• Write your smart contract in Remix IDE, regularly checking the gas estimates.
• Deploy the contract on a test network using Truffle or Hardhat.
• Use Solidity Coverage to generate a gas report and identify optimization opportunities.

Writing gas-efficient smart contracts is a balance between functionality, security, and cost. Here are some best practices to follow:

• Run truffle init in your terminal to create a new Truffle project.
• Place your smart contract code in the contracts/ directory.

• Run truffle compile to compile the smart contract. This will generate the necessary ABI (Application Binary Interface) and bytecode.
