The problem Hungry Frog Eat Coins solves

When developing games with Blockchain, we will encounter the following problems:

1. The experience is constantly interrupted because of having to constantly interact with the wallet and having to pay fees when interacting -> players have to deposit money to be able to play.
2. Poor security because playing the game requires connecting to a wallet and signing transactions. If the wallet is lost, all of the player's data will be lost.
   Solution:
   Use Thirdweb Account Abstraction and Smart Wallet combined with In-App Wallet to help players create an account associated with Email. No need to go through a wallet. All player data will be safe even if the player's wallet is lost.
   Using Thirdweb Account Abstraction and Smart Wallet also does not require players to pay fees or sign transactions -> providing a seamless and immersive experience.

Challenges I ran into

We had difficulty developing a smart contract that could rank players on the chain.
Then we found and consulted Youtube video tutorials from Sean and Thirdweb. And then we found a way.
Thanks Sean for your instructions.
