That one rule is what makes buying from a stranger safe. Here is every step, from either side of the sale.
Five steps. You only act in two of them.
Only the ticket price sits in escrow. The fees are charged separately at checkout.
You only pay once you have picked a listing.
Only the ticket price sits in escrow. The fees are charged separately at checkout.
The seller cannot touch it before the show is over.
Where the show is decides how you pay. Both run on test money for now.
Pay in rupiah from any banking or e-wallet app. Xendit, a licensed payment company, holds the money until the show; each step is recorded publicly on Arbitrum. Service fee 5%, at least Rp25,000. For now QRIS runs in Xendit's test mode, so no real money moves.
Pay from your own wallet. You sign twice, Lummy pays the gas, and the USDC is locked in the escrow contract on Arbitrum. No service fee while it runs on testnet: test USDC on Arbitrum Sepolia, not real money. The claim window after the show is 10 minutes on this testnet demo, 48 hours in production.
Each case has one path, and each path names what decides it. Nothing ends in "contact support".
Claim before the show. Our record of whether you opened the handover documents decides it, so there is nothing for you to prove.
File within 48 hours with a photo taken there. The time, the venue and the code on screen all have to match, so someone who walked in cannot claim. A person reviews it and decides.
Still got in on a lower tier? You get the difference back, not the full price.
Refunded automatically, service fee included. Nobody files anything and the seller is not penalised.
Your ticket stays valid and the money stays held until the new date. If the new date does not work for you, take the refund.
That is not a refund, because the ticket works. Relist it before the show and get your money back from the next buyer.
You do nothing. 48 hours after the show, the money is released to the seller and the sale is closed.
What protects both sides of every sale.
The server reads each barcode and checks how the PDF was made and changed. A suspicious file goes to a person; the machine never decides alone. With a real PDF, Claude (Anthropic's AI) reads its text after names and numbers are taken out, and fills in the show and tier for you to check.
A barcode that has been sold on Lummy before is blocked outright. That check is exact, not a guess.
No listing can ask more than one and a half times face value, or less than half of it.
Whether money is held, released or refunded is recorded publicly on Arbitrum. You can check it yourself.
