ape-utils 0.0.3

Utility plugin to expose some of the Ape's awesome features to CLI

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

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:

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"
