Event ticketing entirely decentralized.
The problem STARS solves
Stars gives organizers and attendees a safer, simpler, and more social way to run events. Organizers get instant, trustless payouts, transparent primary and secondary sales, private or allowlisted drops, and portable audience data, without platform fees or gatekeeping. Attendees get verifiable, unfakeable tickets that double as proof of participation, easy peer-to-peer resale, and a persistent social record that plugs into Farcaster for discovery and reputation. In practice, this means an indie venue can sell low-fee tickets and curb fraud, a conference track can verify session attendance for credentials, a DAO meetup can gate entry via on-chain lists, and any community can turn attendance into visible social capital, all with clearer ownership, lower costs, and fewer operational headaches.
Challenges we ran into
The hardest issues were around identity, metadata, and fraud. Farcaster auth inside a Mini App initially broke in mobile browsers due to mismatched redirect URIs and session handoff; We fixed this by introducing a short-lived OAuth bridge, strict state/nonce checks, and a single source of truth for the callback domain. On-chain, early check-ins were replayable if a ticket changed owners mid-flow; We refactored EventBook.sol around a per-ticket state machine (Minted → Listed → CheckedIn), added nonces and EIP-712 signatures for check-in, and made post-check-in tokens non-transferable. Dynamic metadata lag from IPFS caused stale badges; We switched to eager pinning with a placeholder JSON, then emitted a URI update event that the client listens to, with Redis caching and exponential backoff to stay within Neynar rate limits for social data. Together these changes eliminated double attendance, stabilized social login, and made metadata updates feel instant.

What is your product’s unique value proposition?
Stars turns event tickets into on-chain social identity: every ticket is an ERC-721 collectible on Base that doubles as verifiable proof of attendance, plugs directly into Farcaster for social discovery, and trades peer-to-peer with zero platform fees. Our alpha demonstrates this by shipping audited smart contracts (EventBook.sol and Ticket.sol) for minting and check-ins, a live Base deployment with low gas, Farcaster login and activity feeds, and embedded gamification (badges and leaderboards) that convert attendance into visible reputation and community status.
Who is your target customer?
Our initial focus is web3-native event organizers and communities Farcaster clubs, hacker houses, meetups, indie music collectives, conference tracks, and DAO-adjacent gatherings, plus their attendees who already hold crypto wallets and value public on-chain reputation. We validated this audience through Farcaster-first onboarding in the alpha, user tests of ticket mint/check-in flows, and organizer feedback highlighting zero fees, instant payouts, and the social lift from in-feed event visibility.
Who are your closest competitors and how are you different?
Centralized ticketing platforms like Ticketmaster (https://www.ticketmaster.com), Eventbrite (https://www.eventbrite.com), and DICE (https://dice.fm) excel at distribution but keep fees high, control data, and lack portable proof of participation. Web3 challengers like POAP (https://poap.xyz) and On Open(https://onopen.xyz/) provide on-chain credentials or infrastructure but are not Farcaster-native social surfaces. Stars is different by being Base-native with zero platform fees, Farcaster-integrated discovery and identity, on-chain P2P resale enforced by smart contracts, and built-in gamification that turns attendance history into social capital and reputation across ecosystems.
What is your distribution strategy and why?
We will grow Farcaster-first with community-driven distribution: partner with creators and venues to list events, surface them in-feed via Frames/Mini Apps, and reward sharing and referrals on-chain. This is reinforced by Base ecosystem co-marketing, targeted seeding of marquee community events, and developer tooling for easy listings. This approach fits our audience, crypto-forward organizers and attendees already active on Farcaster, while our zero-fee economics and instant payouts create a strong organizer pull that compounds through word-of-mouth within tightly knit communities.
