Dapp Development Tutorials, Guides & Insights

• Basic understanding of Ethereum and blockchain concepts.
• Familiarity with APIs and programming in Node.js or any other language.

Before diving into code examples, it's important to understand the core differences between Etherscan and Infura.

To follow along with this tutorial, you’ll need:

• Node.js installed on your machine.
• A basic understanding of JavaScript and blockchain concepts.
• An Ethereum wallet with some test ETH (using testnets like Goerli or Ropsten is recommended for testing).
• An Infura Project ID to access the Ethereum network.

const updateIPFSHash = async () => {
  const ipfsHash = 'Your IPFS hash here';
  await contract.methods.setIPFSHash(ipfsHash).send({ from: account });
  const updatedIPFSHash = await contract.methods.getIPFSHash().call();
  console.log(updatedIPFSHash);
};

To deploy your smart contract to the Ethereum mainnet, you’ll need to configure Truffle to connect to an Ethereum node (e.g., Infura) and provide a wallet with Ether to pay for gas.
