What is Apyx?

Apyx is a Dividend-Backed Stablecoin (DBS) protocol operated by Preference Capital that turns dividends from publicly-traded preferred equity into onchain yield. It runs a dual-token model: apxUSD, a non-yield synthetic dollar built for deep secondary-market liquidity and collateral use across DeFi, and apyUSD, a yield-bearing savings asset that accrues dividends paid by Digital Asset Treasury (DAT) companies such as Strategy (MSTR).

‍

The Challenge

Apyx had spent months building a dual-token model, securing partnerships, and preparing for a mainnet launch. The product was ready. Now the team faced the harder question: how do they drive real adoption of apxUSD and apyUSD and turn that adoption into sustainable protocol revenue? They entered a discovery phase, evaluating which growth mechanic would actually bring users in and scale the ecosystem.

They needed to:

• Track user activity across a growing list of DeFi venues: every new partnership (vaults, lending markets, LP pools, yield tokenization) meant a new surface where users held apxUSD or apyUSD positions.
  
  
• Turn existing users into an acquisition channel: the team wanted users to drive organic growth, but any standard referral model risked being gamed by self-refer loops and Sybil farming.
  

‍

The Solution

Rather than allocating months of engineering to build a multi-protocol attribution system (tracking net positions across lending markets, Curve pools, and Pendle yield tokens with protocol-specific logic per integration), commitment tracking with unlock windows, cross-chain infrastructure to follow users across networks, and a Sybil-resistant referral engine with dynamic 1:1 caps, Apyx chose Fuul as the layer that handled attribution and distribution across every surface. This let the team launch their product with the Pips program live from day one, while staying focused on supply growth and new chain expansion.

With Fuul, Apyx:

•  Ran net position tracking across multiple DeFi venues: with protocol-specific attribution logic, covering direct holdings, committed balances, LP positions, and yield-tokenized positions.
  
  
•  Expanded from Ethereum to Base in minutes: after launching on Ethereum, adding Base to the Pips program was a configuration change on Fuul, not an engineering project, so Apyx could follow user demand to a new chain without rebuilding anything.
  ‍
• Ran referrals with a dynamic 1:1 cap against the referrer's own organic earnings: every point earned from referred activity has to be matched by a point the referrer earns as an end-user, so referring alone is never enough to extract value from the program. This forces referrers to stay active themselves, neutralizes self-refer loops and farming, and keeps legitimate referrers uncapped as long as they keep participating.
  
  ‍

"Fuul let us reward user activity across Pendle, Curve, Morpho, and our own vaults from day one, without writing custom code on our side. We launched the Apyx Pips points program with all integrations live at launch and were able to keep our team focused on the core product."

Results

After ~8 weeks since the Ethereum launch on February 27, 2026:

• Apyx ecosystem grew to ~2,300 unique users.
  
  
• Referrals became a core acquisition channel, bringing ~1,300 users (~57% of the ecosystem).
  
  
• apxUSD locked in the apyUSD vault surpassed $69M
  
  
• apxUSD total supply scaled to ~$190M

Conclusion

By routing the Pips program through Fuul, Apyx rewarded genuine DeFi activity across a complex multi-protocol stack without building custom indexing or referral infrastructure. The referral system brought in ~57% of new users organically, driven by a dynamic 1:1 cap that kept the channel fair and Sybil-resistant.

Apyx's program shows a best practice for any team running referrals: don't let referrers just refer. By tying their earnings 1:1 to their own organic activity, Apyx turned every referrer into an active user of the protocol, creating a growth loop where referring and participating reinforce each other.

Today, Fuul provides the tracking and referral infrastructure Apyx needs to grow apxUSD adoption across Ethereum and Base, without pulling the core team away from the product.
