Overview

The Problem

Event check-ins are easy to fake. Bots and multi-wallet farmers drain rewards meant for real attendees, organizers can't verify who actually showed up, and builders have no portable record of the events and communities they've been part of.

The Solution

Signal attaches to any Luma or Eventbrite event. Attendees scan a QR code, verify they're human with World ID, and check in on-chain. Every check-in becomes a permanent Proof of Presence and builds their Signal Score.

Features

Proof of Presence (POAP)

Check in to an event and get an on-chain proof that you were really there. Each check-in is verified, so one person can only claim once.

  • Works with Luma & Eventbrite

    Organizers attach Signal to an event they already run on Luma or Eventbrite. One transaction creates the check-in QR code, with no need to rebuild the event somewhere new.

  • Scan & verify with World ID

    Attendees scan the QR code and confirm they're human with World ID: one human, one check-in. Bots and people with many wallets can't farm rewards.

  • Multi-chain

    Check in and claim your proof on Solana, Avalanche, Base, Polygon, or Ethereum, wherever the community lives.

  • Signal Score & Builder Passport

    Every check-in raises your Signal Score and adds to your Builder Passport, a portable on-chain record of the events and communities you've been part of.
