[Final Report] zkArb SDK - Dev Tooling on One and Stylus (D.A.O. Season 3)
The zkArb SDK grantee reports all seven milestones delivered under a $13,000 Arbitrum D.A.O. Season 3 grant.
This is a final report from the team behind zkArb SDK, a toolkit that turns the zero-knowledge proof lifecycle on Arbitrum into a few CLI commands and one JavaScript function, from a Circom circuit to a deployed on-chain verifier. The grant was $13,000 across 7 milestones, approved 24 Sep 2025, in the Dev Tooling on One and Stylus domain. The report says all seven milestones were delivered between 21 Oct 2025 and 7 Jul 2026. Self-reported figures: 57 GitHub stars, 3 forks, 46 commits, two npm packages, three ecosystem integrations (Savique, TempWallets, rekt_ceo), 10+ outside developer contributions, 120+ Telegram community members and 3 pilot-developer case studies. The CLI covers compile, test and deploy commands with options for Arbitrum One, Nova, Sepolia and Orbit chains. Planned next steps are deeper Orbit integrations, a larger template library and proof aggregation input handling. The post links the repository, docs, playground and a full report. Open questions: figures are self-reported by the grantee, and the post does not state an independent review.
