The critical methods within the ACCTBridge class include:

• __init__: Initializes the ACCTBridge object, establishing an RPC bridge for interaction and retrieves the private key and account address.

• check_priv_key & get_address_from_private_key: Manages operations related to the private key and converts it into an Ethereum address.

• build_txn & get_txn_info: Allows the user to build a transaction, accounting for multiple variables.

• check_sum & try_check_sum: Manages the conversion of the address to a checksum address.

• get_transaction_count: Fetches the transaction count of the Ethereum account.

• sign_transaction & send_transaction: Handles the signing and sending of transactions.

• estimate_gas: Estimates the gas fee for Ethereum transactions.

The module employs a rate limiting manager to manage the frequency of requests, preventing the exceeding of API rate limits.

Module - abstract_abis.py

Part of the abstract_blockchain package, the abstract_abis.py module is a critical component intended to streamline interactions with Ethereum smart contracts, providing a Pythonic interface to their Application Binary Interfaces (ABIs). The core of this module is the ABIBridge class, which offers an encompassing interface for managing Ethereum contract ABIs.

Just like the abstract_accounts.py module, abstract_abis.py performs various tasks in collaboration with other modules, principally abstract_rpcs.py and abstract_apis.py.

It houses several methods responsible for:

• Validating Ethereum addresses
• Creating ABI bridges
• Enumerating contract functions
• Accessing read-only functions from contract ABIs
• Invoking contract functions
• Acquiring and categorizing RPC parameters that are crucial for interaction with the blockchain
• Managing rate limiting for API requests

The ABIBridge class also emphasizes contracts' functions, offering tools to list all functions, obtain necessary input details, and invoke functions smoothly. It also provides mechanisms to create functions ready to be executed in future operations.

A default_rpc() function is also included, providing a default RPC configuration used when an instance of ABIBridge is created. This function underlines how to utilize the ABIBridge class for tasks like interacting with Ethereum contracts, managing user interaction, retrieving read-only functions, obtaining required input details, and invoking contract functions.

Module - abstract_api_gui.py

Part of the abstract_blockchain package, abstract_api_gui.py is a module that builds a Graphical User Interface (GUI) to simplify interactions with APIs. This module utilises PySimpleGUI for creating the GUI, and abstract_utilities.list_utils for utility functions. The primary features of this module include:

• Declaring hard-coded API descriptions through apiCallDesc
• Defining options for API actions using options
• Streamlining API parameters with inputs

Additionally, it introduces several functions to generate API GUI and manage user interactions:

1. get_revised_dict(): This function modifies a dictionary based on required keys.
2. generate_api_variables(): This function produces API variables based on user input.
3. generate_api_gui(api_desc): Generates the GUI layout with the given API description.
4. make_invisible_unless(window,values,visible_list,example): Manages UI elements' visibility based on user input.
5. choose_api_gui(): Renders the main GUI displaying available APIs, parameters, and execution results.

In the main application execution, choose_api_gui function gets called to display the user interface. As user actions are detected in the dropdown or interaction buttons, relevant changes are made in the GUI, providing a user-friendly environment for API interaction.

The abstract_apis.py Script

The abstract_apis.py script is a core component of the abstract-blockchain module. This script houses the APIBridge class which serves as the robust engine for API URL construction and execution, and efficient GUI management for RPC parameters.

Key Components

• APIBridge class: This primary class initializes with optional parameters, api_data, rpc, and address. To ensure smooth functionality and improve efficiency, the class imports from external modules namely, abstract_webtools and abstract_utilities.

Methods of the APIBridge class include:

• get_api_data_string: This method prepares the appropriate API data string based on the provided api_data_type and address.

• api_keys: An essential method that retrieves API keys from the environment settings contingent on the scanner in use.

• get_http_variants, get_api_variants: These methods lend a hand in navigating different versions of the API URL based on request requirements.

• try_api_url: As the name suggests, this method obtains the API request URL.

• get_try, get_request: Key in sending a request to the API URL with a focus on 'Rate-Limiting'.

• get_response: This method parses the JSON response from the API.

• check_sum, try_check_sum: Integral in ensuring the validity of an Ethereum address and converting it to a checksum address.

• safe_json_loads: A safety-oriented method that loads JSON data as a dictionary or a list.

Remember to study the functional activities of this module and understand its relevance in the larger abstract-blockchain module. Join us in the next section where we detail another integral part of the module, the abstract-api-gui.py script.

abstract_contract_console.py

The abstract_contract_console.py module within the abstract-blockchain package offers a Graphical User Interface(GUI). This GUI is ideal for users interested in engaging interactively with the Smart Contracts on the Ethereum Blockchain. At its core, it is designed to provide a user-friendly console for interacting with Ethereum Smart Contract functions.

The module imports required dependencies and presents helper functions to perform data conversions and error checks. This setup lays the foundation for an interface that allows users to input a contract address on the Ethereum Blockchain. Once the address is provided, the interface makes a connection with a network node that will process the desired transactions and fetch available contract functions.

All available functions are displayed in the GUI, which features input fields and buttons to facilitate interaction. The GUI shows the return value for functions having 'read' or 'pure' mutability; for transaction-triggering functions, the transaction hash is displayed.

Notably, this module also permits users to manually input their account details, vital for signing transactions when calling non-read-only functions. Determining the Endpoint URL to connect to an Ethereum node is made simple with the get_account_layout and determine_correct_rpc functions.

Operating within a GUI Event Loop, the interface maintains responsiveness and interactive capabilities. When a button associated with a contract function is clicked, input values are collected, the function is executed, and the output is displayed.

In summary, abstract_contract_console.py emulates a local Ethereum interaction console, simplifying users' interactions with the Ethereum Blockchain and providing an all-in-one abstraction service.

Furthermore, the module features an abstract_contract_console_main(). This function leverages various classes from the package for smart contract interaction and accepts an optional 'rpc_list' argument. If no argument is provided, it defaults to the RPC list from the RPCBridge class. To launch a new window titled 'New Blockchain Console,' it retrieves the RPC layout and values, constructs a final layout consisting of the account, ABI, and RPC layouts. The new_window_mgr object's while_basic() method responsibly handles the main application loop, managing events and rendering.
