🧙Solana Actions

Execute transactions on Solana vaults including deposits, withdrawals, and queries. All operations follow the same pattern as EVM vaults for consistency.

Overview

Solana vault interactions use the same pattern as EVM:

1. Use sdk.getVault() to query vault data

2. Use sdk.solana.vaultDeposit() to deposit

3. Use sdk.solana.vaultRedeem() to withdraw

The SDK handles all Solana-specific complexities (PDAs, token accounts, etc.) automatically.

Setup

Basic Initialization

Include Solana RPC endpoint when initializing the SDK:

import { AugustSDK } from '@augustdigital/sdk';

const sdk = new AugustSDK({
  providers: {
    -1: 'https://api.mainnet-beta.solana.com', // Solana Mainnet
  },
});

// Access Solana adapter
const solana = sdk.solana;

Custom RPC Endpoint

const sdk = new AugustSDK({
  providers: {
    -1: 'https://solana-mainnet.g.alchemy.com/v2/YOUR_KEY',
  },
});

For Write Operations

To execute transactions, you need to set a wallet provider:

import { useWallet } from '@solana/wallet-adapter-react';

// In your React component
const { publicKey, signTransaction } = useWallet();

// Set wallet for signing transactions
if (publicKey && signTransaction) {
  sdk.solana.setWalletProvider(publicKey, signTransaction);
}

Adapter API

Methods

setWalletProvider()

Set the wallet provider for write operations.

sdk.solana.setWalletProvider(
  publicKey: PublicKey | string,
  signTransaction: (tx: Transaction) => Promise<Transaction>
): void

Parameters:

• publicKey: User's Solana public key

• signTransaction: Function to sign transactions (from wallet adapter)

Example:

import { useWallet } from '@solana/wallet-adapter-react';

function MyComponent() {
  const { publicKey, signTransaction } = useWallet();

  useEffect(() => {
    if (publicKey && signTransaction) {
      sdk.solana.setWalletProvider(publicKey, signTransaction);
    }
  }, [publicKey, signTransaction]);
}

Get Vault Data

Query Solana vault information using the same sdk.getVault() method as EVM vaults.

sdk.getVault({
  vault: string;  // Solana program ID
  chainId?: number;  // -1 for mainnet
  options?: {
    solanaWallet?: string;  // For user position data
  };
}): Promise<IVault>

Parameters

Parameter	Type	Required	Description
vault	string	Yes	Solana vault program ID
options.solanaWallet	string	No	User's Solana public key for position data

Example

// Get vault details
const vault = await sdk.getVault({
  vault: 'VaultProgramId...',
  chainId: -1, // Solana mainnet
});

console.log('Name:', vault.name);
console.log('Version:', vault.version); // "sol-0"
console.log('Total Assets:', vault.totalAssets.normalized);
console.log('APY:', vault.apy.apy);
console.log('Deposit Token:', vault.depositAssets[0].symbol);

// Get vault with user position
const vaultWithPosition = await sdk.getVault({
  vault: 'VaultProgramId...',
  chainId: -1,
  options: {
    solanaWallet: 'UserPublicKey...',
  },
});

if (vaultWithPosition.position) {
  console.log('Your balance:', vaultWithPosition.position.walletBalance.normalized);
}

Get All Solana Vaults

const solanaVaults = await sdk.getVaults({
  chainIds: [-1], // Filter to Solana mainnet only
  solanaWallet: 'UserPublicKey...', // Optional: include positions
});

solanaVaults.forEach(vault => {
  console.log(`${vault.name}: ${vault.totalAssets.normalized} TVL`);
});

Get User Positions

const positions = await sdk.getVaultPositions({
  solanaWallet: 'UserPublicKey...',
  chainId: -1,
});

positions.forEach(position => {
  console.log(`Vault: ${position.vault}`);
  console.log(`Balance: ${position.walletBalance.normalized}`);
});

Vault Deposit

Deposit tokens into a Solana vault. The SDK automatically handles token accounts, PDAs, and Anchor program interactions.

sdk.solana.vaultDeposit({
  vault: string;
  amount: string | number | bigint;
  wallet: string;
  wait?: boolean;
}): Promise<string>

