September 2025 Update
Program Finances
- Total ARB disbursed to teams to date: 3,233,536 ARB (~35.9% of the 9M ARB budget)
- ARB disbursed in September: 150,000 ARB (~$61,438.57 based on price at the time of transaction). Only 1 milestone payment was processed in September; however there are 6 milestone payments totaling 412,500 ARB that were recently initiated with the Arbitrum Foundation and currently processing.
Submitted Milestones
Similar to August, September was again a slow month with only 5 milestones being submitted. This was due to a variety of factors, as some teams ran into unexpected difficulties involving Stylus while others were traveling for KBW/Token2049. Below are the 5 milestones submitted in September:
Stylus SDK: Building an Assembly Script to WebAssembly Solution by Wakeup Labs
- Milestone 5: Core Development - Pre-QA Refinements (deliverables, payment processing)
- Demo: https://www.youtube.com/watch?v=_kUili8h994
- Developer Documentation: https://as-stylus.wakeuplabs.io/
Walnut: Enhanced Debugging Workflows and Tooling
- Milestone 6: Cargo Stylus Replay command support for debugging Stylus transactions that involve calls to Solidity Contracts (deliverables, in review)
- PR request has also been opened to add Walnut to Cargo Stylus
StylusPort
- Milestone 2: StylusPort: Solana (deliverables, in review)
Moving Stylus by Rather Labs
- Milestone 4: Core Compiler Development: Develop the Move-to-WASM backend, including runtime support and Stylus validation. (deliverables, payment processing)
StylusFuzz
- Milestone 5: Skribe: Fuzz-Testing for Solidity Contracts (deliverables, in review)
Other Stylus Highlights
- Fairblock, the team behind DeBid, has recently been making a push into confidential stablecoins and was highlighted in the Arbitrum blog & on the official Arbitrum X account.
- Castle Capital wrote a piece on Stylus: State of Stylus: Breaking Barriers on Arbitrum. The piece covers stylus at a high level and highlights some of the teams included in the Sprint.
- Delegates interested in seeing some demos from participating teams can watch the recording from last month’s Stylus Sprint call.
Looking Forward
The Stylus v0.10 update is scheduled for beta and full release in Q4. This new version should be a major unlock for Stylus in terms of developer experience as it introduces more support for multi-contract projects and import other contracts directly as Rust crates. These changes will make it much easier to build complex projects and build on existing contracts.
As mentioned in last month’s update, OCL marketing was coordinating with thirdweb on the rollout of their airdrop minter use case, which included materials like developer documentation and marketing materials. A technical case study is completing internal legal review and should be published shortly. Thirdweb has also offered 1-month free for their growth tier to the Arbitrum community by using the promocode: STYLUS-GROWTH. Additionally, a similar technical case study is being prepared for RedStone after observing promising benchmarks from their Stylus implementation.
