I solved this challenge at the last moment, but made a stupid mistake on the exploit contract that I transferred ETH to a wrong address instead of the wallet. Then I have to reset the challenge which takes quite long and have to wait for the pending transaction for front running. Then the CTF ended and I could not submit the flag on time ?
