# About TON Payments Hack-a-TON is a regional hackathon designed specifically for builders across Latin America who want to create real, usable payments products on TON. Whether you’re into Telegram bots, mini-apps, or crypto-native checkout flows — this is your playground. # Ideas & Use Cases ### Your project **must involve product development** and be focused on **payments within the TON ecosystem**. You’re welcome to innovate beyond the list below, but here are some ideas to get you started: 1. **Remittances & P2P Transfers** Brazil has a large diaspora and significant intercity money movement needs. - Use case: Build a Telegram mini-app that lets users send and receive stablecoins (e.g. jUSDT) with live BRL conversion, using @wallet. 2. **QR-Based Payments for Small Merchants** Many small vendors use Pix and WhatsApp. Offer them a Web3-native alternative. - Use case: Create a QR-code payment bot that allows small merchants to accept stablecoins and track orders via Telegram. 3. **Bill Splitting for Groups** Common in Brazilian social culture (e.g. splitting bar tabs, Airbnb). - Use case: A Telegram bot that splits payments among friends, tracks who paid, and lets users settle with Toncoin/stables. 4. **Tipping & Creator Payments** Support content creators and community managers directly in Telegram. - Use case: A bot that allows tipping in Toncoin across groups and channels, with dashboards for creators. 5. **Telegram Commerce Checkout** Allow checkout flows in Telegram mini-apps with TON payments. - Use case: Build a plug-and-play “Pay with TON” checkout for Telegram stores or gaming bots. 6. **Recurring Subscriptions** Many users subscribe to gyms, content, or services monthly. - Use case: A subscription manager in Telegram that automates recurring Toncoin or stablecoin payments. 7. **Gaming Rewards Wallet** Brazil has a huge mobile gaming market. - Use case: A Telegram-integrated wallet that lets users earn, swap, and spend in-game rewards in Toncoin. 8. **“Pix-to-TON” Off-ramp Aggregator** Enable Pix payouts for users receiving crypto. - Use case: An aggregator bot that routes stablecoin payouts to local providers who do Pix off-ramps. 9. **Cashback or Loyalty Program** Many Brazilian users are used to cashback via Nubank, MercadoPago, etc. Use case: A mini-app that gives Toncoin cashback on purchases at local or online stores, integrated with Telegram. 10. **Credit and BNPL** Payments in installments are an everyday thing for Brazilians. - Use case: A service or infrastructure that allow for crypto spending in installments. # Prizes TON Payments Hack-a-TON will select 5 winners that present the best submissions. 🥇 1st place: 5,000 USDT 🥈 2nd place: 2,500 USDT 🥉 3rd place: 1,500 USDT 🏅 4th place: 750 USDT 🏅 5th place: 250 USDT *Please note: All prizes will be paid in USDT on TON or other cryptocurrency as determined by the Organizer at its sole discretion.
