Blockchain Development Programming Tutorials, Guides & Best Practices

• Hardhat will compile your contract and generate the necessary artifacts in the artifacts directory.

To deploy the ERC-20 token contract, you need to write a deployment script.

• Value Types:

- bool: true or false

• Choose data structures that minimize gas consumption. For example, mappings are generally more gas-efficient than arrays for storing large datasets.
• Example: Use a mapping instead of an array for storing user balances.

5. Avoid Unnecessary Computations

A smart contract is a self-executing contract with the terms of the agreement directly written into code. It runs on the Ethereum blockchain and automatically enforces the terms of the contract. Once deployed, it operates independently without the need for a central authority or intermediary, making transactions transparent, secure, and immutable.
