Address Converter

A lightweight Python library for converting blockchain addresses between different formats, with initial support for EVM-compatible chains and other blockchain networks.

Features

• Convert addresses between different blockchain formats
• Support multiple encoding formats (Base58Check, Hex)
• Comprehensive address validation
• Minimal dependencies (only base58)
• Type hints support
• Thoroughly tested

Installation

pip install address-converter

Quick Start

from address_converter import evm_to_tron, tron_to_evm, get_address_type

# Convert EVM format to alternative format
evm_address = "0x123456789abcdef123456789abcdef123456789a"
alt_base58 = evm_to_tron(evm_address, output_format='base58')
alt_hex = evm_to_tron(evm_address, output_format='hex')

print(f"Base58 format: {alt_base58}")
print(f"Hex format: {alt_hex}")

# Convert from alternative format to EVM
alt_address = "TJCnKsPa7y5okkXvQAidZBzqx3QyQ6sxMW"
evm_result = tron_to_evm(alt_address, add_prefix=True)
print(f"EVM format: {evm_result}")

# Detect address type
address_type = get_address_type(evm_address)
print(f"Address type: {address_type}")  # 'evm'

API Reference

evm_to_tron(evm_address: str, output_format: str = 'base58') -> str

Convert an EVM address to alternative blockchain format.

• Parameters:
  • evm_address: EVM address (with or without '0x' prefix)
  • output_format: Output format, either 'base58' or 'hex'
• Returns: Address in specified format
• Raises: ValueError if address is invalid

tron_to_evm(tron_address: str, add_prefix: bool = True) -> str

Convert an address from alternative blockchain format to EVM format.

• Parameters:
  • tron_address: Address in Base58Check or Hex format
  • add_prefix: Whether to add '0x' prefix
• Returns: EVM address
• Raises: ValueError if address is invalid

get_address_type(address: str) -> Optional[str]

Detect address type.

• Parameters:
  • address: Address to detect
• Returns: Address type string ('evm', 'tron_base58', 'tron_hex') or None if invalid

Address Format Details

EVM Address

• 40 hexadecimal characters (excluding '0x' prefix)
• Case-insensitive
• Optional '0x' prefix

Alternative Address Formats

• Base58Check format: Specific prefix character, fixed length
• Hex format: Specific byte prefix, fixed length
