Cairo Starknet Types

Overview

Explain the core Starknet types and when to use them instead of raw felt values.

Quick Use

• Read references/starknet-types.md before answering.
• Use explicit type conversions when needed (try_from, into, or constructors).
• Mention range constraints for addresses and hashes.

Response Checklist

• Use ContractAddress for any contract address parameter or storage.
• Use StorageAddress and StorageBaseAddress for storage slot computations.
• Use ClassHash for class identifiers and EthAddress for L1 addresses.
• Use BlockInfo and TxInfo for environment context.

Example Requests

• "How do I convert a felt into a ContractAddress?"
• "What is ClassHash used for?"
• "What is the difference between StorageAddress and StorageBaseAddress?"
