About

Flow is a layer one blockchain with a powerful smart contract language (Cadence) and full EVM equivalence (any Solidity, smart contract, or protocol that works on Ethereum or an EVM L2 works on Flow). The network was designed from the ground up to enable consumer crypto applications that scale to mainstream audiences and seamlessly connect to digital ecosystems. It is based on a unique, multi-role architecture, and designed to scale without sharding, allowing for massive improvements in speed and throughput while preserving a developer-friendly, ACID-compliant environment. Flow has been architected with a clear vision for the future of consumer crypto, and meticulously designed to address the shortcomings of earlier blockchains to ensure scalability, usability, and efficiency are not simply an afterthought. By incorporating critical protocol-level primitives, such as account abstraction and on-chain randomness, as well a powerful transaction model and scalability without sharding, Flow sets itself apart as a blockchain made for those interested in building apps for widespread adoption and developer-friendly innovation.

Prizes

🚀 Best Killer App on Flow ⸺ $6,000
🥇
1st place
$3,500
🥈
2nd place
$1,500
🥉
3rd place
$1,000
Consumer-oriented “killer apps” have the power to define and lead entire industries by solving real user pain points at scale—think of how ChatGPT made AI accessible to hundreds of millions. Flow is designed for mass adoption and consumer-grade experiences, so we’re looking for the next breakthrough application that can capture the interest of millions (or billions!) of everyday users. This is a very broad bounty and eligible projects include everything from AI Agents and RWA to games and social apps.

Qualification Requirements

• Deploy a smart contract or run transactions on Flow Testnet or Flow Mainnet

🌐 Best Cross-Chain DeFi on Flow ⸺ $4,000
🥇
1st place
$2,500
🥈
2nd place
$1,500
The future of DeFi is cross-chain and Flow is ready to be at the center of it. This prize is for the most compelling projects that unlock cross-chain DeFi on Flow, whether it’s bridging liquidity, creating cross-chain yield strategies, or inventing seamless UX between Flow and other EVM ecosystems. We want to see projects that: • Bridge liquidity between Flow and other chains • Integrate Flow into cross-chain DeFi protocols • Invent new primitives that rely on multi-chain flows of assets or data Build the next generation of DeFi that breaks silos and brings Flow into the global liquidity network.

Qualification Requirements

• Deploy a smart contract or running transactions on Flow Testnet or Flow Mainnet • Your submission must showcase a meaningful cross-chain DeFi use case
