For Event Managers

Turn your event into a marketplace of vouchers

The best networking happens when people trade real value, not just business cards. barter.game lets your attendees mint personal currencies — “1 intro to my investor”, “1 portfolio review”, “1 lunch conversation” — and trade them on the spot.

Why add a voucher marketplace?

  • Attendees leave with concrete value, not just LinkedIn connections.
  • Icebreaker built in. “What can you offer? What do you need?” becomes the opening line.
  • No cash required. Mutual credit means nobody needs to pre-fund anything. Issuers go negative; holders go positive. The math balances.
  • Federation means no vendor lock-in. You run a bank for the event; attendees can keep using it afterward, or move to their own.

How it works at an event

  1. You deploy a bank (or we do it for you). It takes 10 minutes. See the self-hoster guide.
  2. Attendees open your bank’s web UI (<your-bank-url>/ui) and register with a handle and password. They now have a wallet.
  3. They mint vouchers — whatever they can deliver. “1 design review.” “1 investor intro.” “1 yoga class.”
  4. They trade. The protocol handles the cryptography. Attendees just scan a QR code or paste an invite string, then place a signed order — the web app coordinates the rest.
  5. Banks settle on their own. Once both sides have signed, balances update. The issuer now owes the holder a deliverable.

What your attendees see

  1. Open the bank’s web UI — https://your-event.example/event-bank/ui — and register with a handle and password. The key is generated and encrypted right in the browser.
  2. Mint a voucher — “1 portfolio review”, up to 5 of them.
  3. Share the QR code. Anyone who scans it sees the voucher and can propose a trade.
  4. Place an order — give 1 “portfolio review”, get 1 of theirs. The app creates the ledger records and clears the orders; the banks settle on their own.
  5. Watch the balances land in the wallet.

That’s the whole flow — the web UI ships with every bank today, and attendees never touch a terminal.

The day after

Attendees leave holding signed vouchers. They can redeem them later — a coffee meetup next week, a design review over Zoom. The voucher outlives the event. Your event becomes the origin of ongoing professional relationships, not just a one-day blur.
