On October 21, ETHGlobal announced the finalists for the ETHGlobal San Francisco Hackathon. A total of 223 projects participated in the competition, and finally 10 projects stood out, including PumpRoyale, VVLDrizzy and IP Infinity, covering areas such as games and copyright protection.

This article takes you through these 10 projects in detail.

PumpRoyale

PumpRoyale lets users stake USDC in global fitness challenges, complete activities, and win rewards from a loser pool.

In PumpRoyale, users around the world can stake any amount of USDC in regularly held global competitions. During the competition, users are randomly prompted to record their completion of a basic fitness activity within 10 minutes of the prompt. Those who successfully complete the physical activity within the specified time will receive their deposit, while those who fail to complete it will lose their deposit, which will form a loser pool. After each competition, the system will randomly select a small number of people who complete the fitness activity and will receive an allocation from the loser pool.

VVLDrizzy

VVLDrizzy lets creators mint, watermark, and license viral videos while earning revenue. Media organizations can easily license verified content. Powered by Story Protocol and Walrus.

VVLDrizzy (Viral Video Licensor) aims to make it easy for content creators and media organizations to get paid or pay for licensing video content, helping to bridge the gap in Web3 adoption for traditional media organizations.

IP Infinity

IP Infinity turns NFTs into game objects with statistics and integrates them into procedurally generated worlds using the Unreal Engine and AI-driven classification.

IP-Landers is built using AI models, blockchain integration, and game development tools. Meta’s Llama 3.2 visual model analyzes NFT images and generates text descriptions that are classified by the DeBERTa zero-shot classification model to classify them into different types of objects. Unreal Engine powers the game, featuring procedurally generated landscapes and dungeons for a dynamic experience. Story Protocol’s platform allows for collaborative creation without IP disputes.

OmiSwap

OmiSwap uses AI wearable devices to implement voice-activated blockchain transactions, supports cross-chain transfers and gas-free USDC sending, and achieves seamless encrypted interactions.

The platform utilizes advanced AI powered by OpenAIs GPT model to interpret natural language commands. The system supports multiple blockchain networks, including Base, Polygon, Arbitrum, and Ethereum. OmiSwap uses the Coinbase CDP (Crypto Development Platform) SDK to create and manage wallets for users on different blockchain networks. OmiSwap supports two main types of transactions: transfers of cryptocurrencies (ETH or USDC) to other users on the platform, and currency swaps between ETH and USDC on the Base network.

HelloACAI

HelloACAI is an agent-based on-chain collaborative AI infrastructure.

Current general AI helps make recommendations but doesn’t actually save execution time. AI lacks the ability to take appropriate actions based on requests. Multiple AI agents focus on functions such as research, interacting with websites, APIs, calendars, payments, etc. How do you ensure good interactions when AIs collaborate? HelloACAI does this through smart contracts. Interactions with AI agents are governed by these contracts. HelloACAI also provides a registry for AI agents built through smart contracts.

DAOsaster

DAOsaster is a decentralized disaster response system that uses AI agents, drones, and blockchain for autonomous detection and coordination without relying on traditional infrastructure.

The initial phase of the project involves collecting data from local and global agents using drones, which survey and collect key information about the affected areas. This data, including high-resolution video files and photos, is stored on Walrus.

In order to monetize and distribute this valuable content, Story Protocol is used to enable entities such as journalists to mint and use this data. Any profits generated through this process are remitted back to the DAO contract, which is used by AI agents to manage the supply chain. When a disaster occurs, AI agents initiate communication between each other through the SKALE chain, autonomously assigning roles and coordinating actions. They use the Graph Protocol to quickly query and process data, ensuring responsive and efficient operations.

To enhance liquidity and funding for DAOs governed by AI agents, users can tokenize any AI asset (from drones to all-purpose gel devices) to contribute to community resources.

Chain Waves

Chain Waves allows users to watermark audio files and secure them on the blockchain, ensuring proof of ownership, royalty tracking, and automated dispute resolution for creators.

Working principle:

• Mint Your IP: Upload content and mint it as an NFT.

• Collect Royalties: Automatically receive royalties when your IP is used, according to the terms you set.

• Dispute Resolution: If you discover unauthorized use, initiate a dispute process backed by a legally binding contract.

• Using IP as loan collateral

Key benefits:

• Legal Support: Story Protocol’s smart contracts provide a legal basis for intellectual property rights.

• Transparent Tracking: All usage and royalty transactions are recorded on the blockchain for full transparency.

• Efficient dispute handling: Use the dispute system to quickly handle and resolve intellectual property infringement issues.

BuildBlocks

BuildBlocks creates drag-and-drop smart contract components that allow anyone to develop, compile, and deploy audited contracts on Rootstock, making Web3 development simple and secure.

BuildBlocks is built using the standard NextJS, Tailwind stack, and also uses an injectable wallet, Rootstock deployment and test network, the SolC compiler for automatic Solidity contract compilation, and SIDAIs RAG pipeline generation service.

Uni V4 Backtester

Uni V4 Backtester is an institutional grade Uni V4 backtester that can accurately replay Uni V3 events (Swap, Mint, Burn) to see how a hypothetical position would perform over time.

Uni V4 Backtester uses a variety of technologies to make this backtester: Viem (NodeJS) is used to obtain Uni V3 pool events; Foundry is used to fork the Sepolia testnet and perform backtesting.

Betsy

Betsy is a Web3 betting platform on Skale with XMTP-powered syndicated betting messaging. USDC funds are transparently processed via smart contracts, and AI helps determine outcomes. Bets are completed and settled on-chain, ensuring secure, trustless, and engaging syndicated betting.

After creating a bet, group members can chat within the platform, agree or disagree with the predictions, and place their bets. Once the bet is finalized, the smart contract automatically transfers the funds. In addition, the platform uses AI to analyze real-time sports data and help determine the outcome of each bet. After the game, the AI checks whether the predictions were correct, and the smart contract distributes the winnings or losses accordingly.
