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.” Vouchers can carry icons and artwork, so they look like something worth trading.
  4. They post them. Every attendee follows the event bank by default, and the bank rebroadcasts every post it accepts — so one post puts a voucher in front of the whole event. The marketplace is automatic; no setup, no announcements channel.
  5. They trade. Attendees browse the Home feed and hit “Trade for this,” or scan a QR code / paste an invite string, then place a signed order — the web app coordinates the rest.
  6. Banks settle on their own. Once both sides have signed, balances update. The issuer now owes the holder a deliverable.

Handing out swag? A cheque link lets an attendee claim a voucher just by opening a URL.

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 — and give it an icon if they like.
  3. Post it and browse the feed. A post about the voucher lands in every attendee’s Home feed (everyone follows the event bank by default, and the bank rebroadcasts accepted posts). Home shows a gallery of everyone else’s vouchers with a “Trade for this” button that preloads the swap.
  4. Share the QR code. Anyone who scans it sees the voucher and can propose a trade.
  5. 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.
  6. 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.
