What Is Blockhash

Blockhash is a home for onchain works: ownership, access, tokens, community software, and the contracts behind them. Current projects are Slonks, Howdy, and Regular Punks.

Blockhash formally started in 2025, but the work under it has been shipping since 2024.

Who Started It

I'm Michael Hirsch. I've been writing software for over a decade, and most of that time I've spent co-founding things. The headlines: Facet, a DEX I built with Tom Lehman (co-founder of Genius) that did $400M+ in volume; Ethscriptions, an inscription primitive on Ethereum; Carve, an NFT launchpad; and Kickstart Crew, a startup studio I grew to a team of ten. Somewhere in the middle of all that I also built Taskful, a productivity app that hit #1 in the App Store. Blockhash is the current chapter.

There's a longer bio if you want the full story.

How Blockhash Works

Each project starts with a direction: ownership, access, tokens, or contracts becoming part of the interface.

Blockhash is set up around shipping. Build the thing, launch it, and let real use shape what it becomes next.

How It Works: Vibe-Coding

Every project under Blockhash is vibe-coded. Work moves in the order the idea needs, with AI as a force multiplier on top of everything I've shipped before. Change direction quickly, keep tests close to the implementation, and keep improving the work as it moves.

What We're Building

  • Slonks: the Slonks collection, $SLOP, and sealed Slop Packs.
  • Howdy: Token-gated chat for NFT and token communities.
  • Regular Punks: CryptoPunks as onchain robot dogs, with a real-ETH fight game in development.

Operating Mode

  • Independent onchain work
  • Launches over roadmaps
  • Contracts and interfaces designed together
  • Projects that can keep evolving after launch

Where to Find the Rest of It

Blockhash lives at blockhash.xyz (and also at blockha.sh because that domain was too good to pass up). Source code is on GitHub. The occasional thought gets posted on X. More projects are on the way.
