PumpRoyale: Web3 Fitness Competition

PumpRoyale is a Web3 fitness competition project that combines USDC as a deposit with fitness challenges, where users can win rewards by completing sports activities.

In PumpRoyale, users around the world can use any amount of USDC as a deposit in regularly held global competitions. During the competition, the system will randomly prompt users to record their completion of a basic fitness activity within 10 minutes. Those who successfully complete the physical activity will receive their deposit, while those who fail to complete it will lose their deposit, which will form a loser fund pool. After each game, the system will randomly select a few people who have completed the fitness activity, and they will receive Allocation of the loser pool.

The project uses smart contracts to hold bets from participating users, as well as refund and distribute funds from the loser pool to a number of randomly selected winners of completed sports events.

IP Infinity: NFT Gamification Project

IP Infinity is a project that combines digital IP assets with the virtual gaming world and creates interactive gaming experiences to bring NFTs to life.

The process starts with the user inputting their Ethereum domain name (ENS). Their NFT is processed and classified by AI and then transformed into game objects, such as characters or equipment. Each game object is assigned statistics that reflect the reserve price and its characteristics. These assets are then integrated into a procedurally generated game world built with Unreal Engine, providing a fascinating and dynamic environment. The project’s unique feature is the IP database, which allows users to share their NFT worlds and use Its unique characters and stories contribute to it.

OmiSwap: A cross-chain trading platform

OmiSwap is an innovative platform that uses AI wearable devices to enable voice-activated blockchain transactions, thereby enabling cross-chain transfers and gas-free USDC sending.

The platform allows users to initiate trades by speaking into their Omi devices, recognizing trigger phrases such as “start trade” and “end trade” to capture user intent. OmiSwap leverages advanced artificial intelligence powered by OpenAI’s GPT model to interpret natural language commands. For example, a user can say “I want to send $5 to Rohan on Polygon,” and the system will convert it into structured transaction data.

The OmiSwap system supports multiple blockchain networks, including Base, Polygon, Arbitrum, and Ethereum. Users can specify the network in voice commands to achieve seamless cross-chain transactions. OmiSwap also uses Coinbase CDP SDK to OmiSwap supports two main types of transactions: transferring cryptocurrencies (ETH or USDC) to other users on the platform, and exchanging currencies between ETH and USDC on the Base network.

UniV4 Backtester: Institutional-grade UniV4 backtester

UniV4 Backtester is a backtesting tool for the Uniswap V4 protocol that can faithfully replay UniV3 events (swaps, minting, destruction) and see how a hypothetical position would perform over time.

The UniV4 Backtester takes liquidity events from a specified UniV3 pool and then replays those events (swap, adding liquidity, removing liquidity) in a hypothetical UniV4 pool that may have a specified peg. This setup enables institutional-grade backtesting analysis, How UniV4 pools perform using the exact liquidity events of real CLMM pools, rather than using aggregated (hourly or daily) historical data, which can lead to inaccurate and unrealistic results. Backtester is able to set up a hypothetical position and backtest the performance of the position over a specified time window.

UniV4 Backtester includes several technologies: using Viem (Node.JS) to obtain UniV3 pool events; using Foundry to fork the Sepolia testnet and perform backtesting.
