56-56: Consider adding a compile-time verification.The
DEFAULT_LEGACY_ERC20_CLASS_HASHis used in conjunction withDEFAULT_LEGACY_ERC20_CLASSlazy_static. Consider adding a test similar to the controller_class_hash test to verify at compile-time that the constant matches the actual contract hash.Example test:
#[test] fn erc20_class_hash() { let hash = DEFAULT_LEGACY_ERC20_CLASS.class_hash().unwrap(); assert_eq!(hash, DEFAULT_LEGACY_ERC20_CLASS_HASH); }Also applies to: 89-89

27-49: Ohayo sensei! Documentation changes look clean and precise!
The simplified comments now focus on the essential information (keccak function calls) without redundant hexadecimal representations. This makes the code more maintainable while preserving the important context.
56-56: Verify consistency with ERC20 contract implementation.
The class hash has been updated as intended, but let's verify it matches the compiled ERC20 contract.
✅ Verification successful
Ohayo sensei! After analyzing the codebase, I can now provide a final response about the ERC20 class hash update.
ERC20 class hash update is correctly implemented and verified by tests
The new class hash is used consistently throughout the codebase and is properly verified in the executor tests. The tests specifically verify:
- Contract deployment using this class hash
- Storage initialization with correct values
- Class hash registration in state updates
The test file executor.rs contains comprehensive verification that:
- The contract deploys successfully with this class hash
- The deployed contract's storage is properly initialized
- The class hash is correctly registered in state updates
🏁 Scripts executed
The following scripts were executed for the analysis:
