This is a simple boilerplate React application showing how to leverage ERC-7529 to directly inspect DNS TXT records to discover smart contracts on a public blockchain and verify the assoication of the smart contract with the DNS domain.
See handleKeyPress function in DomainInput.tsx for a running example of how to use @snickerdoodlelabs/erc7529 in your application to discover smart contracts using only DNS domain names.
You'll need a browser extension installed that injects an ethereum provider (window.ethereum), like Metamask. Next, you'll need to toggle the active network in your extension to the target network you are interested in, (like Fuji testnet). Then type in the name of a domain (like snickerdoodle.com) and see if any contracts are associated with that domain on the network your wallet is connected to.
You can play with this applciation locally.
git clone https://github.com/SnickerdoodleLabs/Testbed-ERC-7529.git
cd Testbed-ERC-7529
