Several submissions emphasized verifiers, proof workflows, and “hybrid compute” patterns, where heavy logic resides off-chain or in specialized circuits, while Stylus verifies and coordinates on-chain state. ### Demo Day lineup (as presented) 1. KOKI’O (Alumni Highlight) 2. Quiproof 3. Heirloom Inheritance Protocol (Stylus Track) 4. Confidential EVVM (zkEVVM) (Stylus Track) 5. Dreamteam zkgame 6. Torresm (Stylus Track) 7. Multi-point KZG Proof Verification for the EVM * * * ## Milestone 6: Lecture Videos (Final Cut) **General deliverables:** Workshop videos (raw + final cut), slides, and materials. Video descriptions with chapter timestamps and links to code; there were no new repos committed by the mentor, only live lessons. **Outcomes:** Final cuts are published as a single YouTube playlist. Each video includes a complete description, which is timestamped with chapter markers where applicable. **Playlist:** [https://www.youtube.com/playlist?list=PLDQrbdlvR\_eEKv42YTC1DNzgdbv-x\_NOs](https://www.youtube.com/playlist?list=PLDQrbdlvR_eEKv42YTC1DNzgdbv-x_NOs) **Materials/slides used (titles + dates):** - **Intro to Stylus, 28 Oct 2025** Materials Used: - **Working with Stylus CLI, 29 Oct 2025** Materials Used: - **Stylus Data Types, 30 Oct 2025** Materials Used: - **Uniswap fork in Stylus, 03 Nov 2025** Materials Used: - **Stylus Speedrun (1 & 2), 06–07 Nov 2025** Hosted without slides following these Stylus Speed Run Challenges: * * * ## Milestone 7: Final Report ## 1) Executive Summary ### What is Invisible Garden? - A university-like experience for Ethereum devs - A focused pop-up city for neurodivergent builders - A collective of world-class mentors - A community fostering deep, lasting connections - A registered NGO dedicated to Public Goods ### What Invisible Garden is NOT - A crypto holiday with no tangible outcomes. ### Summary of Achievements & Impact on Arbitrum Invisible Garden delivered **6 public Arbitrum-focused lectures** (≈1.5 hours each) plus **on-demand mentorship sessions** , supporting **53 selected builders** through a structured learning + shipping loop for Arbitrum Stylus (Rust/C++ smart contracts interoperable with Solidity). The program culminated in a public Demo Day and produced an auditable set of open-source artifacts: a public GitHub org, standardized project templates, progress labels, and public session recordings. Half (3/6) demo day-selected projects were part of the Arbitrum Stylus track. ### How the Grant Funding Helped The **$25,000** grant enabled Invisible Garden to run a focused Stylus residency and to: - Deliver structured sessions (academic content + hands-on mentorship), - Maintain public evidence artifacts (repos, templates, labels, and recordings), - Support the student project pipeline and incentives (including Stylus qualification + prizes). * * * ## 2) Performance Against KPIs | KPI / Output | Projected (from proposal) | Actual (from delivered info) | Evidence | | --- | --- | --- | --- | | Workshops (Arbitrum-focused) | ~9 sessions | 6 public lectures (~1.5h each) + on-demand mentorship sessions | [Academic Schedule - Google Sheets](https://docs.google.com/spreadsheets/d/17IjHVzJyDOFugfGZLSOILVvgoGLNjCQrgrSnXmJlsmI/edit?gid=0#gid=0) | | Target attendees (builders) | ~65–75 | 54 builders in attendance (+ external guests;