Parameters

Parameter	Type	Required	Description
vault	string	Yes	Solana vault program ID
amount	string | number | bigint	Yes	Amount to deposit
wallet	string	Yes	User's Solana public key
wait	boolean	No	Wait for confirmation (default: false)

Returns

Transaction signature as string

Example

import { useWallet } from '@solana/wallet-adapter-react';

// In your React component
const { publicKey, signTransaction } = useWallet();

// Set wallet provider (once per session)
if (publicKey && signTransaction) {
  sdk.solana.setWalletProvider(publicKey, signTransaction);
}

// Get vault info
const vault = await sdk.getVault({
  vault: 'VaultProgramId...',
  chainId: -1,
});

// Deposit
const signature = await sdk.solana.vaultDeposit({
  vault: vault.address,
  amount: '100', // 100 tokens
  wallet: publicKey.toString(),
  wait: true,
});

console.log('Deposit successful:', signature);

Behavior

The SDK automatically:

1. Fetches vault state and PDAs

2. Gets or creates associated token accounts

3. Handles token approvals if needed

4. Converts amount to proper decimals

5. Submits transaction via wallet adapter

6. Optionally waits for confirmation

Vault Withdraw

Request withdrawal from a Solana vault.

sdk.solana.vaultRedeem({
  vault: string;
  amount: string | number | bigint;
  wallet: string;
  wait?: boolean;
}): Promise<string>

Parameters

Parameter	Type	Required	Description
vault	string	Yes	Solana vault program ID
amount	string | number | bigint	Yes	Amount of shares to redeem
wallet	string	Yes	User's Solana public key
wait	boolean	No	Wait for confirmation

Returns

Transaction signature as string

Example

// Get user's vault balance
const position = await sdk.getVaultPositions({
  solanaWallet: publicKey.toString(),
  chainId: -1,
});

if (position[0].walletBalance.raw === '0') {
  throw new Error('No balance to withdraw');
}

// Request redemption
const signature = await sdk.solana.vaultRedeem({
  vault: 'VaultProgramId...',
  amount: '50', // Redeem 50 shares
  wallet: publicKey.toString(),
  wait: true,
});

console.log('Redemption requested:', signature);

      console.error('Deposit failed:', error);
      throw error;
    } finally {
      setLoading(false);
    }
  };

  return (
    <button 
      onClick={() => deposit('VaultProgramId...', '100')} 
      disabled={loading || !publicKey}
    >
      {loading ? 'Depositing...' : 'Deposit 100 Tokens'}
    </button>
  );
}

Complete Withdrawal Flow

function SolanaVaultWithdraw() {
  const { publicKey, signTransaction } = useWallet();

  const sdk = new AugustSDK({
    providers: {
      -1: 'https://api.mainnet-beta.solana.com',
    },
  });

  const withdraw = async (vaultId: string) => {
    if (!publicKey || !signTransaction) {
      throw new Error('Wallet not connected');
    }

    try {
      // 1. Set wallet provider
      sdk.solana.setWalletProvider(publicKey, signTransaction);

      // 2. Check user's position
      const position = await sdk.getVaultPositions({
        solanaWallet: publicKey.toString(),
        chainId: -1,
      });

      if (!position[0] || position[0].walletBalance.raw === '0') {
        throw new Error('No balance to withdraw');
      }

      const balance = position[0].walletBalance.normalized;
      console.log(`Withdrawing ${balance} shares`);

      // 3. Execute redemption
      const signature = await sdk.solana.vaultRedeem({
        vault: vaultId,
        amount: balance, // Withdraw all
        wallet: publicKey.toString(),
        wait: true,

    }
  };

  return (
    <button onClick={() => withdraw('VaultProgramId...')}>
      Withdraw All
    </button>
  );
}

Query Vault Before Depositing

// 1. Get vault info
const vault = await sdk.getVault({
  vault: 'VaultProgramId...',
  chainId: -1,
});

// 2. Check if deposits are enabled
if (vault.isDepositPaused) {
  throw new Error('Vault deposits are paused');
}

// 3. Show user the vault details
console.log(`Vault: ${vault.name}`);
console.log(`APY: ${vault.apy.apy}%`);
console.log(`TVL: ${vault.totalAssets.normalized}`);
console.log(`Deposit token: ${vault.depositAssets[0].symbol}`);

// 4. Deposit
await sdk.solana.vaultDeposit({
  vault: vault.address,
  amount: '100',
  wallet: publicKey.toString(),
  wait: true,
});

Advanced Operations

For advanced use cases, the Solana adapter exposes low-level methods and utilities.

