Flow Blockchain Crowned 'Most Built On L1' at ETHGlobal Cannes Hackathon

Cannes, France – The Flow blockchain, developed by Dapper Labs, emerged as the platform with the "most built on L1" projects at the recent ETHGlobal Cannes Hackathon, which concluded on July 6, 2025. This achievement underscores Flow's growing appeal to developers, attributed to its unique technical features and dedicated builder support. The official Flow.com account stated in a tweet, "You get the most built on L1 at the @ETHGlobal Cannes Hackathon," highlighting 13 projects as examples of the diverse applications being developed on the platform.

Flow is a fast, developer-friendly, and scalable Layer 1 blockchain specifically designed for consumer-facing applications, including games, digital collectibles, and decentralized apps. Unlike many other blockchains, Flow utilizes a unique multi-role architecture that enables high throughput without sharding, aiming for mainstream adoption. It supports EVM equivalence, allowing developers familiar with Solidity to easily build on the network, alongside its native resource-oriented smart contract language, Cadence.

Key features cited for Flow's success at the hackathon include gasless transactions, which streamline the user experience by removing transaction fees for end-users, and built-in randomness, crucial for gaming and NFT applications. The platform also offers native account abstraction, simplifying user onboarding and interaction. Furthermore, Flow's commitment to "hands-on support" was evident through initiatives like a dedicated Hacker Breakfast and workshops at the event, providing direct access to Flow experts for participating teams.

The ETHGlobal Cannes Hackathon, which offered a total prize pool of $275,000, challenged developers to build innovative Web3 solutions from scratch over three days. Flow's strong showing at Cannes follows similar successes at previous ETHGlobal events in Singapore, San Francisco, and Bangkok, where it consistently ranked as a top platform for builder activity. At ETHGlobal Bangkok, for instance, 99 applications were built on Flow, with nearly one-third of all submissions to judges utilizing the blockchain.

This consistent performance at major hackathons positions Flow as a preferred choice for developers looking to build scalable and user-friendly decentralized applications. The emphasis on developer support, combined with its robust technical foundation, is proving effective in attracting talent and fostering innovation within the Web3 ecosystem, particularly for consumer-oriented dApps.
