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: EAS attestation verification is not yet implemented. This package currently provides Ethereum-based signing and verification (ES256K). EAS integration is planned for a future release.

Features

  • Sign and verify ProofPack envelopes using Ethereum keys (ES256K)
  • Ethereum curve and hasher support
  • EAS (Ethereum Attestation Service) integration coming soon: Attestation verification is not yet implemented, but is planned for a future release.
  • 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

Roadmap

  • Attestation checking via Evoq.Ethereum library.
