At the end of October, Flare partnered with the ETH London Hackathon, powered by Encode Club, to allow the Ethereum community to hack in-person with global web3 talent – and win bounties.
The event gathered over 1,000 web3 developers from across the globe, from university newcomers to seasoned builders, all there to demonstrate the potential of blockchain technology.
For three days, the venue didn’t stop buzzing with the kind of vibrant and friendly energy perfect for innovation and collaboration.
The event wasn’t just about competition. It was a celebration of what can be achieved in the ever-expanding Web3 space. With a prize pool exceeding $90,000, we saw an impressive array of projects, tackling everything from decentralized finance to quantum oracles.
Filip Koprivec, our Senior Solidity Engineer, delivered an insightful workshop on the Flare Time Series Oracle (FTSO) and use cases of Flare.
Other highlights included Google’s workshop on deploying blockchain nodes using their Blockchain Node Engine (BNE), as well as a fireside chat with Robby Yung, CEO at Animoca Brands, discussing the future of Web3 in the gaming industry. And let’s not forget the most wanted merch around — pink Flare hoodies.
Almost 100 people took part in the Flare tracks, building an impressive 44 projects on our stack. We also made countless connections with community members, potential partners, and aspiring developers eager to explore what Flare has to offer.
What’s Being Built with Flare?
For the ETH London Hackathon, the primary focus of our tracks was the use of the Flare Time Series Oracle (FTSO). Here are some of the winning projects that utilized the FTSO:
1. SwapGuard
SwapGuard is a price-protected DEX on Flare, utilizing circuit breaker-guarded swaps to make it gas-efficient, all made possible by the FTSO.
Codebase: https://github.com/Markeljan/swapguard
Developers: Valerio Fichera and Markeljan Sokoli
2. Flare Stable Coin
Flare Stable Coin is an exogenously collateralized stablecoin constructed from a token contract owned and controlled by an “engine” contract. The engine contract leverages the FTSO for price feeds. FSC maintains its stable price by enabling users to mint an appropriate amount equivalent to their deposit based on FTSO prices, and it also allows other users to liquidate positions if collateral prices drop too low.

Developer: Palm Civet
3. SocialDefi
SocialDefi is a platform that offers various features to enhance transparency in the crypto space, allowing users to stay informed about market changes and follow other investors to track their profit and loss. The project uses Flare on multiple fronts. It uses the FTSO to fetch price feeds, and, through the Coston API, accesses user data.

Developers: Indi Sofyar
4. Hayek index Token
“Hayek” is an index token representing a combination of ETH and BTC, and this project allows for the swapping of tUSD to Hayek, The oracle price is used in the process, leveraging Flare’s FTSO for accurate pricing feeds.
Codebase: https://github.com/BigBangInfinity/hackathon/blob/main/hayek
Developer: Ching-Hwa Eu
5. Quantum Oracles
Smart contracts execute quantum programs, storing and aggregating the results of quantum programs on the Flare network, highlighting external data’s importance and value. Users can pay for their quantum jobs using cryptocurrency, effectively creating an end-to-end decentralized ecosystem for quantum computing.
Codebase: https://github.com/Quantum-Oracles
Developers: Jessica Pointing, Yash Goyal and Jan Ole Ernst
These innovative projects, along with others like Mayk, Tixo, ChatChampion, Loyalty NFT and OracleVote deployed on Flare, showcase the immense potential of the Flare platform.
We also want to give a shoutout to our no-code winners who impressed us with their creative and educational projects:
- Andrzej Mackowiak created a long blog post about Flare, describing its core protocols, the FTSO and State Connector, and its fundamentals clearly and engagingly. You can read his post here.
- Darigov Research put Flare’s Glossary into a format that can be easily learned using Anki, a flashcard app. You can download their flashcards here.