We don’t just run a cohort and leave; we maintain the alumni network as active contributors. Future cohorts will build directly on top of the open-source repositories created here (e.g., extending the Heirloom Protocol with new recovery mechanisms), creating a compounding library of Stylus-native tooling that grows with every residency. ### Follow-on funding/partnerships Follow-on partnerships and co-funding opportunities between Invisible Garden and Arbitrum in 2026 could involve our signature devcity (“hard-mode”), plus lightweight, year-long collaborations across multiple touchpoints to engage our builders alumni network online and in-person. We will continue hosting a core residency in India ahead of Devcon 8, where Arbitrum could become one of our lead partners, and we’ll host smaller specialized events (e.g., masterclasses) leading up to it. Our main value offer is steady developer engagement and a recurring feedback loop around what builders actually struggle with as they continue to ship. * * * ## 6) Additional Remarks ### Program Scale (context) **IG Chiang Mai 2024** - 830 applications → 160 developers accepted - 80 on-site developers from 15+ countries - 83 workshops, 40+ mentors - 34 open-source projects; 22 graduated **IG Buenos Aires 2025** - 1038 applications → ~300 accepted - 54 on-site developers from 25+ countries - 57 academic sessions (~46 hours), 40+ mentors - 43 open-source projects initiated; 65% graduated **IG Buenos Aires’ Arbitrum Stylus (zoom in)** - ~50 on-site developers from 25+ countries - 70+ external guests signed up for Demo Day; 700+ for the closing ceremony; plus additional attendance across three weeks of open sessions - 6 academic sessions with lead mentor Alok Kumar (GitHub: surfer05) - ~9 hours of content (subset recorded and published) - Dedicated mentoring sessions to builder teams - 10 Stylus-focused projects initiated; 6 formally qualified under strict Stylus-native criteria (Rust/C++) ---

Solid execution and detailed artefacts, but the report stops short of the key DAO question: what was the cost per active Stylus builder and per qualified Stylus project, and how will the Day 30/60/90 commitments be reported back to the DAO in a verifiable way? @invisiblegarden ---
**Author:** ![JulianCross](https://yyz1.discourse-cdn.com/flex029/user_avatar/forum.arbitrum.foundation/juliancross/32/16561_2.png) [@JulianCross](https://forum.arbitrum.foundation/u/JulianCross)\ **Post date:** [July 30, 2026, 2:11pm UTC](https://forum.arbitrum.foundation/t/invisible-garden-arbitrum-stylus-tooling-residency-final-grant-report-detailed-milestones/30374/5 "2026-07-30T14:11:53Z")
@MconnectDAO You have correctly identified the structural tracking gap that is currently paralyzing EVM DAO treasuries. @invisiblegarden The qualitative artifacts here (YouTube playlists, Google Docs, GitHub repos) are excellent for community building. However, from a capital allocation perspective, self-reported spreadsheets cannot function as scalable, verifiable KPIs for a DAO managing hundreds of millions in ARB. To answer the “Cost per Active Builder” and “Day 30/60/90 Retention” questions without drowning grantees in administrative paperwork, the ecosystem requires a bespoke, automated Stylus Developer Impact Oracle. To verifiably track Arbitrum developer residencies and Stylus onboarding, the DAO needs a programmatic Dune/SQL architecture that tracks: 1. The Day 30/60/90 Stickiness: Indexing the specific wallet addresses of cohort developers and tracking their on-chain contract deployments on Arbitrum Stylus 30, 60, and 90 days after the grant ends. 2. True Cost Per Builder: Automatically dividing the grant volume by the number of developers who actually pushed production-ready Stylus code post-event, generating a live ROI matrix. 3. The GitHub-to-Chain Vector: Cross-referencing repository commits with actual on-chain gas expenditure to filter out “hello world” spam and identify high-value protocol engineers. Grantees should build; the DAO’s infrastructure should automatically track the impact. If the Arbitrum delegates and Domain Allocators are looking to standardize this level of enterprise-grade, automated tracking across all future developer grants, I can scope the operational mandate to architect this customized dashboard for the ecosystem. ---

Agreed with JulianCross this confirms the structural tracking gap I flagged above. The qualitative artifacts (YouTube playlists, GitHub repos, Google Docs) are great for community visibility, but self-reported spreadsheets simply cannot serve as scalable, verifiable KPIs for a DAO deploying capital at this scale. To answer “Cost per Active Builder” and Day 30/60/90 retention without burying grantees in manual reporting, we need a programmatic Dune/SQL-based Stylus Developer Impact Oracle that tracks: 1. Day 30/60/90 stickiness — index cohort wallet addresses and track on-chain Stylus contract deployments post-grant. 2. True cost per builder — divide grant volume by developers who actually ship production-ready Stylus code, generating a live ROI matrix. 3. GitHub-to-chain vector — cross-reference commits with real gas expenditure to filter out low-effort activity and surface genuine protocol engineers. Grantees should focus on building; the DAO’s own infrastructure should handle impact tracking automatically. Happy to help scope this as a standardized mandate across future Domain Allocator grants if there’s appetite for it. @JulianCross ---

