The Stylus Sprint application process has concluded with remarkable success, with strong interest from Arbitrum’s talented developer community. The program received an overwhelming response of 147 high-quality submissions requesting approximately 32M ARB, far exceeding the initial 5M ARB budget. This extraordinary demand speaks to the transformative potential of Stylus and its critical role in Arbitrum's technological advantage in the EVM ecosystem.

The submissions were split across two tracks:

• Open Application Track: 89 submissions requesting ~21M ARB
• RFP Track: 58 submissions across nine categories requesting ~10.95M ARB

After a comprehensive evaluation, 17 projects were chosen for their innovative approaches and potential impact on the Arbitrum ecosystem. 

These recipients demonstrated outstanding innovation and alignment with Arbitrum's vision for advancing blockchain technology. The selected projects span crucial areas, including developer tooling, privacy solutions, oracle implementations, and AI integration, strengthening Arbitrum's position as a leader in blockchain innovation.

Over the next 12 months, these selected teams will work alongside the evaluation committee to cement Arbitrum's position as the unrivaled leader in blockchain innovation, pushing the boundaries of what's possible in ways that other EVM chains simply cannot match.

A Note to Applicants

The evaluation committee has been truly inspired and impressed by the incredible quality and innovation across all 147 applications. The depth of talent and creativity in the Arbitrum ecosystem is remarkable. While not every project could be funded in this round, all teams are strongly encouraged to stay engaged.

For teams seeking alternative funding paths, avenues to consider include:

• Joining the Arbitrum Discord to connect with other builders and stay updated on future opportunities
• Participating in future ecosystem initiatives and hackathons
• Checking out The Arbitrum Domain Allocator Offerings Grant Program

The strength of the applications received reflects the vibrant future of the Arbitrum ecosystem. These innovative projects show great promise to develop and thrive, whether through alternative funding routes or independent paths.

Stylus Sprint Selected Recipients

* The following project descriptions are derived from developer submissions and do not constitute endorsement or verification of project claims by Arbitrum Foundation or Offchain Labs.

Open Application Track

Thirdweb Stylus Integration

Stylus capabilities will be brought into thirdweb's full-stack development platform. The team will showcase Stylus's potential through three unique use cases with their partners, making it easier for developers to build and deploy Rust-based smart contracts.

DeBid - Fairblock

Fairblock is revolutionizing onchain auctions by building sealed-bid infrastructure using Stylus. Their solution will serve DeFi, RWA, and tokenization applications, enabling new privacy-preserving use cases that weren't previously possible onchain.

RedStone Oracles

RedStone is developing Rust versions of both pull and push oracles, which will significantly reduce costs and enhance security for Arbitrum's DeFi ecosystem. This implementation will make oracle integration more accessible and efficient for projects building on the platform.

Enclave

As a Compute Provider for secure computation in Encrypted Execution Environments (E3s), Enclave's integration with Stylus will enable private dataset operations while maintaining security. This breakthrough allows for confidential computations without compromising data privacy.

Surety Protocol

This project bridges the gap between fiat and crypto by creating a secured onchain fund backed by multi-currency fiat reserves. Their solution will enhance liquidity access, particularly for non-US/EUR markets, while providing cost-effective on/off-ramps.

Passport XYZ

Expanding their ID verification system, Passport XYZ will enable users to consolidate ID proofs across multiple wallets into a single score, enhancing Sybil resistance and identity verification on the platform.

Open Source Observer

Open Source Observer  is developing an open analytics platform specifically designed to track the growing Stylus developer community, providing valuable insights through open-sourced dashboards.

Remix IDE for Stylus

This implementation will bring Stylus support to the widely-used Remix IDE, enabling developers to develop, compile, deploy, and interact with Arbitrum Stylus contracts through a familiar interface.

RFP Track Selected Winners

Tooling for New Languages

Stylus SDK: AssemblyScript to WebAssembly Solution 

Wakeup Labs is developing a tool that enables developers to compile AssemblyScript into WebAssembly, making Stylus more accessible to JavaScript’s vast developer base.

GUI for the Stylus Cache Manager

GUI for the Stylus Cache Manager

CoBuilders is building an open-source graphical interface for Arbitrum’s Stylus Cache Manager, incorporating automated bidding, real-time notifications, and performance insights.

Enhanced Debugging Workflows and Tooling

Stateful fuzzing of Stylus programs using Medusa:

Trail of Bits’ Medusa, a powerful security testing tool, is being enhanced to support Stylus, enabling researchers to fuzz-test mixed EVM and Stylus contracts in a unified environment.

Walnut: Enhanced Debugging Workflows and Tooling

Major refinements to debugging workflows, filling critical gaps in the developer experience and optimizing multi-contract development across both Stylus and Solidity.

Arbos-foundry

Funding to integrate ArbOS and Stylus support within revm and Foundry, streamlining Solidity development with improved testing frameworks and seamless compatibility with tools like Anvil.

Enhancing Migration Tooling

StylusPort: Stylus migration framework for Solana

A comprehensive framework, toolkit, and documentation suite designed to significantly reduce the complexity of migrating Solana projects to Stylus, demonstrated through real-world implementations.

AI-Powered Onchain Innovations

Angel

A collaborative initiative to develop AI-driven agents on ARC, a Rust-based framework on Solana by Playground, fostering Rust adoption and strengthening Arbitrum’s presence in the AI-agent ecosystem

9 Lives

A next-generation prediction market where AI agents drive and refine decision-making, designed to create a self-sustaining system that evaluates agent performance based on market outcomes.

Education Materials and Developer Resources

Stylus Saturdays Odyssey 

A dedicated blog series exploring the Stylus ecosystem, spearheaded by a prominent advocate. This initiative includes the creation of three distinct Stylus applications, with step-by-step documentation to onboard new developers.
