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 🙏

xnt — Neptune Privacy Core SDK (nodejs and rust)

License Coverage Status

xnt-core is the reference implementation for xnt (Neptune Privacy) — a privacy-focused decentralized digital cash protocol derived from Neptune Cash.

The XNT SDK provides the core tools needed to build applications that interact with the network without custody.

This includes offline transaction signing, so private keys never leave the client or trusted environment.

Why this matters: Most privacy apps today still depend on custodial backends, trusted relayers, or opaque infrastructure.

The XNT SDK enables applications where users remain in full control, end-to-end.

The SDK is open source and intended as foundational infrastructure for:

  • wallet developers
  • application builders
  • tooling teams
  • anyone building on private execution

Builders, the next phase is in your hands.

Address Types

The SDK supports two address families, both derived from the same wallet seed:

Generation (long address)

  • Rust: WalletEntropy::derive_spending_key(index)
  • Node.js (NAPI): wallet.deriveKey(index)
  • C FFI: xnt_wallet_derive_key(wallet, index)

dCTIDH-512 (short address)

  • Rust: WalletEntropy::derive_dctidh_spending_key(index)
  • Node.js (NAPI): wallet.derivedCTIDHKey(index)
  • C FFI: xnt_wallet_derive_dctidh_key(wallet, index)

Both support subaddresses with payment IDs for deposit tracking.

We’ll continue improving the SDK and releasing updates as the ecosystem grows. If you’re building privacy preserving applications and care about non-custodial design, this is for you!
