Loyalty Ledger tracks fan loyalty on-chain with Solana

Loyalty Ledger tracks fan loyalty on-chain with Solana

Original: Every Sports App Resets Your Streak Eventually. Mine Can't. 🔒⚡

Short summary

A weekend project submission called Loyalty Ledger that stores fan check-in streaks, badges, and history on the Solana blockchain rather than a centralized database. The FIFA World Cup path is fully functional with real on-chain writes, while NBA and other sports are stubbed. Users connect a Phantom wallet, check in via transactions, and can claim SPL token badges.

  • •Loyalty Ledger stores fan streaks and badges on Solana, not a centralized DB
  • •FIFA World Cup path is fully functional with real on-chain transactions and SPL token badges
  • •NBA and other sports are stubbed with sample data, clearly labeled as non-functional

Generated with AI, which can make mistakes.
