Interaction with ERC721 NFT — Brownie Code
Deploy and interact with an ERC721 NFT smart contract using Brownie.
# contracts/MyNFT.sol
pragma solidity ^0.8.0;
import '@openzeppelin/contracts/token/ERC721/ERC721.sol';
contract MyNFT is ERC721 {
constructor() ERC721('MyNFT','MNFT') {}
function mint(address to, uint256 tokenId) public { _mint(to, tokenId); }
}
# deploy.py
from brownie import MyNFT, accounts
def main():
acct = accounts[0]
nft = MyNFT.deploy({'from': acct})
nft.mint(acct, 1, {'from': acct})
print('Minted NFT ID 1 to account:', acct)Brownie Language Guide
Brownie is an open-source Python-based framework for Ethereum smart contract development, testing, and deployment. It integrates with Ethereum networks and provides a full-featured environment for building decentralized applications (dApps).
Primary Use Cases
- ▸Writing Ethereum smart contracts in Solidity
- ▸Testing contracts using Python-based frameworks
- ▸Deploying contracts to Ethereum testnets or mainnet
- ▸Automating interaction with deployed contracts
- ▸Integrating blockchain contracts with Python backend scripts
Notable Features
- ▸Python-based development environment for Ethereum
- ▸Built-in testing with pytest integration
- ▸Network management for local, testnet, and mainnet
- ▸Support for contract interaction and scripting
- ▸Integration with Ganache and Infura for blockchain access
Origin & Creator
Brownie was created by Matt Lockyer in 2018 to simplify Ethereum smart contract development using Python, providing a familiar developer workflow for testing, deployment, and interaction.
Industrial Note
Brownie is widely used in DeFi, NFT, and other blockchain applications for rapid smart contract development and testing, particularly when Python-based workflows are preferred.
