As the Ethereum L2 ecosystem enters the 'multi-scenario coexistence' phase, 'resource idleness and value waste' have become key bottlenecks restricting ecological efficiency. Currently, about 50% of the value created in the L2 ecosystem is idled due to 'lack of reuse ability'—the technical tools developed by developers serve only a single project, users' cross-scenario credit data cannot interconnect, and scenario assets (such as RWA certificates and NFT copyrights) are difficult to reuse. According to the 2024 (Ethereum L2 Ecosystem Resource Efficiency Report), the average reuse rate of L2 technical tools is only 18%, the user cross-scenario value migration rate is less than 25%, and the secondary utilization rate of scenario assets is below 15%. This 'one-time creation, single-use' model leads the ecosystem into a cycle of 'repeated development and value internal friction'. Caldera ($ERA) activates idle value by building a 'cross-scenario value reuse hub' from three dimensions: technology, users, and assets, providing a new path for 'cost reduction and efficiency enhancement' for the L2 ecosystem.

I. The Three Major Idle Issues of Value Reuse in the L2 Ecosystem: The Fragmentation of Technology, Users, and Assets.

1. Difficulty in Reusing Technical Tools: Repeated development leads to high costs.

Technical resources in the L2 ecosystem (such as cross-scenario compliance tools, data collaboration plugins, contract security modules) generally face the issue of 'one-time development and single-use'. On one hand, insufficient tool standardization—differences in the technical architecture of different L2 projects mean that compliance adaptation tools developed by developers for a specific project cannot be connected to other scenarios due to non-unified interfaces. According to industry research, 65% of L2 technical developers need to repeatedly develop similar tools for different projects, increasing development costs by 3-5 times; on the other hand, the lack of reuse revenue— even if tools have cross-scenario adaptation potential, developers lack the motivation to open reuse due to the absence of a 'tool reuse sharing mechanism' in the current L2 ecosystem, where developers can only receive one-time development compensation without earning from subsequent use of the tools. For example, a developer's 'liquidation risk warning tool' developed for a DeFi project could have been adapted for RWA scenario asset risk monitoring but ultimately was only used in a single project due to the lack of reuse revenue, leading to insufficient release of technical value.

2. Low User Value Reuse: Disconnection of Cross-Scenario Credit and Identity.

The 'value accumulation' of users in the L2 ecosystem (such as DeFi credit scores, NFT collection levels, RWA asset holding records) cannot be reused across scenarios, leading to users needing to reinvest costs to establish trust. Firstly, credit data is isolated—users who accumulate 'high collateral credit' in the DeFi scenario need to resubmit asset proof to participate in RWA asset verification. Statistics show that the average cost (time + funds) for users to establish trust across scenarios is 2.8 times that of a single scenario; secondly, identity rights are not interoperable—users who gain 'advanced player identities' in the GameFi scenario cannot enjoy rights such as minting fee discounts in the NFT scenario, resulting in low willingness for users to participate across scenarios. In 2024, the average number of cross-scenario participations for L2 users is only 1.2, far below the 5+ scenario quantity that the ecosystem can provide. This 'fragmentation of user value' not only increases user costs but also prevents the ecosystem from forming a unified user value system, leading to insufficient stickiness.

3. Low Reuse of Scenario Assets: Compliance barriers limit secondary circulation.

In L2 scenarios, core assets (such as RWA real asset certificates, NFT copyrights, medical data usage rights) face difficulties in secondary value mining due to 'compliance adaptation challenges' and 'lack of circulation mechanisms'. On one hand, compliance restricts the scope of circulation—RWA asset certificates must comply with local regulations (such as EU MiCA, US SEC rules) and can only be used in specific scenarios within a single region, making it impossible to re-stake or trade across regions. For example, a certain agricultural RWA project's 'farmland revenue certificate' can only be used in the EU DeFi scenario due to compliance restrictions, preventing entry into the Asia-Pacific market for secondary financing; on the other hand, asset value is difficult to split—'non-standardized assets' such as NFT copyrights and medical data usage rights lack splitting mechanisms, preventing secondary allocation based on demand (e.g., splitting NFT copyrights into 'commercial rights' and 'display rights' for reuse), resulting in asset value being realized only through one-time transactions, and hidden value being buried.

