COOK SOME HOOKS

A tool allows users to easily create and deploy Uniswap V4 hooks by generating AI.Users can choose their favorite DEFI DAPP (such as Uniswap or Pancakeswap), choose the currency pair of the pool, and then use the LLM model to generate the HOOK function.The generated hook can be deployed on any compatible EVM chain.The project aims to simplify the process of creating and deploying custom V4 hooks, reducing the obstacles of non -technical users and developers, so that they can learn faster and use it as a guidance program for more complex hooks.

Zarathustra

A distributed, modular, and artificial intelligence without permission is designed to become a completely open reasoning network.ZARATHUSTRA is composed of three main participants: users, routers and models.These participants coordinate through smart contracts.No one can join and play any of the roles.

The user interacts with the front end to submit the query, for example, “How many R are in the word Strawberry?”They submit the inquiry to smart contracts, smart contract processing and broadcasting events.This incident was accepted by “router”.Router is a high -level large language model that is responsible for analyzing and query to determine its nature and the need for tasks.According to the analysis results, the router assigned the task to the appropriate special model.

Tap ether

TAP Ether is a simple application. You can send encrypted assets to others as long as you touch your phone gently.It is built with React Native and uses NFC technology to allow devices to communicate when approaching each other.Using TAP Ether, those who receive encrypted assets need to enter their wallet address or connect to their wallets.The sender then connects their mobile phones to the receiver’s mobile phone to connect their wallet.The receiver specifies the amount, and then requests the signature and wait for the transaction signature.This process can transfer cryptocurrencies very quickly and safely using NFC to touch the phone.

Oh Snap!

Prior to the transaction, the background information about smart contracts is provided, and the logic of using community voting is inspired by Vitalik’s blog on the X Community Notes algorithm.

Adfhe

A personalized advertising protocol based on a full -time encryption (FHE).Adfhe uses full -state encryption (FHE) to achieve personalized advertising. FHE is a technology that can be calculated on encryption data without decryption.This means that ADFHE can securely analyze user characteristics and preferences to ensure privacy in the whole process.It is very similar to providing customized content with leading search engines and social media platforms without leaking personal information. Adfhe uses a recommendation algorithm.The algorithm processing encrypted user data enables the platform to provide targeted advertisements while protecting personal search history and personal information.Through FHE preferential considerations of privacy and security, ADFHE has set up new standards for personalized advertising to ensure that users receive relevant advertisements without sacrificing confidentiality.

Demonstration address: No

Ephi

Blinks application.Inspired by Solana Actions and Blinks and Forecaster Frames, EPHI Blink extended the Web3 ecosystem to any web2 environment.

EPHI creates a browser extension to achieve this, which supports any position on the network into the mini context window at any position on the network.The PHI plug -in can explain the special blink at any position on the network and present a dynamic HTML context window.HTML and JavaScript code are retrieved from the IPFS protocol.When clicking the operation in the context window, the system will prompt users to sign a transaction in their wallet. After successful, the status of the context window will be changed accordingly.EPHI also constructs a custom EPHI Blink generator. Anyone can choose from the presets that have been constructed, or create a new preset for any case you can think of.

On ETHGLOBAL BRUSSELS hacker marathon, EPI has built three different Ephi Blink examples.1. Use Chainlink CCIP protocol to connect USDC from one chain bridge to Blink from another chain.2. Donate Blink, users can donate to a certain business.3. The built -in Blink publisher invites the Blink of the transaction to achieve the real Web3 alliance Blink.

Individuum

A network task automated market, which guarantees to complete the task according to the requirements of the requirements and ensure transparent and safe payment.

Customers can list their network tasks in the INDIVIDUM market, or assign them to the party where they want to share the task with them.This involves providing clear instructions, overview specific requirements and setting fixed prices for each task.Then, the platform matches the task with the workers who can efficiently complete the task.One of the main advantages of Individuum is that it guarantees the requirements for completing the settings.Throughout the transaction, both parties will be protected by IndiVIDUUM integrated payment system.People with a list must lock the number they specified in the list.Once the task is automatically verified, workers who meet the task requirements will automatically receive tokens.With this system, both sides cannot cheat.
