A fast, no-install playground for learning and testing Arbitrum Stylus from your browser.
StylusArena helps developers go from “I’m curious about Stylus” to a working contract interaction in seconds, with live gas comparisons against Solidity.
StylusArena is intentionally narrow: it removes setup friction and answers one practical question quickly — is Stylus worth using for my workload?
| StylusArena | Wizard v2 | |
|---|---|---|
| Best for | First contact, onboarding, workshops | Full development lifecycle |
| Time to first interaction | ~22 seconds | Minutes |
| Setup | Browser only | Project setup + config |
| Gas insight | Front-and-centre live dashboard | Available, not the primary workflow |
| Developer intent | “Let me try this now” | “I’m already building production code” |
| Positioning | Front door | Workshop |
In practice, they complement each other: StylusArena handles discovery and confidence-building, then users graduate to Wizard v2 for deeper implementation.
"Watch the gas savings update live as you type — 88% on heavy compute in real time"
The dashboard updates from template benchmarks and highlights where Stylus performs best (especially compute-heavy workloads).
 Gas Dashboard — live benchmark deltas across templates |
 Dual Editor — Rust and Solidity side by side |
 Template Selector — grouped by developer background |
 Deploy Guidance — Sepolia deployment path |
- Solana Rust developers — You already think in Rust. StylusArena gives you an EVM entry point without making you relearn everything on day one.
- Solidity developers — You can compare familiar patterns directly and make a practical call on when Stylus is worth adopting.
- Web2 engineers — If you’ve worked with APIs, Redis, or backend state machines, the templates feel approachable rather than “blockchain-first”.
- DeFi builders — You get concrete benchmark signals early, before investing time in full protocol architecture.
| Template | Why it matters |
|---|---|
| 🟣 For Solana Devs – PDA Counter | Bridges Solana-style Rust instincts into Stylus with minimal conceptual overhead. |
| 🔵 Migrate from Solidity in 5 min – ERC-20 | Shows a realistic migration path for teams maintaining existing Solidity interfaces. |
| 🟠 Heavy Compute – Fibonacci | Demonstrates headline compute gains (up to 88%) where Stylus is most compelling. |
| 🟢 Web2 Devs – Key-Value Vault | Frames smart contract storage using familiar key-value thinking. |
| 🩷 DeFi Building Block – Multi-Sig Lite | Gives teams a practical starting point for multi-party state transitions. |
- 160+ organic users since launch
- 43% 7-day retention
- 22s median time-to-interaction
- Honorable Mention, Arbitrum APAC Mini Hackathon (Feb 2026)
No paid marketing. Pure organic curiosity.

After grant delivery, StylusArena is designed to support itself through two practical channels: premium advanced templates for teams that want deeper production patterns, and white-label onboarding deployments for Orbit ecosystems that need branded developer onboarding flows.
Contributions are welcome — bug reports, UX polish, template ideas, and docs improvements all help. Please open an issue first for major changes so we can align on scope.
