Capybara: An NFT-Powered Fully On-Chain DAO

This is a RainbowKit + wagmi + Next.js project bootstrapped with create-rainbowkit.

Capybara is a decentralized autonomous organization (DAO) designed to enable members to collectively invest in NFT collections. The DAO operates entirely on-chain, leveraging smart contracts to automate the creation and execution of investment proposals. Members of Capybara can propose NFT purchases, vote on these proposals, and the DAO automatically executes successful proposals using its treasury.

Features

• Decentralized Governance: Members propose and vote on governance decisions.

• NFT-Based Membership: Membership and voting power are based on the ownership of specific NFTs.

• Automated NFT Marketplace Integration: Proposals to purchase NFTs are executed automatically if approved by a majority vote.

• Custom NFT Collection: A basic NFT contract is used to mint NFTs for the DAO members.

• Web Interface: A Next.js-based frontend allows users to interact with the DAO easily.

Prerequisites

• Solidity
• Hardhat
• MetaMask wallet
• QuickNode account
• Etherscan account

Setup

Clone the repository to your local machine

 git clone https://github.com/<your_username>/Capybara.git
 cd capybara-dao

Set Up Environment Variables

Create a .env file in contracts directory:

 PRIVATE_KEY="..."
 QUICKNODE_RPC_URL="..."
 ETHERSCAN_API_KEY="..."

PRIVATE_KEY: Exported from MetaMask. QUICKNODE_RPC_URL: QuickNode HTTP Provider link.
ETHERSCAN_API_KEY: Etherscan API key.

Deploy the contracts

Deploy the smart contracts to your preferred network ps:- I have used sepolia test network

  npx hardhat run scripts/deploy.js --network your-network

Take note of the deployed contract addresses, as you'll need them for the frontend configuration.

Frontend setup

Define Constants

Edit the file named constants.ts in the root directory and add the necessary contract addresses and ABIs:

export const CapyNFTAddress = "REPLACE_WITH_YOUR_CONTRACT_ADDRESS";
export const FakeNFTMarketplaceAddress = "REPLACE_WITH_YOUR_CONTRACT_ADDRESS";
export const CapyDAOAddress = "REPLACE_WITH_YOUR_CONTRACT_ADDRESS";

export const CapyNFTABI = []; // REPLACE THIS WITH THE NFT CONTRACT ABI
export const FakeNFTMarketplaceABI = []; // REPLACE THIS WITH THE FAKE MARKETPLACE ABI
export const CapyDAOABI = []; // REPLACE THIS WITH THE DAO ABI

Replace the placeholders with the actual contract addresses and ABI content from the JSON files located in hardhat/artifacts/contracts/.sol.