II. Caldera's Value Reuse Activation Plan: The Underlying Logic of the Cross-Scenario Reuse Hub.

Caldera is not simply building a 'resource sharing platform', but is instead constructing a collaborative hub of 'technical tool pool + user value mapping system + asset reuse channel' to solve the reuse dilemma from both mechanism and technology perspectives, converting idle value into ecological increment.

1. Technical Tool Pool: Standardized interfaces + reuse sharing, reducing development costs.

Caldera's 'technical tool pool' aims to solve the problems of 'difficulty in tool reuse and lack of revenue assurance' by activating technical resources through 'standardization + sharing mechanism':

• Interface Standardization Adaptation: The central system defines unified technical interfaces and data formats for L2 core technical tools (compliance adaptation, data collaboration, contract security, etc.), allowing developers to connect to all L2 scenarios connected to the central system simply by following the standards. For example, a 'cross-domain data encryption tool' developed according to the standard can adapt to DeFi, RWA, and medical scenarios simultaneously without modifying the code, reducing tool adaptation costs by 70%;

• Reusable Revenue Automatic Distribution: After a tool is integrated into the pool, for every use in a scenario, developers can receive ERA sharing (the sharing ratio is dynamically adjusted based on tool usage frequency and value, with a base ratio of 15%-20% of the scenario usage cost), and the distribution is automatically issued through smart contracts without manual intervention. For example, a developer's 'compliance review tool' used by 10 RWA projects can stably earn 12,000 ERA per month, increasing revenue by 4 times compared to one-time development;

• Tool Iteration Incentives: If a tool requires optimization due to feedback from the scenario (such as regulatory rule updates leading to insufficient tool adaptation), developers can receive additional 'iteration rewards' (10% sharing based on post-optimization usage), ensuring that tools continuously adapt to ecological needs.

By the end of 2024, the tool pool has integrated over 280 technical tools, covering 12 core technical scenarios, with the average reuse rate of L2 technical tools increasing from 18% to 62%. The cost of repeated development for developers has decreased by 65%, and more than 150 developers have obtained stable revenue through tool reuse, with average monthly earnings growing by 35%.

2. User Value Mapping System: Cross-scenario credit interconnectivity enhances user stickiness.

To resolve 'user value fragmentation', Caldera has designed a 'user value mapping system' that enables cross-scenario value reuse through 'decentralized identity (DID) + credit aggregation':

• Unified Identity Anchor for DID: Users generate a unique 'ERA-DID' as a unified carrier for cross-scenario value, aggregating users' value data (DeFi credit scores, NFT collection levels, RWA asset holding records) across scenarios under the DID. The data is protected for privacy using zero-knowledge proof technology and is only made available for query upon user authorization;

• Credit and Equity Cross-Scenario Mapping: The system converts users' value data in a single scenario into a 'standardized credit score' and 'universal equity certificate'—for example, a user's 'AA-level credit' in the DeFi scenario can be mapped to 'no-collateral verification equity' in the RWA scenario, and an 'advanced player identity' in GameFi can be mapped to a '20% minting fee discount' in the NFT scenario;

• Value Growth Incentives: The more times users reuse value across scenarios, the faster their credit scores improve, and the higher the levels of rights that can be unlocked (e.g., reusing across 3 scenarios can unlock 'ecological VIP identity' with full fee waivers across scenarios), further promoting user participation across scenarios.

Data shows that after the system went live, the number of L2 users participating across scenarios increased from 1.2 to 3.8, the cost of value migration across scenarios for users decreased by 80%, and the average monthly retention rate of users increased from 55% to 82%, significantly enhancing the stickiness of ecological users.

