Solidity Programming Tutorials, Guides & Best Practices

• Interact with your contract:

     const MyToken = await ethers.getContractAt("MyToken", "YOUR_DEPLOYED_CONTRACT_ADDRESS");
     await MyToken.mint("0xRecipientAddress", ethers.utils.parseUnits("1000", 18));

function multiply(uint a, uint b) public pure returns (uint) {
    uint result;
    assembly {
        result := mul(a, b)
    }
    return result;
}

• Use memory over storage for temporary variables.

2. Use view and pure Functions

• Functions declared with view or pure keywords do not modify the blockchain state and therefore do not consume gas when called externally (only when called by other contracts).
• Example: Use view functions for read-only operations, such as retrieving data from a contract.

• Node.js: Used to install necessary packages and tools.
• Remix IDE: An online integrated development environment for writing, testing, and deploying smart contracts.
• MetaMask: A browser extension that acts as a wallet and allows you to interact with the Ethereum blockchain.
