EIP6492-Signature-Verifier

Overview

The erc6492_signature_verifier library is a Python package designed to verify Ethereum signatures in compliance with EIP-6492. It supports both smart contract and externally owned account (EOA) signatures, automatically selecting the appropriate verification method based on the length of the signature. This library simplifies the process of signature verification for Ethereum-based applications.

Features

• Smart Contract Signature Verification: Validates signatures associated with Ethereum smart contracts.
• Externally Owned Account (EOA) Signature Verification: Verifies signatures from externally owned accounts.
• Automatic Method Selection: Determines the appropriate verification method based on the signature length.

Installation

You can install the erc6492_signature_verifier library from PyPI using pip:

pip install erc6492_signature_verifier

Usage

Here’s a quick guide on how to use the SignatureVerifier class:

Example

from erc6492_signature_verifier import SignatureVerifier

# Initialize the verifier with your Web3 provider URL
verifier = SignatureVerifier("YOUR_WEB3_PROVIDER_URL")

# Example data
signature = "0x..."  # Replace with the actual signature
message = "Hello, world!"
signer = "0x..."  # Replace with the actual signer's Ethereum address

# Verify the signature
is_valid = verifier.verify_signature(signature, message, signer)
print(f"Signature valid: {is_valid}")

Method Descriptions

• SignatureVerifier(web3_provider: str): Initializes the verifier with the specified Web3 provider URL.
• verify_signature(signature: str, message: str, signer: str) -> bool: Verifies the given signature. The method automatically selects whether to use smart contract or EOA verification based on the signature length.
