This time, I participated in the Klaytn Hackaton, and this lecture was really helpful. In fact, after I found out about this lecture, I was able to find out about the existence of the Klaytn Hackathon. LOL The IDE is well-prepared to check how Klaytn transactions occur, and I had a fun time creating a bApp even though it was being tested. Thank you for providing a great lecture!! More detailed information is available at https://docs.klaytn.com/! Please come see the bApp my team created using Klaytn~ https://www.youtube.com/watch?v=aUh57mAp25s&t=4s
