# Setoran

> Panduan untuk menyetor aset SOL, SPL, atau Token 2022 ke saldo privat, lengkap dengan contoh kode penuh.

1. Setoran memindahkan token dari saldo Solana publik pengguna ke saldo privat milik sendiri atau orang lain.
2. Setoran dikirim dalam satu transaksi Solana ke alamat dompet Solana.

#### Setoran: Bagian yang Privat

| Jumlah                       | Publik      | Jumlah yang disetorkan terlihat secara onchain         |
| Alamat dompet tujuan         | Publik      | Alamat dompet tujuan terlihat secara onchain           |
| Saldo privat yang dihasilkan | Privat      | Saldo privat yang dihasilkan dienkripsi secara onchain |

<Info>
  Ring tanpa izin bersifat rahasia, dengan jumlah dan aset yang dienkripsi.
  Ring khusus dapat dikonfigurasi sebagai rahasia atau anonim (pengirim, penerima, aset, dan jumlah dienkripsi).

## Cara Kerja Setoran

Setoran adalah transfer Solana publik yang menghasilkan saldo privat.

1. Saldo SOL atau SPL pengguna bersifat publik secara on-chain.
2. Dompet menetapkan jumlah dan penerima, membuat setoran, lalu pemilik menandatanganinya. Setoran tidak meminta bukti ZK.
3. Runtime Solana memverifikasi tanda tangan dan memanggil Solana Privacy Program.
4. Aplikasi melacak status melalui hash transaksi Solana.

        ### Prasyarat

        <Info>
          Contoh TypeScript memerlukan Node.js 24 atau versi yang lebih baru, pnpm 11.18.0, dan Solana CLI.
        </Info>

        ```bash theme={"system"}
        pnpm add 'git+ssh://git@github.com/helius-labs/zolana.git#v0.3.0-alpha&path:/sdk-libs/ts' @solana/kit@^8.3.0
