Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

nexusgenesis-chain-adapters

NexusGenesis cross-chain adapters — one PQC root identity derives addresses on every supported chain. Private keys never leave the agent/browser.

| Chain | Crate | Key type | Address | |-------|-------|----------|---------| | NexusGenesis | nexusgenesis-agent-keys | Dilithium2 (PQC) | ng1... | | Ethereum | nexusgenesis-chain-eth | secp256k1 | 0x... (EIP-55) | | Solana | nexusgenesis-chain-sol | ed25519 | base58 |

Install

npm install nexusgenesis-chain-adapters

Usage

import { deriveChainAddresses, deriveAgentFingerprint } from 'nexusgenesis-chain-adapters';

// One PQC root identity → addresses on all chains:
const addrs = deriveChainAddresses(pqcPublicKey, pqcPrivateKey);
// { nexus: 'ng1...', eth: '0x...', sol: '6PT...' }

const fingerprint = deriveAgentFingerprint(pqcPublicKey); // stable sha256

API

  • deriveChainAddresses(pqcPublicKey, pqcPrivateKey) → { nexus, eth, sol }
  • deriveChainAddress(chain, pqcPublicKey, pqcPrivateKey) → single-chain address
  • deriveAgentFingerprint(pqcPublicKey) → stable sha256 agent fingerprint

Re-exports the full ETH / SOL adapters (deriveEthWallet, signEth, verifyEth, deriveSolWallet, signSol, verifySol, …).

Demo

See examples/demo-cross-chain.mjs for a runnable end-to-end demo (PQC root → three-chain addresses → coordination signature → ETH message signature → human takeover).
