• ERC20/721 Tokens: Standards for implementing tokens.

• ERC20: Standard interface for fungible tokens.

1. Minimize Storage Writes

• Writing data to the blockchain is one of the most expensive operations. Whenever possible, minimize storage writes or combine them into a single operation.
• Example: Instead of updating multiple state variables individually, group them into a struct and update the struct in a single operation.

Steps to Deploy:

• Switch to the "Deploy & Run Transactions" tab.
• Select "Injected Web3" as the environment to connect to MetaMask.
• Choose a test network like Ropsten or Kovan in MetaMask.
• Click "Deploy" and confirm the transaction in MetaMask.
