Smartcontract Caller

The Smartcontract Caller is a standalone node-webkit app, that enables users to call a contract method on an EVM-compatible blockchain by uploading input configuration files in JSON format.

Disclaimer : This is a badly and quickly written project, with uneccesary machinery, and a very client-heavy distribution.

Supported Blockchains:

• Binance Smart Chain - Mainnet
• Binance Smart Chain - Testnet

Instructions

1. Download the latest release. Choose version accordingly.
2. Unzip the downloaded app folder.
3. Download the configuration template files (Release > config-template.zip).
4. Edit the configuration templates. References for parameter format are given below.
5. Launch the .exe in the app folder.
6. Upload the edited configuration files in the launched app.
7. Execute and wait for your call result or transaction hash.

Configuration files format

All files should be in JSON format.

Secrets

PRIVATE_KEY : the private key that you wish to sign transactions with.

This parameter is of type string.

• METHOD_TYPE: Either read or write . Read methods do not alter contract state (don't need to sign anything or pay fee) whereas write methods do.
• METHOD_PARAMETERS: All the parameters that are needed to call the fucntion. They should be placed in an array. All parameters of solidity type address should be a placed in the array as a string, all number types should be written as int or float and be in ethers (the program will multiply by 10^18 to convert it in wei).
  e.g. for the method transfer(address,uint256) parameters could be ["0x437C2AD9E62e3f9Ef8d76Dd6Bb1A5deF35B37Cc7", 123].

Except for METHOD_PARAMETERS which is an Array, all other parameters are of type string.
