AddressType

ChecksumAddress
✓ from eth_pydantic_types import ChecksumAddress

Define a Pydantic model with Ethereum-specific types for validation.

from pydantic import BaseModel from eth_pydantic_types import AddressType, HexStr, ChecksumAddress class Contract(BaseModel): address: AddressType bytecode: HexStr # Example usage (for testing) contract = Contract( address='0xdAC17F958D2ee523a2206206994597C13D831ec7', bytecode='0x608060405260043610...' ) print(contract.model_dump())

Known issues
breakingVersion 0.2.0 changed the import base from `eth_pydantic_types.types` to `eth_pydantic_types`. Old imports like `from eth_pydantic_types.types import AddressType` will break.
fix
Update imports: `from eth_pydantic_types import AddressType`.
affects: >=0.2.0
gotchaThe library does not validate that a hex string has an even number of characters (except for AddressType which checks length). Use `HexStr` for arbitrary-length hex but ensure your application logic validates length.
fix
Add custom validators for hex length if needed.
affects: >=0.1.0

ImportError: cannot import name 'AddressType' from 'eth_pydantic_types'