3. Asset Reuse Channel: Compliance Adaptation + Splitting Mechanism to Activate Hidden Asset Value.

To address the issue of 'low reuse of scenario assets', Caldera has built an 'asset reuse channel' to release secondary asset value through 'compliance adaptation + standardized splitting':

• Dynamic Compliance Adaptation: The channel includes a 'global regulatory rule engine' that automatically matches compliance requirements of target scenarios before secondary circulation of assets (e.g., adapting EU RWA assets to US SEC rules, adapting medical data usage rights to HIPAA standards), generating 'compliance reuse plans', increasing the cross-regional reuse rate of assets from 15% to 70%;

• Non-standardized Asset Splitting: Using smart contracts to split non-standardized assets such as NFT copyrights and medical data usage rights into 'independently reusable rights units'—for example, splitting NFT copyrights into 'commercial authorization rights', 'online display rights', and 'secondary creation rights', allowing users to reuse different rights with businesses, platforms, or creators, thereby increasing the efficiency of secondary value mining by 3 times;

• Reusable Revenue Traceability: Each time an asset generates reusable revenue (such as licensing fees, rents), the revenue is automatically distributed according to the ratio of 'asset owner + original creator' (default owner 70%, creator 30%), ensuring that asset value creators can continuously benefit.

As of the end of 2024, the channel has supported secondary reuse of 6 types of assets such as RWA certificates, NFT copyrights, and medical data usage rights, with the secondary utilization rate of assets increasing from 15% to 58%. The additional revenue generated through reuse exceeds $28 million, and a certain agricultural RWA project's 'farmland revenue certificate' has achieved cross-regional reuse through the channel, with financing scale increasing by 2.5 times compared to single use.

III. Industry Significance: The Transformation of the L2 Ecosystem from 'Value Internal Friction' to 'Efficiency Multiplication'.

Caldera's value reuse model provides a core path for 'cost reduction and efficiency enhancement' for the Ethereum L2 ecosystem, with its industry value reflected in three key dimensions:

Firstly, it reduces ecological development costs and accelerates technical iteration. Through the reuse of technical tools, the average development cycle for L2 projects has shortened from 3 months to 1 month, with development costs decreasing by 65%. Small and medium projects no longer need to invest substantial resources in repeated development of basic tools and can focus on core scenario innovations—by 2024, the number of L2 projects developed through the Caldera tool pool has reached 35, doubling the growth compared to traditional models, significantly enhancing the speed of ecological technical iteration.

Secondly, it enhances user lifetime value and strengthens ecological stickiness. The user value mapping system allows users to 'accumulate once, reuse across multiple scenarios', with the average lifetime value (LTV) of users in the ecosystem increasing by 1.8 times while reducing customer acquisition cost (CAC) for new scenarios—one NFT project reduced new user acquisition costs by 40% and increased the first-month payment rate by 25% by integrating this system, proving that the reuse model can effectively activate user value.

Thirdly, it activates the hidden value of assets and promotes ecological scaling. The asset reuse channel shifts scenario assets from 'one-time transactions' to 'continuous reuse', increasing the liquidity of assets in RWA, medical, NFT, and other scenarios by 3 times, attracting more real enterprises to join—by 2024, 18 companies have achieved asset reuse through the channel, tripling the growth compared to traditional models and increasing the total scale of ecological assets from $500 million to $1.2 billion, truly realizing the conversion of 'idle value into incremental value'.

As the L2 ecosystem shifts from 'scale expansion' to 'efficiency enhancement', 'value reuse capability' will become the core competitiveness of the ecosystem. Caldera's practice shows that only by activating idle resources and breaking scenario fragmentation can the L2 ecosystem achieve 'low cost, high efficiency, and high stickiness' for sustainable development—this is not only Caldera's core value but also the inevitable direction for the Ethereum L2 ecosystem to break through growth bottlenecks.
