Stylus Sprint Highlights
Stylus Saturdays Posts
Contract size limitations and the size of the Stylus SDK have been a prevailing obstacle for developers looking to build with Stylus. While contracts can be split to manage the issue, it increases complexity for developers. Alex has built a smaller version of the Stylus SDK for the community by limiting some of the features.
This post covers the following topics:
- Scaffold Stylus is a project creation tool for a number of contracts and frontends, including a simple ERC20, a ERC721, Chainlink Data Feeds, and Chainlink VRF.
- OpenZeppelin’s v0.30 release is now audited. It includes new features like proxies and sets for efficient storage.
- Dives into the status of the Stylusup revamp. As Entropy mentioned in the August update, we suggested that Alex transition Stylusup from being an on-ramping page to becoming a community ecosystem landing page. The development of the new page is still in progress.
- Short interview with Philip Stanislaus, one of the Co-Founders and Managing Director of Oak Security, the team working on StylusPort.
RedStone
We’re excited to share that the RedStone case study and benchmarks are now published! Delegates can refer to a blog post by OCL & the more detailed technical case study from the RedStone team for more details.
A short summary: Stylus was able to introduce significant gas savings for the EVM RedStone Adapter. Additionally, the Stylus advantage grew with complexity, so the more feeds processed, the greater the relative savings.

Reworking of Scope/Milestones
Since allocating additional ARB to Moving Stylus and Trail of Bits in July, market conditions have once again worsened in October. The committee resumed conversations with a few teams to address shortfalls and have made the following adjustments:
- ArbOS-Foundry by Iosiro: A high priority tool so we are adding 120k ARB across 5 of their remaining milestones. We expect milestones 2 and 4-6 to be submitted very shortly.
- Wakeup Labs (Assembly Script SDK): While the team is close to completing their original scope of work, there are some additional key features that require extra work. 2 additional milestones and 70k ARB has been added to the grant scope.
- Stylus Saturdays: Adding 70k ARB across the final 2 milestones to help cover the audit costs related to the Stylus Dapps Alex is creating.
The committee also worked or is in the progress of adjusting the milestones of the following:
- StylusPort: As mentioned above, Oak Security recommended that milestone 3 be adjusted from a CLI tool to a MCP server based on changes in the current AI landscape. The committee agreed with this recommendation and adjusted the scope/deliverable for the milestone.
- Angel: The Playground team has recently pivoted to an AI product, so the Angel grant is now being carried out by just FairAI and EmberAI. Also making slight adjustments to milestone deliverables based on the advancement in AI tools and practices since the grant was scoped in January.
- 9 Lives: The committee is working with the Superposition team to make milestone adjustments based on changes to their strategy with the 9 Lives prediction market.
Looking Forward
Entropy is looking forward to connecting with several Stylus Sprint teams at Devconnect. RedStone will be presenting a demo of their Stylus implementation at Arbiverse. Wakeup Labs will also be hosting a meet up for Stylus builders that will feature 4-5 technical talks.
As the Sprint enters into its final 3 months, members of the committee are in the early stages of brainstorming what comes after the Sprint and how Arbitrum can continue to support the builders it attracted with this program.