Direct Program Access

Access Solana connection and provider for custom operations:

// Get connection
const connection = sdk.solana.connection;
const balance = await connection.getBalance(publicKey);

// Get Anchor provider
const provider = sdk.solana.provider;

// Get program instance
import { vaultIdl } from '@augustdigital/sdk';
const program = sdk.solana.getProgram(vaultIdl);

// Query vault account directly
const vaultState = await program.account.vault.fetch(vaultPda);

Utility Functions

import { Solana } from '@augustdigital/sdk';

deriveShareMintPda()

Derive the share mint PDA for a vault.

const shareMintPda = Solana.utils.deriveShareMintPda(
  'VaultProgramId...'
);

console.log('Share Mint PDA:', shareMintPda.toString());

getToken()

Get token metadata from mint address.

const token = await Solana.utils.getToken({
  mintAddress: 'MintPublicKey...',
  endpoint: 'https://api.mainnet-beta.solana.com',
  connection: sdk.solana.connection,
});

console.log('Symbol:', token.symbol);
console.log('Decimals:', token.decimals);
console.log('Supply:', token.supply);

getVaultStateReadOnly()

Get vault state without a wallet provider.

const vaultState = await Solana.utils.getVaultStateReadOnly({
  vaultProgramId: 'VaultProgramId...',
  idl: vaultIdl,
  endpoint: 'https://api.mainnet-beta.solana.com',
  connection: sdk.solana.connection,
});

getProvider()

Create an Anchor provider with wallet.

import { PublicKey } from '@solana/web3.js';

const provider = Solana.utils.getProvider({
  network: 'mainnet-beta',
  connection: sdk.solana.connection,
  publicKey: new PublicKey('UserPublicKey...'),
  signTransaction: signTransactionFunction,
});

getReadOnlyProvider()

Create a read-only Anchor provider.

const provider = Solana.utils.getReadOnlyProvider({
  network: 'mainnet-beta',
  connection: sdk.solana.connection,
});

getProgram()

Create an Anchor program instance.

const program = Solana.utils.getProgram({
  network: 'mainnet-beta',
  provider: anchorProvider,
  idl: programIdl,
});

Constants

The Solana adapter provides useful constants:

import { Solana } from '@augustdigital/sdk';

Vault IDL

const vaultIdl = Solana.constants.vaultIdl;

Program IDs

const programIds = Solana.constants.programIds;

console.log('Vault Program:', programIds.vaultProgram);

Fallback Values

const fallbackDecimals = Solana.constants.fallbackDecimals; // 9
const fallbackNetwork = Solana.utils.fallbackNetwork; // 'mainnet-beta'

Error Handling

Connection Errors

try {
  const vaultState = await sdk.solana.getVaultState('VaultId...', vaultIdl);
} catch (error) {
  if (error.message.includes('404')) {
    console.error('Vault program not found');
  } else if (error.message.includes('Network request failed')) {
    console.error('RPC connection failed');
  } else {
    console.error('Unknown error:', error);
  }
}

Transaction Errors

try {
  await handleSolanaDeposit({
    connection: sdk.solana.connection,
    provider: sdk.solana.provider,
    vaultProgramId: 'VaultId...',
    amount: 1000000000,
    userTokenAccount: 'TokenAccount...',
    idl: vaultIdl,
  });
} catch (error) {
  if (error.message.includes('User rejected')) {
    console.error('Transaction cancelled by user');
  } else if (error.message.includes('insufficient funds')) {
    console.error('Not enough SOL for transaction');
  } else {
    console.error('Transaction failed:', error);
  }
}
