string
Giao dịch Solana được mã hóa bằng Base58 hoặc Base64 cần ước tính mức phí ưu tiên tối ưu.
API sẽ phân tích các chỉ thị và tài khoản cụ thể trong giao dịch này để cung cấp
ước tính phí chính xác dựa trên điều kiện mạng hiện tại và độ phức tạp tính toán.
Nên dùng khi kết quả ước tính sẽ được dùng để đặt phí cho giao dịch bạn sắp gửi.
Bỏ qua cả trường này và accountKeys để nhận kết quả ước tính toàn cục trên toàn bộ hoạt động mạng
gần đây, mô tả điều kiện mạng thay vì giao dịch của bạn.
array
Mảng khóa công khai của tài khoản Solana cần ước tính phí ưu tiên (thay cho việc cung cấp một giao dịch).
Bao gồm các tài khoản có thể ghi mà giao dịch của bạn sẽ khóa: Solana định giá phí ưu tiên theo từng
tài khoản có thể ghi, vì vậy đây là những tài khoản mà bạn phải cạnh tranh quyền truy cập.

boolean
Khi là true, trả về mức ước tính đầy đủ cho tất cả các mức ưu tiên, từ tối thiểu đến tối đa
number
Số slot gần đây trên blockchain Solana cần phân tích để ước tính phí chính xác (1-150)
boolean
Khi là true, bao gồm các giao dịch bỏ phiếu trong phép tính phí để phân tích toàn diện hơn
boolean
Khi là true, trả về mức phí tối ưu được đề xuất dựa trên điều kiện hiện tại của mạng Solana
boolean
Khi là true, các slot không có giao dịch được tính là slot có mức phí bằng 0 trong phép tính
