## Instalasi & Penyiapan

<CodeGroup>
  ```bash npm theme={"system"}
  npm install helius-sdk @solana/web3.js bs58
  ```

  ```bash yarn   theme={"system"}
  yarn add helius-sdk @solana/web3.js bs58
  ```

  ```bash pnpm theme={"system"}
  pnpm add helius-sdk @solana/web3.js bs58
  ```
</CodeGroup>

<CodeGroup>
  ```typescript Setup theme={"system"}
  import { Helius } from 'helius-sdk';
  import { Keypair, Transaction } from '@solana/web3.js';
  import bs58 from 'bs58';

  // Initialize Helius client
  const helius = new Helius('YOUR_API_KEY');

  // Your wallet keypair (load from your secure storage)
  const payer = Keypair.fromSecretKey(/* your secret key */);
  ```
</CodeGroup>

## Dasar-Dasar Staking

<AccordionGroup>
  <Accordion title="How Solana Staking Works">
    **Akun Stake**: Akun khusus yang mengunci SOL dan mendelegasikannya kepada validator. Setiap akun stake menunjuk tepat ke satu validator.

    **Imbalan**: Validator memperoleh imbalan karena mengamankan jaringan. Imbalan ini didistribusikan ke semua akun stake yang didelegasikan kepada validator tersebut.

    **Siklus**: Buat → Delegasikan → Dapatkan Imbalan → Nonaktifkan → Tarik
  </Accordion>

  <Accordion title="Why Choose Helius Validator">
    * **Komisi 0%**: Dapatkan 100% imbalan staking Anda
    * **Performa Tinggi**: Produksi blok yang andal dan waktu henti minimal
    * **Integrasi Mudah**: Dioptimalkan untuk Helius SDK dengan helper bawaan
  </Accordion>

  <Accordion title="Timing & Epochs">
    * **Aktivasi**: Stake menjadi aktif pada awal epoch berikutnya (\~2 hari)
    * **Penonaktifan**: Mulai berlaku pada akhir epoch saat ini
    * **Pendinginan**: Stake yang dinonaktifkan dapat ditarik segera setelah epoch berakhir
  </Accordion>
</AccordionGroup>

## Memulai

<Tabs>
  <Tab title="Quick Start">
    Lakukan staking SOL hanya dengan 3 baris kode:

    ```typescript theme={"system"}
    // 1. Create the staking transaction
    const { serializedTx, stakeAccountPubkey } = 
      await helius.rpc.createStakeTransaction(payer.publicKey, 1.5);

    // 2. Sign and send
    const tx = Transaction.from(bs58.decode(serializedTx));
    tx.partialSign(payer);
    const signature = await helius.connection.sendRawTransaction(tx.serialize());

    console.log(`Staked! Transaction: ${signature}`);
    console.log(`Stake Account: ${stakeAccountPubkey}`);
    ```

    <Info>
      SDK secara otomatis menangani penghitungan biaya sewa dan pembuatan akun stake. Parameter `1.5` adalah jumlah SOL yang ingin Anda stake.
    </Info>
  </Tab>

  <Tab title="Complete Example">
    Implementasi staking lengkap dengan penanganan kesalahan:

    ```typescript theme={"system"}
    async function stakeSOL(amountInSol: number) {
      try {
        // Create staking transaction
        const { serializedTx, stakeAccountPubkey } = 
          await helius.rpc.createStakeTransaction(payer.publicKey, amountInSol);
        
        // Deserialize and sign transaction
        const transaction = Transaction.from(bs58.decode(serializedTx));
        transaction.partialSign(payer);
        
        // Send transaction
        const signature = await helius.connection.sendRawTransaction(
          transaction.serialize(),
          { 
            skipPreflight: false,
            preflightCommitment: 'confirmed'
          }
        );
        
        // Wait for confirmation
        await helius.connection.confirmTransaction(signature, 'confirmed');
        
        return {
          signature,
          stakeAccount: stakeAccountPubkey,
          amount: amountInSol
        };
        
      } catch (error) {
        console.error('Staking failed:', error);
        throw error;
      }
    }

    // Usage
    const result = await stakeSOL(2.5);
    console.log(`Successfully staked ${result.amount} SOL`);
    ```

## Alur Kerja Staking Lengkap

<Steps>
  <Step title="Create and Delegate">
    ```typescript theme={"system"}
    // Stake 2 SOL to Helius validator
    const { serializedTx, stakeAccountPubkey } = 
      await helius.rpc.createStakeTransaction(payer.publicKey, 2.0);

    const tx = Transaction.from(bs58.decode(serializedTx));
    tx.partialSign(payer);

    const signature = await helius.connection.sendRawTransaction(tx.serialize());
    console.log(`Stake created: ${stakeAccountPubkey}`);
    ```
  </Step>

  <Step title="Monitor Your Stakes">
    ```typescript theme={"system"}
    // Get all your Helius stake accounts
    const accounts = await helius.rpc.getHeliusStakeAccounts(
      payer.publicKey.toBase58()
    );

    console.log(`You have ${accounts.length} active stake accounts`);

    accounts.forEach((account, index) => {
      const info = account.account.data.parsed.info;
      const delegation = info.stake.delegation;
      
      console.log(`Stake ${index + 1}:`);
      console.log(`  Amount: ${delegation.stake / LAMPORTS_PER_SOL} SOL`);
      console.log(`  Activated: Epoch ${delegation.activationEpoch}`);
      console.log(`  Status: ${info.meta.lockup.unixTimestamp === 0 ? 'Active' : 'Locked'}`);
    });
    ```
  </Step>

