evm-decoder 0.1.5

A package for decoding and analyzing EVM transactions and logs

EVM Decoder

EVM Decoder is a Python package for decoding and analyzing Ethereum Virtual Machine (EVM) transactions and logs. It provides tools to help developers and researchers understand and work with EVM-based blockchain data.

Features

• Decode EVM transaction input data
• Decode EVM event logs
• Analyze balance changes in transactions
• Support for custom ABI and fixed types
• Retrieve chain information for various EVM-compatible networks

Installation

You can install the EVM Decoder package using pip:

bash
pip install evm-decoder

Usage

Here's a quick example of how to use EVM Decoder:

python from evm_decoder import DecoderManager, AnalyzerManager Initialize managers decoder_manager = DecoderManager() analyzer_manager = AnalyzerManager() Example transaction data transaction_data = { 'input': '0x23b872dd000000000000000000000000...', 'from': '0xb8faa80fe04a4afd30c89f40e4fcdc6dafb274d9', 'to': '0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48', 'value': '0', 'chain_id': 1, 'logs': [...] } Decode the transaction decode_result = decoder_manager.decode(transaction_data) print("Transaction decode result:", decode_result) Analyze the transaction analysis_result = analyzer_manager.analyze_transaction(transaction_data, {}) print("Transaction analysis result:", analysis_result)

Configuration

EVM Decoder uses a configuration file to set up decoders. You can customize this file to add support for specific contracts or event types. The default configuration file is located at evm_decoder/config/decoder_config.json.
