Problem Statement

LegacyLock is a decentralized application (dApp) designed to help users secure and attest important documents, such as academic certificates and employment records, using the Sign Protocol. It allows users to connect their wallets through Web2 methods via the Web3Auth library, facilitating interaction with the dApp. Users can request attestations for their documents and register as attesters to assist in the verification process. Additionally, they can view their attestations, ensuring that all interactions are secured and verified on-chain through the Sign Protocol.

Solution

This application utilizes several key technologies: Next.js, a React framework that enables the development of server-side rendered (SSR) and static web applications; Tailwind CSS, a utility-first CSS framework for efficient styling; Web3Auth, which provides a simple and secure authentication solution for Web3 applications; Ethers.js, a library designed for interacting with the Ethereum blockchain; Pinata IPFS, a protocol and network for storing and sharing data in a distributed file system; and the Sign Protocol, which facilitates the creation and querying of attestations on the blockchain.
