WalletConnect

$5,000

About

WalletConnect is the connectivity layer for the financial internet, open infrastructure trusted by 700+ wallets, 70,000+ apps, and millions of users. At ETHGlobal Cannes we have two tracks: build onchain payment experiences with WalletConnect Pay, or build seamless multichain wallet connectivity using AppKit. One network, two ways to build.

Prizes

🌐 Best App built with Reown SDK ⸺ $1,000

Build an app that uses Reown Authentication or connects users across at least two distinct chain ecosystems — EVM, Solana, Bitcoin, TON, or TRON — using the AppKit SDK. We're looking for real-world use cases with great on-chain UX. DeFi, payments, gaming, and consumer apps are all welcome.

Qualification Requirements

⚪️ Must use Reown AppKit. ⚪️ Must connect and transact across at least two distinct chain ecosystems (e.g. EVM + Solana, EVM + Bitcoin — not just two EVM chains), or use Reown Authentication. ⚪️ Working demo required: a public GitHub repo and a video showing and explaining the functionality and the problem or innovation being built.