  <Step title="Deactivate (Start Unstaking)">
    ```typescript theme={"system"}
    // Begin the unstaking process
    const unstakeTx = await helius.rpc.createUnstakeTransaction(
      payer.publicKey,
      stakeAccountPubkey
    );

    const tx = Transaction.from(bs58.decode(unstakeTx));
    tx.partialSign(payer);

    await helius.connection.sendRawTransaction(tx.serialize());
    console.log('Deactivation started. Will be withdrawable next epoch.');
    ```
  </Step>

  <Step title="Withdraw SOL">
    ```typescript theme={"system"}
    // Check withdrawable amount
    const withdrawable = await helius.rpc.getWithdrawableAmount(
      stakeAccountPubkey, 
      true  // include rent
    );

    if (withdrawable > 0) {
      // Create withdrawal instruction
      const withdrawInstruction = helius.rpc.getWithdrawInstruction(
        payer.publicKey,
        stakeAccountPubkey,
        payer.publicKey,  // withdraw to same wallet
        withdrawable
      );
      
      // Send using Smart Transactions for better reliability
      const signature = await helius.rpc.sendSmartTransaction(
        [withdrawInstruction], 
        [payer]
      );
      
      console.log(`Withdrawn ${withdrawable / LAMPORTS_PER_SOL} SOL`);
    }
    ```
  </Step>
</Steps>

## Pola Lanjutan

<Tabs>
  <Tab title="Browser Integration">
    Untuk aplikasi peramban yang menggunakan adaptor dompet:

    ```typescript theme={"system"}
    // Get instructions instead of full transaction
    const { instructions, stakeAccount } = await helius.rpc.getStakeInstructions(
      wallet.publicKey,
      stakeAmount
    );

    // Let the wallet handle transaction building and signing
    const transaction = new Transaction().add(...instructions);

    // Sign with wallet adapter
    const signature = await wallet.sendTransaction(transaction, connection);

    console.log(`Stake account: ${stakeAccount.publicKey.toBase58()}`);
    ```
  </Tab>

  <Tab title="Batch Operations">
    Lakukan staking secara efisien untuk beberapa dompet:

    ```typescript theme={"system"}
    async function batchStake(wallets: Keypair[], amount: number) {
      const promises = wallets.map(async (wallet) => {
        try {
          const { serializedTx, stakeAccountPubkey } = 
            await helius.rpc.createStakeTransaction(wallet.publicKey, amount);
          
          const tx = Transaction.from(bs58.decode(serializedTx));
          tx.partialSign(wallet);
          
          return helius.connection.sendRawTransaction(tx.serialize());
        } catch (error) {
          console.error(`Failed to stake for ${wallet.publicKey.toBase58()}:`, error);
          return null;
        }
      });
      
      const results = await Promise.allSettled(promises);
      const successful = results.filter(r => r.status === 'fulfilled').length;
      
      console.log(`Successfully staked for ${successful}/${wallets.length} wallets`);
    }
    ```
  </Tab>

  <Tab title="Smart Transactions">
    Gunakan Smart Transactions untuk keandalan dan pengoptimalan yang lebih baik:

    ```typescript theme={"system"}
    // Get individual instructions
    const { instructions } = await helius.rpc.getStakeInstructions(
      payer.publicKey,
      2.5
    );

    // Send with Smart Transaction features:
    // - Automatic priority fee optimization
    // - Retry logic with backoff
    // - Better error handling
    const signature = await helius.rpc.sendSmartTransaction(
      instructions,
      [payer],
      {
        skipPreflight: false,
        maxRetries: 3
      }
    );

    console.log(`Smart transaction sent: ${signature}`);
    ```
  </Tab>
</Tabs>

## Catatan Penting

<Warning>
  **Waktu Epoch**: Epoch Solana berlangsung selama \~2 hari. Stake diaktifkan pada awal epoch berikutnya, sedangkan penonaktifan mulai berlaku pada akhir epoch saat ini.
</Warning>

<Note>
  **Pertimbangan Biaya Sewa**: Akun stake memerlukan cadangan bebas sewa (\~0,00228 SOL). Penarikan seluruh saldo akan menutup akun.
</Note>

<Tip>
  **Dompet Perangkat Keras**: Pengguna akan melihat dua permintaan tanda tangan—satu untuk akun stake (ditandatangani sebelumnya) dan satu untuk pembayar biaya. Rancang UX Anda dengan mempertimbangkan hal ini.
</Tip>

## Referensi Singkat

Perlu pengingat singkat? Berikut metode-metode penting:

```typescript theme={"system"}
// Stake SOL
await helius.rpc.createStakeTransaction(owner, amountInSol);

// Check your stakes  
await helius.rpc.getHeliusStakeAccounts(ownerAddress);

// Start unstaking
await helius.rpc.createUnstakeTransaction(owner, stakeAccount);

// Check withdrawable amount
await helius.rpc.getWithdrawableAmount(stakeAccount, includeRent);

// Withdraw SOL
helius.rpc.getWithdrawInstruction(owner, stakeAccount, destination, amount);
```
