Staking Basics

How Solana Staking Works

Stake Account: A special account that locks SOL and delegates it to a validator. Each stake account points to exactly one validator.

Rewards: Validators earn rewards for securing the network. These rewards are distributed to all stake accounts delegated to that validator.

Lifecycle: Create → Delegate → Earn Rewards → Deactivate → Withdraw

Why Choose Helius Validator

• 0% Commission: Keep 100% of your staking rewards
• High Performance: Reliable block production and minimal downtime
• Easy Integration: Optimized for the Helius SDK with built-in helpers

Timing & Epochs

• Activation: Stakes become active at the start of the next epoch (~2 days)
• Deactivation: Takes effect at the end of the current epoch
• Cooldown: Deactivated stakes can be withdrawn immediately after epoch end

​

Getting Started

Quick Start

Stake SOL in just 3 lines of code:

// 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}`);

The SDK automatically handles rent calculation and stake account creation. The 1.5 parameter is the amount in SOL you want to stake.

Complete Example

Full staking implementation with error handling:

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`);

​

SDK Methods Reference

createStakeTransaction(owner, amount)

Creates a complete staking transaction that can be signed and sent.

Parameters:

• owner (PublicKey): The wallet that will own the stake account
• amount (number): Amount of SOL to stake

Returns:

{
  serializedTx: string,        // Base58 encoded transaction
  stakeAccountPubkey: string   // New stake account address
}

Example:

const result = await helius.rpc.createStakeTransaction(
  payer.publicKey, 
  1.5  // 1.5 SOL
);

getStakeInstructions(owner, amount)

Returns just the instructions for staking (useful for custom transaction building).

Returns:

{
  instructions: TransactionInstruction[],
  stakeAccount: Keypair
}

Example:

const { instructions } = await helius.rpc.getStakeInstructions(
  payer.publicKey, 
  1.5
);

// Use with Smart Transactions
const signature = await helius.rpc.sendSmartTransaction(
  instructions, 
  [payer]
);

getHeliusStakeAccounts(wallet)

Retrieves all stake accounts delegated to the Helius validator for a wallet.

Example:

const accounts = await helius.rpc.getHeliusStakeAccounts(
  payer.publicKey.toBase58()
);

accounts.forEach(account => {
  const delegation = account.account.data.parsed.info.stake.delegation;
  console.log(`Account: ${account.pubkey}`);
  console.log(`Stake: ${delegation.stake / LAMPORTS_PER_SOL} SOL`);
});

createUnstakeTransaction(owner, stakeAccount)

Creates a transaction to deactivate (begin unstaking) a stake account.

Example:

const tx = await helius.rpc.createUnstakeTransaction(
  payer.publicKey,
  stakeAccountPubkey
);

const transaction = Transaction.from(bs58.decode(tx));
transaction.partialSign(payer);
await helius.connection.sendRawTransaction(transaction.serialize());

getWithdrawableAmount(stakeAccount, includeRent?)

Check how much SOL can be withdrawn from a deactivated stake account.

Parameters:

• includeRent (boolean): Whether to include rent-exempt amount

Example:

const available = await helius.rpc.getWithdrawableAmount(stakeAccountPubkey);
const total = await helius.rpc.getWithdrawableAmount(stakeAccountPubkey, true);

console.log(`Available now: ${available / LAMPORTS_PER_SOL} SOL`);
console.log(`Total balance: ${total / LAMPORTS_PER_SOL} SOL`);

createWithdrawTransaction(owner, stakeAccount, destination, amount)

Creates a transaction to withdraw SOL from a deactivated stake account.

Example:

const tx = await helius.rpc.createWithdrawTransaction(
  payer.publicKey,
  stakeAccountPubkey,
  destinationPubkey,
  withdrawAmount  // in lamports
);

​

Complete Staking Workflow

1. Create and Delegate

   // 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}`);
   
2. Monitor Your Stakes

   // 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'}`);
   });
   
3. Deactivate (Start Unstaking)

   // 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.');
   
4. Withdraw SOL

   // 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`);
   }

Advanced Patterns

Browser Integration

For browser applications using wallet adapters:

// 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()}`);

Batch Operations

Stake for multiple wallets efficiently:

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`);
}

Smart Transactions

Use Smart Transactions for better reliability and optimization:

// 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}`);

​

Important Notes

Epoch Timing: Solana epochs last ~2 days. Stakes activate at the next epoch start, and deactivation takes effect at the current epoch end.

Rent Considerations: Stake accounts need rent-exempt reserves (~0.00228 SOL). Withdrawing the full balance closes the account.

Hardware Wallets: Users will see two signature prompts - one for the stake account (pre-signed) and one for the fee payer. Design your UX accordingly.

Quick Reference

Need a quick reminder? Here are the essential methods:

// 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
