Init code hash shine ainihin keccak256 hash na bytecode ɗin kwangilar.
Amfani da Init Code
Ana buƙatar init code hash "Tunda lissafin adireshi ya dogara da hashing
init code. Init code shine lambar da, idan an aiwatar da ita, tana samar

Amfani da Init Code
Babban amfani da init code shine don haƙo adireshi. Kuna iya duba https://github.com/0age/create2crunch don misalin yadda za mu iya amfani da CREATE2 da init code na kwangila don 'haƙo' adireshi mafi inganci don turawa kwangila.
Ga wani sauƙi bash script wanda ke amfani da forge don samar muku da code init hash:
