About

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. We have two new technologies that we'd love you to have a play with: Stylus, which allows you to write your smart contracts in Rust; and Orbit which let you create your own custom blockchains anchored to Ethereum or Arbitrum.

Stylus lets you write smart contracts in programming languages that compile down to WASM, such as Rust, C, C++, and many others. Stylus contracts are over an order of magnitude faster with significantly lower gas fees. Deploy an application on the Arbitrum Sepolia testnet and take advantage of Stylus’ improved speed, cost, and performance. Access features (such as floating point arithmetic, or crypto routines) that are not available in Solidity.

Qualification Requirements

- Deploy your contracts on Arbitrum Sepolia Testnet. - Host your submission in an open source GitHub repository - Is written in Rust using the Stylus Rust SDK (or otherwise compiles to WASM)

🥉

3rd place

$1,500

Best novel use for a project deployed on a custom Orbit chain. Orbit Chains can be a Layer 2 (L2) chain which settles directly to Ethereum, or a Layer 3 (L3) chain which can settle to any Ethereum L2, such as Arbitrum One.

Qualification Requirements

- Must be deployed onto your own Orbit custom chain - Host your submission in an open source GitHub repository

🏆 Best General Project Built on Arbitrum Technology ⸺ $6,000

Up to 4 teams will receive $1,500

Built something cool using Arbitrum that doesn't fit our other categories? This is the one for you. This could be something DeSoc related, like an Arbitrum Farcaster Frame, an eCommerce application, or Governance system. We encourage you to be creative, and show us something we may have never seen before!
