Package Exports

@zipwire/proofpack-ethereum
@zipwire/proofpack-ethereum/src/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@zipwire/proofpack-ethereum) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

@zipwire/proofpack-ethereum

Ethereum integration for ProofPack with ES256K signatures, EAS attestations, and multi-network blockchain verification.

Quick Start

npm install @zipwire/proofpack-ethereum

import { 
    EasAttestationVerifierFactory, 
    ES256KVerifier,
    ES256KJwsSigner 
} from '@zipwire/proofpack-ethereum';

// Verify EAS attestations
const networks = {
    'base-sepolia': {
        rpcUrl: 'https://api.developer.coinbase.com/rpc/v1/base-sepolia/YOUR_API_KEY',
        easContractAddress: '0x4200000000000000000000000000000000000021'
    }
};

const verifierFactory = EasAttestationVerifierFactory.fromConfig(networks);
const result = await verifierFactory.verifyAsync(attestation, merkleRoot);

// Verify ES256K signatures
const verifier = new ES256KVerifier('0x1234567890123456789012345678901234567890');
const isValid = await verifier.verifyAsync(jwsToken, messageHash);

// Sign with ES256K
const signer = new ES256KJwsSigner('0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef');
const signature = await signer.sign(payload);
