## Revenue Distribution Mechanism in the Decentralized Era: How Builders' Codes Reshape App Economies

In the rapidly evolving world of decentralized applications, a new mechanism has emerged that changes how developers earn profits — a unified system linking user activity with direct revenue. This mechanism is not limited to a single platform but is beginning to spread across the entire ecosystem.

### Who benefits from the programmed referral model?

The real implementation of this concept resembles multiplayer gaming platforms — providing the core infrastructure, while external developers build interfaces and applications, sharing revenues based on the actual volume generated.

Applications as engines of growth: trading bots, AI agents, and digital wallet solutions — all of these can generate real activity volume on other platforms without needing to build the infrastructure themselves.

### Case Study: How Wallet Apps Made Millions of Dollars

Since one prominent wallet app added a perpetual contracts trading feature mid-last year, it has been generating revenues of up to one hundred thousand dollars daily from this service alone. The mechanism is simple: the user transfers funds directly from the app, executes trades within the interface, and each transaction is recorded with a unique code attributed to the app, which charges a 0.05% fee.

Tangible results:
- Cumulative trading volume reached $20 billion in six months
- Total revenue hit $10 million
- In just one day, nearly $150,000 was earned

What’s notable is that one of the largest users lost 99% of their wallet (worth approximately $2 million), and paid about $191,000 in fees — reflecting the true scale of activities generated through these channels.

### Ecosystem Expansion of the Mechanism

This experience was not limited to a single platform. Prediction market platform other adopted a similar model this year, launching a weekly USDC rewards program aimed at external developers. Although modest compared to larger platforms, the program:
- Facilitated over $50 million in activity volume through external apps
- Attracted a diverse team to develop unique user interfaces
- Created a public dashboard to track top developers and their yields

### Deeper Level: Ethereum’s Attempt at Standardization

While current mechanisms are limited to individual platforms, a new standard for the Ethereum network proposes integrating this mechanism at the protocol level itself. The proposal is based on a fundamental idea: adding small data fields to the end of each transaction to identify the original developer, with a smart contract linking this identity to a wallet address for receiving profits.

Main components:
1. **Extended Data Field**: Allows developers to attach an identifier code at the end of their transactions
2. **Decentralized Distribution Registry**: A smart contract that maintains the link between codes and wallets

This approach transforms builders’ codes from a platform-specific feature into a unified mechanism that any platform or protocol can implement.

### Overall Statistics of the Model’s Success

On platforms that have implemented this system so far:
- Distributed revenues to developers exceeded $40 million
- Over $100 billion in additional activity volume was generated
- The quality of built applications improved significantly due to direct incentives

### Future Outlook

A unified system across Ethereum could open the door to a new wave of high-quality consumer applications. Instead of relying on external funding, developers receive continuous, predictable revenue based on the actual value they create for users. This shifts the model from a support system to a sustainable one — good developers continue, while weaker applications naturally fade away.
