Chapter 5: Summary

Congratulations, you have successfully completed the interaction between the front-end and the smart contract, and now users can play TicTacToe entirely on Bitcoin!

You can continue to improve this dApp, for example:

  • Build a back-end for it to support multiple pair of players
  • Move the UTXO management from front-end, as it is now, to back-end
  • Support more wallets
  • Increase the board size, such as 5 X 5

The code of this course is at: Bitcoin onchain App Tutorial.

Look forward to the killer dApp you build on Bitcoin.
