Bagimana cara mengirim SPL-Tokens

Gunakan Token Program untuk mentransfer SPL Tokens. Untuk dapat mengirimkan sebuah SPL token, anda perlu mengetahui alamat dari SPL token account itu. Anda dapat mendapatkan alamat dan mengirimkan token-token seperti contoh berikut.

Bagaimana cara mengkalkulasi biaya transaksi

Kalkulasi biaya transaksi didapat dari jumlah signatures sebuah transaksi yang diperlukan. Selama anda tidak membuat account, ini akan menjadi biaya final transaksi. Info lebih lanjut tentang biaya untuk membuat sebuah account, dapat dilihat di calculating rent exemption

Dua contoh dibawah ini memperlihatkan dua cara yang tersedia saat ini untuk mengkalkulasi estimasi biaya transaksi.

Contoh pertama menggunakan getEstimatedFee, yang adalah method baru di dalam class Transaction, sedangkan contoh kedua menggunakan getFeeForMessage yang mengganti getFeeCalculatorForBlockhash di dalam Connection class.

Bagaimana menambah catatan ke dalam sebuah transaksi

Setiap transaksi dapat menambahkan catatan dengan memanfaatkan memo program. Untuk saat ini programID dari Memo Program harus ditambahkan mannually MemoSq4gqABAXKb96qnH8TysNcWxMyWCqXgDLGmfcHr.

Bagaimana cara merubah perhitungan budget untuk sebuah transaksi

Perhitungan budget untuk sebuah single transaksi dapat dirubah dengan menambahkan sebuah panggilan instruksi ke Compute Budget Program. Secara default, perhitungan budget diset dari 200k compute units * jumlah instruksi-instruksi, dengan maksimal1.4M compute units. Semakin sedikit perhitungan yang digunakan, semakin kecil biaya transaksi.

Note: Untuk merubah perhitungan budget sebuah transaksi, anda harus membuat instruksi pertama dari tiga instruksi pertama sebuah transaksi yang membuat budget.
