説明

The problem Concert ticket resale in Indonesia runs through WhatsApp groups and X replies, with nobody in the middle. The buyer pays a stranger first, and when the ticket turns out fake or already used, the money is gone. At Coldplay's 2023 Jakarta show, police recorded 400 victims of ticket fraud and about Rp1.3 billion in losses.

What Lummy does Lummy is escrow for that resale: the seller gets paid only after the show. The buyer's money is held until 48 hours after it. A buyer turned away at the gate files a claim with proof, the seller can answer, and a person rules. With no claim, the seller is paid. A cancelled show refunds automatically.

Every ticket is checked first A barcode can be sold only once: our contract and our database refuse a second sale. Edited PDFs are flagged for a person. Claude reads the show, category and seat from the ticket text after personal data is removed; it fills in details and does not judge.

Two payment rails, one public record on Arbitrum In Indonesia, fans pay by QRIS in rupiah through Xendit, a licensed provider, and LummyLedger records every step of the order. For shows abroad, fans pay USDC from their own wallet with two signatures and no gas, and LummyEscrow locks it per listing. Once the claim window closes, anyone can release it to the seller, even if Lummy is down. We built that USDC checkout at Founder House.

Business. One platform fee per resale, shared with the organizer: 7.5% in total, 5% from the buyer and 2.5% from the seller, and the seller's 2.5% goes to the organizer that makes Lummy its official resale partner. That is still far below global resale sites. No organizer has signed yet, so today only the buyer pays: 5% (minimum Rp25,000), and the seller keeps the full price.

Status Live at lummy.id on Arbitrum Sepolia and Xendit test mode: no real money, no users and no revenue yet. Two verified contracts, 114 Foundry tests, Slither in CI. Next: a beta with ten fans, then one promoter pilot in December.

ハッカソンの進行状況

Since the founder-house-start tag (23 Oct, 09:53 SGT), 122 commits in the public repo: 198 files changed, 7,485 lines added. The contract source did not change. USDC checkout from the buyer's own wallet, for shows abroad, live on lummy.id. The buyer signs ERC-3009 and EIP-712; our operator locks the USDC in LummyEscrow and pays the gas, and any failure after funding refunds on chain. Claims and rulings on USDC orders work end to end. usdc:check: 57 of 57 on Arbitrum Sepolia. Tried with a real browser wallet (Rabby) on 24 Oct: 9.5 test USDC, two signatures, no transaction or gas from the wallet: https://sepolia.arbiscan.io/tx/0x16fbe1ca8519c97e7458848f052e9d6f6edc16943d345ccb0fc7fbe0f847abed **Sponsor tools.** Slither from Trail of Bits runs on both contracts in CI and fails on any untriaged medium or high finding; all 12 findings are triaged. Quicknode is our Arbitrum Sepolia RPC, with the public RPC as fallback. **Real catalogue.** The made-up shows are gone: real shows in Indonesia and abroad, a source for every price, and every listing labelled a sample. **Safer ticket checks.** A holder's name never reaches the AI. Every ticket in a multi-ticket PDF is read. A claim photo taken after the claim is flagged, and a ticket marked TEST or VOID goes to a person. In our latest run on 33 made-up tickets, the 31 sent to the AI came back with the right category, date, price and seat (the other 2 were rightly stopped before sending), and nothing personal was sent. **Honest labels.** Every page says when money is test money, and nothing offers a payout or organiser feature that is not live. **Ready for judges.** Demo accounts linked from the home page, sample ticket PDFs to try the checks, a bilingual letter of authorisation that takes an ID or passport number, and honest labels wherever a feature is not live yet. **Mentor feedback.** The pitch now opens the Arbitrum part with the on-chain escrow (table 1) and compares our fee with Viagogo's (table 3).

資金調達の状況

Pre-revenue and bootstrapped: we have not raised a round. Before Lummy, our earlier ticketing prototype on Lisk won a US$4,600 Lisk Spark grant; we do not count it as Lummy funding.
