YieldStark

Inspiration

The inspiration was to democratize Bitcoin DeFi by creating a single, intuitive platform that maximizes yield while minimizing risk through intelligent automation and cross-protocol optimization, addressing the fragmentation of Bitcoin DeFi

What it does

YieldStark unifies and optimizes Bitcoin DeFi across multiple protocols with intelligent automation and cross-platform yield strategies. It provides a unified interface for Bitcoin DeFi operations, including a non-custodial YieldStark Vault, cross-protocol rebalancing, and Bitcoin staking, all built on Starknet.

How we built it

It was built using a Next.js 15 (React 19) frontend with Tailwind CSS and Zustand for state management, integrating with Starknet (Sepolia/Mainnet). The backend leverages Cairo smart contracts and uses OpenZeppelin's battle-tested standards for security, with core features like the YieldStark Vault and automated rebalancing integrating with protocols like Vesu

Challenges we ran into

Accomplishments that we're proud of

The team is proud of several Key Achievements and Key Features, including: Seamless WBTC deposit/withdraw flow (less than 3 clicks). Real-time yield tracking and 15-25% APY optimization. Gas-efficient batched transactions (40% reduction in gas costs). Non-custodial YieldStark Vault with transparent tracking. Integration with Vesu Protocol and mobile-responsive design.

What we learned

We learnt how to build defi apps on starknet
