Linktree Dapp

LinkTree DApp (Decentralized Profile Manager)

The LinkTree DApp is a decentralized application built on the Polygon Mainnet that allows users to create and manage their personal profile links in a fully Web3-enabled environment.
Instead of traditional email or password authentication, the app uses MetaMask wallet connection for secure login and identity verification, ensuring that users have complete ownership and control over their data.

Once connected, users can:

Add, edit, and update their social and external links (like Instagram, Twitter, GitHub, or website URLs).

Customize their public profile by selecting from different profile view templates.

Instantly share their public LinkTree-style page, which displays their chosen links and profile theme.

Have all actions such as link updates and profile edits securely associated with their wallet address on the blockchain.

This project was developed entirely using wallet-based authentication without any centralized login or database, demonstrating how Web3 principles can replace traditional user management systems.
