Quick Start
EthPM is an Ethereum package manifest containing data types for contracts, deployments, and source code using EIP-2678. The library validates and serializes contract related data and provides JSON schemas.
Dependencies
- python3 version 3.9 to 3.12.
Installation
via pip
You can install the latest release via pip:
pip install ethpm-types
via setuptools
You can clone the repository and use setuptools for the most up-to-date version:
git clone https://github.com/ApeWorX/ethpm-types.git
cd ethpm-types
python3 setup.py install
Quick Usage
Starting with a dictionary of attribute data, such as a contract instance, you can build an EthPM typed object.
from ethpm_types import ContractInstance
contract = ContractInstance(contractType="ContractClassName", address="0x123...")
print(contract.contract_type)
Contract Type
Perhaps the most common artifact type from ethmp_types is ContractType.
ContractType represents components of a compiled contract, such as the .abi or the .runtime_bytecode.
from ethpm_types import ContractType
contract = ContractType(abi=[], runtimeBytecode="0x...")
For convenience, you can also initialize a ContractType using the .from_signature() classmethod:
from ethpm_types.abi import MethodABI, EventABI
MethodABI.from_signature("function_name(uint256 arg1)")
# => MethodABI(type='function', name='function_name', inputs=[...], ...)
EventABI.from_signature("Transfer(address indexed from, address indexed to, uint256 value)")
# => EventABI(type='event', name='Transfer', inputs=[...], ...)
ABI JSON
To easily acquire the ABI JSON for a ContractType artifact, .model_dump_json() the .abi property:
from ethpm_types import ContractType
contract_type = ContractType(abi=[], runtimeBytecode="0x...")
# Use the ABI in other application requiring ABI JSON.
abi = contract_type.abi.model_dump_json()
