CFWeb3 is a Web3 demo application. It uses Hardhat and Solidity to create an Ethereum smart contract. This code is a proof-of-concept showing how to build Web3 applications with Cloudflare, and should not be used as a production example.

The contract offers 2048 tokens which can be minted via the frontend Svelte application. The entire app runs on the Rinkeby test network.

A live version of this demo app can be found at cf-web3.pages.dev.
