JEP SDK for JavaScript

JavaScript/TypeScript SDK for the JEP (Judgment Event Protocol). Generate, sign, and verify JEP Receipts for agent-to-agent transactions.

Installation

npm install @jep-eth/sdk

Quick Start

import { createReceipt, signReceipt, verifyReceiptOffChain } from '@jep-eth/sdk';

// 1. Create a receipt
const receipt = createReceipt({
  actor: '0x1234567890123456789012345678901234567890',
  decisionHash: '0xabcdef1234567890',
  authorityScope: 'erc-8183'
});

// 2. Sign it (using Ed25519 private key)
const signedReceipt = await signReceipt(receipt, privateKey);

// 3. Verify it
const result = await verifyReceiptOffChain(signedReceipt, publicKey);
console.log(result.isValid); // true or false
