Celestial

Celestial is a smart contract wallet that leverages zero-knowledge proofs for authentication

This project is the implementation for Celestial hackathon project at Encode X LightLink Gasless Hackathon

Unlike traditional wallets with a defined owner, Celestial operates on the principle that ownership is established through possession of a valid zero-knowledge proof (zk-proof). This wallet introduces a new paradigm in digital asset management, ensuring privacy, security, and optimal performance.

Features

• Zero-Knowledge Proofs (zk-proofs): Our wallet relies on zk-proofs for ownership validation, providing a secure and private transaction experience. By employing cutting-edge cryptographic techniques, user data remains confidential on the blockchain.

• LightLink Integration: The smart contracts are deployed on the LightLink Pegasus Testnet, offering the advantages of a Layer 2 Ethereum blockchain. Users can enjoy gasless transactions and significantly reduced gas fees compared to the Ethereum mainnet using Enterprise Mode.

• Client-Side Proof Calculation: Noir allows users to generate zk-proofs locally on their devices. This decentralized approach empowers users to control and verify their proofs before interacting with the smart contract, enhancing the privacy and security of their transactions

• Savings: Our Smart Contract Wallet includes an innovative savings feature designed to help users effortlessly grow their savings while managing their digital assets securely. This feature adds a unique dimension to traditional wallet functionalities, promoting financial wellness and goal-oriented saving.

• Daily NFT Minting - The wallet mints daily NFTs for users, each containing the total amount saved in the wallet. This unique feature provides users with a tangible representation of their financial progress.
