Đóng băng tài khoản
Đóng băng tài khoản
Lệnh
FreezeAccount
ngăn chặn tất cả các giao dịch chuyển token hoặc đốt token từ một token account
cụ thể. Khi đã bị đóng băng, tài khoản không thể gửi token, nhận token, hoặc bị
đóng cho đến khi nó được giải đóng. Chỉ có freeze authority của mint token mới
có thể đóng băng tài khoản. Nếu freeze authority bị thu hồi (đặt thành null)
trên mint account, token sẽ không bao giờ có thể bị đóng băng.
Token Program và Token Extension Program có cách triển khai tương tự nhau để đạt được cùng một chức năng.
