"Based on activity rewards" mandatory order: Restructuring DeFi architecture for the US crypto bill

Coinbase’s withdrawal of support for the Senate “Market Structure Bill” appears to be a political game, but in fact it is triggering a chain reaction at the technical level. The provision in the draft regarding “prohibiting earning rewards for simply holding stablecoins” essentially redefines the standards for the legality of on-chain earnings. For global DeFi developers, this potential legal requirement is transforming into a series of urgent technical challenges. The topics discussed by Brian Armstrong at the Davos negotiation table will ultimately manifest as logical judgments that must be implemented in smart contracts. We need to temporarily set aside macro discussions and delve into the code level: how will this bill force a fundamental restructuring of DeFi architecture?

From legal terminology to on-chain logic: deconstructing the technical definition of “activity”

Converting legal provisions into executable code logic is the core of this regulatory challenge. Clear concepts in traditional finance require a new framework of definitions in the distributed environment of blockchain. The requirement for “activity-based rewards” forces developers to design technical solutions that can precisely distinguish between “passive holding” and “active contribution.” This is not just a semantic distinction but relates to the legitimacy of the entire revenue distribution mechanism.

In smart contract design, verifying the authenticity of “activity” becomes a key challenge. Simple balance checks are no longer sufficient; contracts need to identify economically meaningful contribution behaviors. This means protocols must integrate complex validation logic capable of analyzing transaction patterns, assessing the authenticity of liquidity provision, and confirming staking behaviors’ actual contribution to network security. Development teams need to build these verification mechanisms while maintaining the decentralized nature of the protocol, which undoubtedly raises higher requirements for protocol architecture.

Rebuilding the revenue engine: from static staking to dynamic contribution proof

The current DeFi protocols generally adopt a static revenue model that faces reconstruction pressure. The simple balance and time-based calculation models need to evolve into dynamic evaluation systems capable of quantifying multi-dimensional contributions. Future revenue engines may need to maintain a complex contribution graph, tracking users’ various behaviors within the protocol in real-time and evaluating their value.

This architectural shift presents significant technical challenges. Protocols need to design reasonable contribution metrics, establish mechanisms to prevent gaming, and ensure a balance between computational complexity and Gas costs. More importantly, this shift requires developers to rethink the design philosophy of protocol economics, moving from simple token release schedules to more refined incentive mechanisms.

Impact on mainstream protocol models: the evolution pressure on lending, DEX, and aggregators

Lending protocols face the most immediate interpretative challenges. The traditional qualitative assessment of deposit interest may need to be re-evaluated, and protocols might need to adjust their interest rate models to more clearly link rewards to the actual usage scenarios of funds. This could lead to more complex interest rate curve designs, incorporating more market variables.

Decentralized exchanges, although their liquidity provision mechanisms naturally fit the “activity” definition, may require redesigning their additional token incentive plans. Protocols need to consider how to more precisely allocate incentives to liquidity providers who genuinely contribute to trading experience, rather than simply distributing based on deposit proportions.

Yield aggregators face the most complex challenges. They need to optimize yields while ensuring that the activities of funds within each protocol comply with regulatory requirements. This demands the development of smarter strategy engines capable of understanding and adapting to different protocols’ contribution rules and generating corresponding compliance proofs.

Guidelines for builders: coding the future amid uncertainty

In the face of regulatory uncertainty, developers should adopt forward-looking technical strategies. During protocol design, they should consider linking yields to verifiable contributions, avoiding reliance solely on holding reward models. This requires establishing contribution measurement systems early in the design process and considering how to integrate them into the protocol architecture.

Investing in on-chain analytics infrastructure is crucial. Protocols need to accurately track and verify user behaviors, which may require integrating specialized analysis tools or developing custom tracking systems. Additionally, adopting modular design can help protocols more flexibly adapt to future regulatory changes, decoupling yield logic from core business logic and reducing the complexity of system reconstruction.

Actively participating in industry discussions and standard setting is also valuable. Co-developing implementation standards for “activity-based rewards” can help the entire ecosystem adapt to new regulations more orderly and ensure interoperability among different protocols. The developer community needs to collaboratively explore how to maintain DeFi’s openness and innovation spirit while meeting regulatory requirements.

Compliance as a new boundary of innovation

Regulatory requirements are becoming new variables in DeFi protocol design. The discussion triggered by the US Market Structure Bill is essentially a deep dialogue between traditional financial regulatory frameworks and emerging decentralized financial systems. The outcome of this dialogue will directly influence the technological evolution direction of DeFi protocols in the coming years.

For teams capable of transforming compliance requirements into technological advantages, this could become a significant differentiator. Converting regulatory concepts like “activity-based rewards” into fairer, more transparent, and sustainable protocol mechanisms is both a challenge for developers and a potential catalyst for maturing DeFi. Ultimately, the protocols that can withstand the test will be those that find an elegant balance between innovation and compliance.
