• Ganache: Personal blockchain for Ethereum development.

This Solidity cheatsheet covers the essential concepts and syntax needed to start writing and optimizing smart contracts. As you develop more complex contracts, always consider security, gas efficiency, and best practices to ensure your contracts are robust and cost-effective.

• 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.
