Basım Ne İşe Yarar?
Basım, mevcut bir token'ın yeni birimlerini oluşturur ve mint'in toplam arzını artırır.
Yalnızca mint yetkisi yeni token'lar basabilir. Hedef token account zaten mevcut olmalı ve aynı mint'e ait olmalıdır.
Token'lar Nasıl Basılır
Token'lar basmak için Token Program'ın MintTo veya MintToChecked
talimatı kullanılır.
Aşağıdaki örnekler MintToChecked kullanır; bu talimat, çağrıcının mint'in
ondalık basamaklarını sağlamasını gerektirir, böylece talimat basmadan önce
beklenen token hassasiyetini doğrulayabilir.
Native mint basımı desteklemez.
