Acknowledgment

We extend our sincere gratitude to the Arbitrum DAO, Domain Allocator @Juandi, @Erezedor, and Program Manager @JoJo for their support and guidance through this D.A.O. grant program.

Their trust and encouragement have played a key role in bringing SmartCache to life. This support reflects Arbitrum’s commitment to empowering developers, advancing technical innovation, and fostering a collaborative ecosystem that continues to push the boundaries of decentralized development.

We are truly thankful for the opportunity to contribute to this vision and to build alongside such a forward-looking ecosystem.

About us

Lampros DAO is a open-community of builders and researchers dedicated to strengthening the Arbitrum ecosystem. We focus on developing open-source tools, improving developer experience, and conducting ecosystem research that drives informed, scalable growth within Arbitrum and beyond.

Executive Summary

SmartCache was developed to provide automated gas optimization for Stylus contracts by leveraging Arbitrum’s CacheManager. The system autonomously benchmarks contracts, computes ROI, and submits caching bids both on testnet and mainnet.

Achievements & Impact:

  • 236 contracts under active monitoring (230 testnet, 6 mainnet).
  • Average gas savings: 86.5 % (testnet) and 82 % (mainnet).
  • 236 successful cache bids submitted.
  • 82 developers were actively onboarded as deployers.
  • All components (CLI, Rust crate, backend, dashboard) released as v1.0.0 open source.

Impact of the grant: The funding enabled us to scale from prototype to production, expand mainnet readiness, build a complete developer suite (CLI + dashboard + crate), and run a structured pilot with real users. Without this grant, SmartCache would not have reached adoption by 82 developers and 236 contracts.

Qualitative Impact & Community Feedback

  • Most significant outcome: SmartCache demonstrated that Stylus caching can achieve >80 % gas savings, unlocking real cost reductions and making Stylus contract deployment more attractive.
  • Developer traction: 82 deployers actively used SmartCache during pilot, showing strong demand for automated caching tools.
  • Some of the Community feedbacks:
    • “The dashboard makes it easy to validate savings in real-time.”
    • “CLI tool integrates seamlessly into our dev workflow.”
    • “SmartCache removes the complexity of managing bids manually.”

4. Financial Summary

Grant funds were allocated as follows:

  • Development (60 %) - building CLI, Rust crate, dashboard, backend integration.
  • Testing & Infrastructure (20 %) - hosting costs, monitoring infra, testnet/mainnet gas fees.
  • Documentation & Community (20 %) - docs, tutorials, pilot testing coordination.

No major deviations from the original budget plan. The funds were critical for scaling the project from prototype to production.

5. Future Plans & Continued Ecosystem Alignment

  • Next steps:

    • Expand mainnet coverage to 100+ contracts by Q4 2025.
    • Add Orbit chain adapters to integrate with Orbit SDK.
    • Implement an on-chain fee oracle for dynamic bid risk management.
    • Offer SmartCache as a plug-in for CI/CD templates to boost adoption.

  • Ecosystem alignment: SmartCache will remain tightly coupled with Stylus adoption on Arbitrum, ensuring developers see measurable gas savings.

  • Future partnerships: Discussions ongoing with the ecosystem’s infra teams to bundle SmartCache into dev toolchains.

6. Additional Remarks

  • SmartCache has proven itself production-ready for testnet and limited mainnet use.
  • Backend stability (99.2 % uptime), high bid success rate (96 %), and validate readiness.

The project is positioned to scale alongside Stylus adoption, providing cost savings and better contract performance for the ecosystem.

We’re always open to ideas and feedback that can improve SmartCache for developers across the Arbitrum ecosystem. Feel free to DM me directly here.

Thanks for reading.
