A dapp for creators to deploy their own link aggregator website on IPFS and backed by ENS.

This code will remain as is. We are moving to a separate organization to better manage the code base.

About

This dapp allows a user to create their own link aggregator website on Web3. It is an MVP version of Linktr.ee but entirely decentralized. With the app being decentralized, we are able to give the user complete ownership of their data and the ability to have a site without worrying about hosting.

If you want to build and launch your own aggregator site, visit https://linkens.xyz.

If you trust no one, keep reading on how to launch your own generator.

Principles

Open-source or bust. We believe in using strong copyleft licensing so that lock-in can be avoided.

Users own their work. We believe the user should own as much of the output as possible.

Support without force. We believe in helping users achieve a goal but we do not want to force them to an outcome.

Architecture

There are four key components:

• the site generator dapp
• the custom ENS subdomain registrar
• the user's site
• the site deployer

The dapp is a Svelte SPA that lives on IPFS. It is automatically deployed by Fleek on every push to main.

The smart contract is the controller of the main ENS node and is used to register subnodes. After the subnode is registered, the PublicResolver is updated with any text records that were passed to the function. This process works exactly like multicall (a function on PublicResolver). Once all of the records are updated, ownership is transferred from the smart contract to the msg.sender.

Prior to the registrar being called, an HTML file is deployed to IPFS (via https://web3.storage). This HTML file has the users chosen subdomain hardcoded into the file. When loaded in a browser, the embedded javascript will use the subdomain to pull ENS text records off the blockchain (via Alchemy API).

This HTML file is deployed by Netlify Functions as a way to hide the web3.storage API token and to simplify compiling the main dapp.

Setup

A domain needs to be registered with ENS to use this application. Visit https://app.ens.domains and register a node on either mainnet or a testnet.

This project was originally built as part of the ETHOnline 2021 Hackathon.
