Description:
apeutils 0.0.6
Ape_utils
Quick Start
Ape Utils is a CLI tool designed to interact with Ethereum smart contracts, specifically focusing on calling view functions. The tool allows you to call a view function from a given function signature and address directly from the command line.
Demo
Features
Call View Functions: Invoke view functions on Ethereum smart contracts using their function signature and address.
Flexible Input: Provide function signature, contract address, and arguments through the command line.
Dependencies
python3 version 3.9 up to 3.12.
Installation
via pip
You can install the latest release via pip:
pip install ape_utils
Build locally
You can clone the repository and use pip for the most up-to-date version:
git clone https://github.com/Aviksaikat/ape_utils.git
cd ape_utils
pip install -e .
Quick Usage
Once installed, you can use the ape_utils command to call view functions on Ethereum smart contracts. Here is how you can use it:
ape_utils call --function-sig "function_signature" --address "contract_address" --args [argument] --network [ecosystem-name][:[network-name][:[provider-name]]]
Examples
Calling a view function with single parameter
To call a view function with the signature call_this_view_function(uint256)(string) on a contract at address 0x80E097a70cacA11EB71B6401FB12D48A1A61Ef54 with an argument 6147190, you can use:
# function which takes a single input parameter
ape_utils call --function-sig "call_this_view_function(uint256)(string)" --address "0x80E097a70cacA11EB71B6401FB12D48A1A61Ef54" --args '[6147190]' --network :sepolia:infura
# or
ape utils call -s "call_this_view_function(uint256)(string)" -a "0x80E097a70cacA11EB71B6401FB12D48A1A61Ef54" -ag '[6147190]' --network :sepolia:infura
Calling a view function with multiple parameter
# function which takes multiple input parameters
ape_utils call --function-sig 'couple_param_function(uint256,string)(string)' --address '0x894A02d4574318a9da4EEc7884a7D0c095E65507' --args "[6147190,'string']" --network :sepolia
# function with 3 input parameters
ape_utils call --function-sig 'multiple_param_function(uint256,string,address)(string)' --address '0x894A02d4574318a9da4EEc7884a7D0c095E65507' --args "[6147190,'string', '0x894A02d4574318a9da4EEc7884a7D0c095E65507']" --network :sepolia
Use as ape plugin
ape utils --help
ape utils call --function-sig "call_this_view_function(uint256)(string)" --address "0x80E097a70cacA11EB71B6401FB12D48A1A61Ef54" --args '[6147190]' --network :sepolia:infura
ABI encode the given function
ape_utils encode --signature 'call_this_view_function(uint256 arg1, string addr)' 1234 '0xdeadbeef'
ABI Decode input data
ape_utils decode --signature 'call_this_view_function(uint256 arg1, string addr)' '0x00000000000000000000000000000000000000000000000000000000000004d20000000000000000000000000000000000000000000000000000000000000040000000000000000000000000000000000000000000000000000000000000000a3078646561646265656600000000000000000000000000000000000000000000'
Encode the given function with function selector
ape_utils encode --signature "call_this_view_function(uint256 arg1)" 1234
Decode the given function with function selector
ape_utils decode --signature "call_this_view_function(uint256 arg1)" "0x1e4f420d00000000000000000000000000000000000000000000000000000000000004d2"
Don't want beautiful print statements ?
You can now pass the --raw flag to each option to print the output data only
ape_utils encode --signature 'isLastFloor(uint256 arg1)' 1234 --raw
Read storage slots of a contract
ape utils read --address "0xDbB18e367E4A2A36A9F2AF7af8b3c743938deCF2" --slot 1 --network :sepolia
