Moments by MatCrypt

Pics or it didn't happen. Proof or it didn't count.

Scan the QR at the event. Get a numbered, one-of-a-kind card that proves you were actually there. Drop it on your Story. Nobody can fake it, because every card is cryptographically signed.

How it works

From the door to the Story in under 30 seconds.

  1. 1

    Host creates a drop

    Describe the event and its vibe. Claude designs a card that feels like the night: headline, colours, emoji. Optional: limit it to the first 50.

  2. 2

    QR goes up at the venue

    Only people physically there can scan it. No ticket integration, no app download.

  3. 3

    Attendees claim with their @handle

    Each card gets a number, a personal caption written by Claude, and a signed proof anyone can verify.

  4. 4

    They post it. Their friends see it.

    One tap shares a Story-sized card. Every post is an ad for the next event, so it markets itself.

For event hosts

Your crowd becomes your marketing

  • Free reach

    Every attendee who posts their card puts your event in front of their followers.

  • Built-in FOMO

    Numbered, limited cards (“#12 of 50”) give people a reason to show up early and post.

  • Know your crowd

    See who actually came, in real time, with handles you can reach next time.

  • Can’t be faked

    A card only comes from scanning the QR at the venue, and every one is signed.

Concerts, college fests, club nights, run clubs, pop-ups, sneaker drops.

Built with Claude

Every card is one of one

Moments uses Claude by Anthropic as its creative engine, so a hundred people at the same event still get a card that feels like theirs.

Designs every drop

A host types “sunset techno on a rooftop, everyone in black.” Claude turns it into a card: headline, tagline, emoji and a colour palette that feels like the night.

Writes every caption

Each attendee gets their own one-liner, tuned to their number and how rare the drop is. No two cards read the same.

Coming next

Year-end recaps of everywhere you’ve been, moderation for new drops, and plain-language explanations of anything the wallet asks you to sign.

The tech underneath

Built on MatCrypt Wallet

Before Moments, we built a multi-chain wallet. The same key management and signing now powers every card: each claim is signed with standard Ethereum message signing (EIP-191), so anyone can check a card is real without trusting our servers.

The wallet itself is a browser extension in active development, with send and receive across:

  • Bitcoin
  • Lightning
  • Ethereum
  • Polygon
  • Arbitrum
  • BNB Chain
  • Cosmos
  • Akash
  • Secret Network

Plus BTCPay Server for Bitcoin payments and Arweave for permanent storage.
