Aktarılamaz Tokenlar

InitializeNonTransferableMint uzantısını etkinleştirme

InitializeNonTransferableMint tokenların basıldıktan sonra token account'lar arasında transfer edilmesini engeller. Bir kez basıldıktan sonra, tokenlar kalıcı olarak token account'ta kalır. Ancak, token account sahibi yine de tokenları yakabilir ve bakiye sıfıra ulaştığında token account'ı kapatabilir.