Hi @MconnectDAO, @JulianCross, thank you for reading the report and for the questions. I answer on behalf of Invisible Garden. To keep this thread readable, the full detail, with the tables and every transaction, is in a public closure report: [Arbitrum Stylus Residency - Grant Closure Report (Aug 2026) - Google Docs](https://docs.google.com/document/d/1oQsFipTo4Df0oHSJJEUqJ6Vov5DgZkA19G3xJFcFnSc/edit) Here the direct answers. **Cost.** The grant was $25,000 and the residency worked with 54 builders, the KPI table figure, backed by the [daily check-in sheet](https://docs.google.com/spreadsheets/d/1RiMx_mwG3v7WimZMlZ0Ljgx2v0ByaDyifKiTzyIua70/edit?usp=sharing). That gives $463 per builder, $676 per project initiated (37), $2,500 per Stylus track submission (10), and $4,167 per qualified Stylus project (6). These figures count only the Arbitrum grant. The full residency cost around $100,000, funded from several sources. **Bounties.** The $5,000 pool is fully distributed, $5,002 on-chain, and the closure report carries the per-project table with every transaction link. The payments went out later than they should have, that was our internal mistake during a team transition, and it is now settled. **Day 30, 60, 90.** The [Stylus Reference Index](https://github.com/invisible-garden/arg25-Projects/blob/main/STYLUS_REFERENCE_INDEX.md) is now published. It indexes the six lectures, the available slides, the curriculum, and the reusable code in the student repositories, checked entry by entry against the repo contents. The technical write-ups are published too: [Heirloom Inheritance Protocol](https://github.com/invisible-garden/arg25-Projects/blob/main/writeups/heirloom-inheritance-protocol.md) and [Confidential EVVM](https://github.com/invisible-garden/arg25-Projects/blob/main/writeups/confidential-evvm.md), architecture case studies checked against the shipped code, with each project’s limitations stated plainly. The Stylus lectures and the patterns from this cohort will be part of the base curriculum for the next Invisible Garden edition, still to be scheduled. Meanwhile everything is already usable without waiting for us: the videos, the code and the write-ups are public for anyone to reuse. **On verifiable reporting.** Everything we produce is public: the [GitHub org](https://github.com/invisible-garden), the [lecture recordings](https://www.youtube.com/playlist?list=PLDQrbdlvR_eEKv42YTC1DNzgdbv-x_NOs), the [evidence spreadsheets](https://docs.google.com/spreadsheets/d/1sbI4ck4teFMCabmTScH7CpFZZe_uHdfSPDoKoWbaDrk/edit?gid=0#gid=0), and this thread, where we will keep posting updates. On automated program-level tracking, that design belongs to the DAO and the program team. One correction for the record: the third transaction link in my July message pointed to a look-alike scam transfer that appeared in our Safe history minutes after the real payment, a common address-poisoning trick. I have edited that post with the [correct transaction](https://arbiscan.io/tx/0x6897be749d30cdcf47cef680de1ea05c5ec7dae63f0d6f81dc6e810d5203325b), and the funds always went to the right wallet. Details in the closure report. Leo Lara Invisible Garden ---

Hi all, a short update from our side. The program is fully closed out on the Invisible Garden side. The bounty pool is distributed, the Stylus Reference Index and the two Day 60 write-ups are published, and the closure report with every transaction is linked in my previous message above. The remaining step in the program flow is the completion survey for Milestone 7. We are ready to do it whenever it suits the DA team, by call or in writing. Thank you to the Domain Allocator team for the guidance. Leo Lara Invisible Garden
