- Arithmetic Operations: Adding, subtracting, or multiplying integers consumes minimal gas (e.g., 3-5 gas units).
- Storage Operations: Writing data to the blockchain (e.g., updating a state variable) is expensive (e.g., 20,000 gas units).
- Function Calls: Calling a function, especially one that interacts with another contract, can significantly increase gas consumption.
Optimizing gas consumption in smart contracts can lead to substantial cost savings, especially for frequently executed contracts. Here are some strategies to consider:
