Immediately following EthCC7, ETHGlobal hosted the ETHGlobal Brussels hackathon from July 12 to 14, featuring a total of 355 projects and offering prize money totaling $475,000.
On July 14, 2024, ETHGlobal Brussels announced its 10 winning projects: BananaBets, Cook some hooks, Zarathustra, Tap Ether, Oh Snap!, Omma Cash, Piggy Wallet, AdFHE, Ephi, and Individuum.
Below are brief introductions to these ten winning projects:
BananaBets
A betting platform allowing ETHGlobal Brussels attendees to predict hackathon winners based on displayed data. Participants can easily join using their NFC wristbands, with bets directly signed by their NFC private keys.

Cook Some Hooks
A tool enabling users to leverage generative AI for easily creating and deploying Uniswap v4 hooks. Users can select their preferred DeFi dApp (e.g., Uniswap or PancakeSwap), choose a trading pair for pool creation, and use an LLM model to generate hook functionality. The generated hooks can then be deployed on any EVM-compatible chain. The project aims to simplify the process of creating and deploying custom v4 hooks, lowering barriers for non-technical users and developers alike, accelerating learning, and serving as bootstraps for more complex hooks.

Zarathustra
A distributed, modular, permissionless artificial intelligence designed to serve as a fully open inference network. Zarathustra consists of three main participants: users, routers, and models, coordinated via smart contracts. Anyone can permissionlessly join and assume any role.
Users interact with a frontend to submit queries—for example, "How many 'r's are in the word strawberry?"—and send them to a smart contract, which processes and broadcasts an event. This event is received by a "router," a high-level large language model responsible for analyzing the query to determine its nature and required task, then assigning it to an appropriate specialized model.

Tap Ether
A simple application that enables sending crypto assets to others with just a tap of a smartphone. Built with React Native and using NFC technology, it allows devices to communicate when brought close together. To receive crypto, users must input their wallet address or connect their wallet. The sender then brings their phone near the recipient’s phone to connect wallets. The recipient specifies the amount, requests a signature, and waits for transaction approval. This process enables fast, secure cryptocurrency transfers via NFC tap.

Oh Snap!
Provides contextual information about smart contracts before transactions, using community voting logic inspired by Vitalik's blog post on X Community Notes algorithms.

Omma Cash
Enables users to send and receive cryptocurrency through WhatsApp chat using natural language prompts—simple enough for grandmothers to use.
All user interactions occur within WhatsApp chats, while all technical operations and on-chain transactions run seamlessly in the background, allowing frictionless transfer of funds, whether crypto or fiat.

Piggy Wallet
A cryptocurrency savings app for children, featuring time-locked savings, automatic USDC exchange, goal setting, task bounties, AI coaching, and parental controls.

AdFHE
A personalized advertising protocol based on Fully Homomorphic Encryption (FHE)—a technique that enables computation on encrypted data without decryption. AdFHE securely analyzes user traits and preferences while preserving privacy throughout the process. Similar to how leading search engines and social media platforms deliver customized content without exposing personal data, AdFHE employs recommendation algorithms that process encrypted user data, enabling targeted ads while safeguarding search history and personal information. By prioritizing privacy and security via FHE, AdFHE sets a new standard for personalized advertising, ensuring users receive relevant ads without compromising confidentiality.

Ephi
A Blinks application inspired by Solana Actions, Blinks, and Forecaster Frames, extending the web3 ecosystem into any web2 environment.
Ephi achieves this through a browser extension that supports embedding mini-context windows anywhere on the web. Phi plugins interpret special bLINKs across the web and render dynamic HTML context windows. The HTML and JavaScript code are retrieved from the IPFS protocol. When an action within the context window is clicked, users are prompted to sign a transaction in their wallet, after which the context window state updates accordingly. Ephi also built a custom Ephi Blink generator, allowing anyone to choose from pre-built presets or create entirely new ones for any imaginable use case.
At the ETHGlobal Brussels hackathon, Ephi developed three distinct Blink examples: 1) A bridging Blink using Chainlink CCIP to transfer USDC between chains. 2) A donation Blink allowing users to contribute to causes. 3) A Blink with a built-in publisher referral transaction, enabling true web3 affiliate marketing.

Individuum
A web task automation marketplace that guarantees task completion according to specified requirements and ensures transparent, secure payments.
Clients can list web tasks on the Individuum marketplace or delegate them to specific parties. This involves providing clear instructions, outlining specific requirements, and setting a fixed price per task. The platform then matches tasks with capable workers. One of Individuum's key advantages is its guarantee of requirement fulfillment. Both parties are protected throughout by Individuum’s integrated payment system. The task poster must lock the specified token amount. Once the task is automatically verified, the worker meeting the requirements automatically receives the tokens. This system prevents either party from cheating.
