Всем привет, скажите плз, зачем используется "\x19Ethereum Signed Message:\n32" ? https://solidity-by-example.org/signature/ В
этом примере эту строку используют для подписи хэша. Но зачем подписывать хэш этой строкой и потом бросать в ecrecover вместе с подписью, сделанной через метамаск? По идее туда надо забросить хэш текста и подпись сделанную приватным ключем
