@epochcore/identity-sdk

World's First Universal Infrastructure Identity SDK

Generate Ed25519 cryptographic identities for workers, databases, storage buckets, durable objects, and daemons. Goes beyond ERC-8004 (agents only) to provide identity for your entire infrastructure.

Features

• Ed25519 Keypairs - Industry-standard elliptic curve cryptography
• secp256k1 Wallets - Ethereum/Base compatible wallet derivation
• DID Format - did:epochcore:<type>:<name>:<fingerprint>
• JWKS Support - OAuth2/OIDC integration ready
• Post-Quantum Ready - Prepared for NIST-5 algorithm upgrades

Installation

npm install @epochcore/identity-sdk

Quick Start

import { generateIdentity, deriveWallet, signPayload } from '@epochcore/identity-sdk';

// Generate identity for a Cloudflare Worker
const { identity, privateKey } = await generateIdentity('worker', 'my-api-worker');

console.log(identity.did);
// did:epochcore:worker:my-api-worker:a1b2c3d4e5f6g7h8

// Derive Web3 wallet for on-chain operations
const wallet = deriveWallet(privateKey, identity.did);
console.log(wallet.address);
// 0x1234...abcd

// Sign a payload
const signed = await signPayload('{"action":"deploy"}', privateKey);

Identity Types

| Type | Use Case | |------|----------| | worker | Cloudflare Workers, Lambda functions | | database | D1, Postgres, SQLite databases | | storage | R2 buckets, S3, blob storage | | durable_object | Stateful edge objects | | daemon | Local background processes |

JWKS Endpoint

Generate a JWKS for your infrastructure identities:

import { generateJWKS } from '@epochcore/identity-sdk';

const jwks = generateJWKS([identity1.publicKey, identity2.publicKey]);
// Serve at /.well-known/jwks.json

Funded on Base Mainnet

Our production ecosystem has 130 identities with 44 wallets funded on Base L2.
