Platzi and Protofire Web3.js-Ethers.js Challenge

Description

This Dapp is a voting system that allows an Ethereum address to vote only once on a binary proposal with a cost of 0.01 ETH choosing its favorite frontend-web3 library: web3.js or ethers.js. For this, the Dapp works in the Görli testnet and is connected with MetaMask.

When a user votes, it can see the result so far (number of positive votes vs. number of negative votes).

Demo of the Dapp

The smart contract is deployed at 0xacfc7725527ba2ee4311574f65e5d76f9f9585e9. You can see it here.

2. Chakra-UI for UI/UX.
