Zipwire.ProofPack.Ethereum

Ethereum integration for ProofPack: verifiable data exchange with EAS attestation support.

Overview

This package extends the core ProofPack library to support:

  • Ethereum L1 and L2 attestation verification (EAS)
  • ES256K JWS signing and verification
  • Utilities for working with Ethereum addresses and keys

Note: This package provides complete EAS attestation verification along with Ethereum-based signing and verification (ES256K). Supports Base Sepolia and other EAS-enabled networks.

Features

  • Sign and verify ProofPack envelopes using Ethereum keys (ES256K)
  • Ethereum curve and hasher support
  • EAS (Ethereum Attestation Service) integration: Complete attestation verification with factory pattern support for multiple networks
  • Designed for composability with the core ProofPack library

Installation

dotnet add package Zipwire.ProofPack.Ethereum

Usage Example

using Zipwire.ProofPack.Ethereum;

// Create a signer with your Ethereum private key
var signer = new ES256KJwsSigner(privateKey);

// Sign a ProofPack envelope (see core library for envelope creation)
var signed = await signer.SignAsync(header, payload);

// Verify a signed envelope
var verifier = new ES256KJwsVerifier(expectedSignerAddress);
var result = await verifier.VerifyAsync(signed);

Requirements

  • .NET Standard 2.1 or later
  • .NET 7.0 or later (for running tests)

Documentation

EAS Attestation Verification

This package provides comprehensive EAS attestation verification:

using Zipwire.ProofPack.Ethereum;

// Configure EAS networks
var networkConfig = new EasNetworkConfiguration(
    "Base Sepolia",
    "base-sepolia-provider", 
    "https://sepolia.base.org",
    loggerFactory);

// Create attestation verifier
var verifier = new EasAttestationVerifier(new[] { networkConfig });

// Use with AttestedMerkleExchangeReader
var verificationContext = AttestedMerkleExchangeVerificationContext.WithAttestationVerifierFactory(
    maxAge: TimeSpan.FromDays(30),
    jwsVerifiers: verifiers,
    signatureRequirement: JwsSignatureRequirement.All,
    hasValidNonce: nonce => Task.FromResult(true),
    attestationVerifierFactory: factory);

var reader = new AttestedMerkleExchangeReader();
var result = await reader.ReadAsync(jwsJson, verificationContext);
