About

NOTE: THES BOUNTIES ARE MOSTLY FOR PROJECTS USING STYLUS (RUST), CHECK DETAILS OF THE BOUNTY CAREFULLY Designed with you in mind, Arbitrum is the leading Layer 2 technology that empowers you to explore and build in the largest Layer 1 ecosystem, Ethereum. Arbitrum Stylus is a groundbreaking upgrade to Arbitrum chains that adds a WebAssembly (WASM) Virtual Machine (VM) to enable developers to write their smart contracts in languages beyond Solidity, such as Rust, C, and C++ while still fully interoperable and composable with Solidity smart contracts. This upgrade opens the door for a wider range of developers, especially those with existing skills in languages, to seamlessly transition into blockchain development on Ethereum-compatible networks. By supporting familiar, more mature programming languages, Stylus accelerates onboarding, reduces learning curves, and broadens the scope of possibilities for efficient, high-performance decentralized applications.

Prizes

🏆 Stylus General Track ⸺ $7,500

Up to 3 teams will receive $2,500

THIS IS A BOUNTY FOR PROJECTS USING STYLUS (RUST), JUST USING SOLIDITY DOES NOT QUALIFY This is the track for general, non-DeFI applications built using Arbitrum Stylus. There are lots of different types of things we'd love to see you build, so here are some ideas: General: - Gaming - Social apps - Art / Culture apps - Cross-chain interoperability Ecosystem interoperability / Tooling - Port over projects from other chains using Rust(-like languages) - e.g. Solana, Aptos, Stellar - AssemblyScript SDK - GUI for the cache manager Cryptography / AI / Compute: - AI - Cryptographic proofs that do not exist on the EVM - FHE - MPC - ZeroKnowledge proofs Stylus on Orbit: - Either on your own Orbit chain, or an existing Orbit chain, e.g. ApeChain

Qualification Requirements

- Must have a Stylus smart contract deployed on an Arbitrum chain (Arbitrum Sepolia, Arbitrum One, Arbitrum Nova, or your own Arbitrum Orbit chain) - Must not be DeFi (because there is a separate prize category for DeFi)

💰 DeFi on Stylus ⸺ $8,000

Up to 2 teams will receive $4,000

THIS IS A BOUNTY FOR PROJECTS USING STYLUS (RUST), JUST USING SOLIDITY DOES NOT QUALIFY Arbitrum is the leading L2 for DeFi applications. Now you can build more advanced and novel DeFi applications using new languages, like Rust, with Stylus. The DeFi on Stylus prize celebrates groundbreaking projects that harness Arbitrum Stylus to build advanced DeFi applications on Arbitrum. This prize rewards developers who leverage the flexibility of Stylus and the new WASM VM, using languages like Rust, C, or C++, to create powerful, unique, and efficient financial solutions that push the boundaries of what’s possible in decentralized finance. Eligible projects may include innovative lending protocols, liquidity solutions, cross-chain interoperability tools, or other financial products that demonstrate novel approaches to security, scalability, and usability. This prize aims to inspire developers to reimagine DeFi by utilizing Stylus for high-performance and feature-rich applications that can serve both seasoned and new DeFi users.

Qualification Requirements

- Only awarded to DeFi or DEX use cases with Stylus, e.g. Uniswap V4 Hooks - Must have a Stylus smart contract deployed on an Arbitrum chain (Arbitrum Sepolia, Arbitrum One, Arbitrum Nova, or your own Arbitrum Orbit chain)

🌐 Orbit, BoLD, Timeboost ⸺ $2,000

Up to 2 teams will receive $1,000

The Orbit, BoLD, Timeboost Prize invites developers to push the boundaries of Arbitrum’s newest technologies: Orbit, BoLD (Bounded Liquidity Delay), and Timeboost. This prize is for projects that creatively showcase these advanced, infrastructure-focused tools and/or applications that leverage these novel technologies or augment them in some way (e.g. minimizing trust, etc) Using Orbit, developers can achieve unmatched scalability and customizability for their own chain; BoLD unlocks permissionless validation & paves the path for decentralized validation (and the economic structures that could be built on top); and Timeboost offers a new way for chains to handle MEV at the protocol layer. Whether you're building DeFi, gaming, social, or cross-chain interoperability projects, this is an opportunity to leverage Arbitrum’s cutting-edge stack in ways not done before. Example ideas include: - New in-protocol or app-specific ways for AMM pools to retain MEV with Timeboost - Applications requiring Orbit’s customizability, like blazing fast 100ms block times, rapid ~1-minute withdrawals with AnyTrust, 3rd party DAs (e.g. Avail, Celestia, EigenDA), high throughput (10M Gas/s), or increased contract size limits. - Cross-chain interoperability solutions that use Arbitrum Orbit for novel L3-to-L3 interactions - New tooling with BoLD for decentralized validation, such as staking designs, auto-pooling of funds to secure a chain, or fraud-proofing WASM in other use cases
