stablecoins."

The entire yield chain is clean: your 13% annualized return comes not from token issuance, not from the funding rates of perpetual contracts, nor from any Ponzi scheme. It comes from a publicly traded company, issuing real cash dividend checks every month.

This is the first time in DeFi history, that the yield of on-chain stablecoins originates from the shareholder dividends of a public market company. Ethena's earnings depend on counterparty liquidity in the contract market, Ondo's earnings rely on US Treasuries, while Apyx's earnings depend on Saylor leveraging Bitcoin to drive the capital flywheel, representing a fundamentally different entity.

Its risks are more "metaphysical" than you think

Having discussed the positive aspects, I must also clarify the other side; the risks of Apyx lie in the narrative layer.

The technical risks are actually the easiest to handle.

Smart contract hacks? The STRC stocks are held in an off-chain custodial account, beyond the reach of a hacker's code. At most, it could steal the LP liquidity on Curve or Pendle, causing minor damage. What if the custodian goes bankrupt? Apyx chose Wolf & Company, regulated by PCAOB, for monthly audits. These are standard issues that any RWA protocol has to face, which can be mitigated through regulation and compliance.

The real risk is a "faith question."

When you buy apyUSD to get a 13% annualized return, you are essentially betting on these two things:

First, you are betting that Saylor's flywheel can keep turning even when BTC crashes.

The dividends from STRC are not a legal obligation; they are a "promise based on economic capacity" from Strategy. Strategy explicitly reserves the right to "reduce, suspend, or delay dividends."

The logic chain for this flywheel is: BTC rises → MSTR rises → strong market confidence → STRC trades above 100 dollars → Strategy can issue new STRC → obtain cash to continue buying BTC.

But what if the opposite happens? If BTC is halved, market confidence collapses, and STRC falls below 100 dollars, then Strategy cannot issue new shares, cannot raise cash to continue buying BTC, and the narrative for BTC weakens again, which creates a reverse symmetrical dynamic. STRC had previously dropped to 90.52 dollars in November 2025.

A 13% annualized return sounds attractive, but its essence is a bullish option on the long-term appreciation of Bitcoin. If nothing happens to BTC, you get your money. If something serious happens to BTC, what you lose is not just a little interest.

Second, you are betting that people are still willing to hold apxUSD without incentive points.

This is a sharper issue. The apxUSD itself does not earn interest, and currently, almost all demand comes from Apyx’s incentive activities (farming for the soon-to-be-released APYX token), with the first season's incentive campaign set to end on May 22.

What happens after the token release? If the price of APYX is below expectations, and an interest-less stablecoin cannot find a real use case in DeFi beyond "incentive speculation", the circulation of apxUSD could drop from 330 million dollars back to 50 million, which is entirely possible. The protocol won't die, but the ecosystem may cool down rapidly.

Additionally, there's a mechanism pit for apyUSD: a 20-day redemption cooldown period. Once you want to withdraw, you have to queue for 20 days and cannot earn interest during that time. If the market experiences turbulence when everyone wants to flee, this redemption channel may get blocked.

What does it ultimately mean?

Setting aside the microscopic tokens, points, and annualized figures, from a higher perspective, Apyx conveys three signals.

The first signal is about RWA. The RWA narrative has been discussed for three years, but the projects that have really emerged are either boring tokenization of US Treasuries (Ondo, Ondo, or Ondo) or illiquid private credit. Apyx is the first to bring "the chicken that lays eggs," a high-yield security that continuously generates dividend cash flow, onto the chain and integrate it into DeFi Lego. It proves that the true alpha of RWA does not lie in "asset transportation," but in "cash flow transportation."

The second signal is about Saylor. He is no longer satisfied with being "the largest Bitcoin whale." What he aims to build is a complete financial stack with Bitcoin as the underlying asset, from capital (BTC) to credit (STRC) to currency (on-chain stablecoins). Apyx has been inserted into this stack by him personally. Regardless of the eventual success or failure, he is already redefining the boundaries of what a "Bitcoin company" means.

The third signal is about DeFi. In recent years, DeFi's yields have increasingly resembled playing "pass the parcel," paying interest to old users through the release of new tokens. Apyx demonstrates another possibility: DeFi can be more than just a self-circulating casino; it can become a downstream distribution network for traditional financial cash flows. If this path can work, it would reset the valuation logic for the entire industry.

Returning to the initial question: should you participate in Apyx?

If you are a conservative miner, locking PT-apyUSD for an 18% fixed annual return is the safest play.

If you want to speculate on the points for airdrops, a 20x leveraged commit lock-up offers the best cost-effectiveness, but don't get carried away.

If you are an observer, then remember the true significance of this matter: This is the first time TradFi and DeFi have seriously shaken hands in terms of cash flow.

Saylor's BTC empire has opened a door for DeFi for the first time. As to whether this door will ultimately become a passage or a crack, we can only wait and see.
