Problem we faced（直面した課題）

• Build in limited time
  • Idea generation began after the presentation of the hackathon evaluation criteria, and implementation began at 6:00 p.m. on the second day.
  • The implementation members were familiar with web2, but this was the first time for them to implement a web3 product.
  • With little time to spare, they completed the implementation of the core functionality of the contract and part of the front-end implementation.
• The mumbai network was congested, making it difficult to check operation and create a demo.
