Voltr Vault Integration

Solana Agent Kit provides comprehensive integration with Voltr vaults for managing deposits, withdrawals, and viewing position values. The integration supports both Token Program and Token-2022 assets.

​

Key Features

• Strategy deposits
• Strategy withdrawals
• Position value tracking
• Token-2022 support
• Remaining accounts handling
• LangChain tool integration

​

Basic Usage

​

Getting Position Values

const values = await agent.voltrGetPositionValues(
  new PublicKey("vault_address")
);

​

Depositing into a Strategy

const signature = await agent.voltrDepositStrategy(
  new BN("1000000"),  // Amount in base units
  new PublicKey("vault_address"),
  new PublicKey("strategy_address")
);

​

Withdrawing from a Strategy

const signature = await agent.voltrWithdrawStrategy(
  new BN("1000000"),  // Amount in base units
  new PublicKey("vault_address"),
  new PublicKey("strategy_address")
);

​

Input Parameters

​

Strategy Operation Parameters

interface StrategyParams {
  depositAmount?: BN;      // Amount to deposit
  withdrawAmount?: BN;     // Amount to withdraw
  vault: PublicKey;        // Vault address
  strategy: PublicKey;     // Strategy address
}

​

Remaining Accounts Structure

interface RemainingAccount {
  pubkey: string;         // Account public key
  isSigner: boolean;      // Is signer flag
  isWritable: boolean;    // Is writable flag
}

​

LangChain Integration

Solana Agent Kit provides several LangChain tools for Voltr operations:

​

Get Position Values Tool

import { SolanaVoltrGetPositionValues } from 'solana-agent-kit';

const getPositionTool = new SolanaVoltrGetPositionValues(agent);

// Tool input: vault address as string
const input = "vault_address";

// Tool returns JSON string with position values

​

Deposit Strategy Tool

import { SolanaVoltrDepositStrategy } from 'solana-agent-kit';

const depositTool = new SolanaVoltrDepositStrategy(agent);

// Tool input format (JSON string):
const input = JSON.stringify({
  depositAmount: "1000000",
  vault: "vault_address",
  strategy: "strategy_address"
});

// Tool returns JSON response:
{
  status: "success",
  message: "Deposited 1000000 into strategy successfully",
  transaction: "transaction_signature"
}

​

Withdraw Strategy Tool

import { SolanaVoltrWithdrawStrategy } from 'solana-agent-kit';

const withdrawTool = new SolanaVoltrWithdrawStrategy(agent);

// Tool input format (JSON string):
const input = JSON.stringify({
  withdrawAmount: "1000000",
  vault: "vault_address",
  strategy: "strategy_address"
});

// Tool returns JSON response:
{
  status: "success",
  message: "Withdrew 1000000 from strategy successfully",
  transaction: "transaction_signature"
}

​

Example Prompts

For LangChain AI tools, here are example prompts:

​

Position Management

"Get current position values for vault [address]"
"Deposit 1000 USDC into strategy [address]"
"Withdraw 500 SOL from vault strategy"

​

Important Notes

1. Token Programs

   • Supports both Token Program and Token-2022
   • Automatically detects token program type
   • Validates program compatibility

2. Amount Handling

   • All amounts must be in base units (lamports)
   • Use BN.js for precise number handling
   • Consider token decimals when calculating amounts

3. Remaining Accounts

   • Fetched automatically from Voltr API
   • Required for strategy operations
   • Includes instruction discriminators

​

Best Practices

1. Error Handling

   try {
     const signature = await agent.voltrDepositStrategy(
       amount,
       vault,
       strategy
     );
   } catch (error) {
     if (error.message.includes("Invalid asset")) {
       // Handle invalid token program
     } else if (error.message.includes("insufficient")) {
       // Handle insufficient funds
     }
   }
   

2. Amount Calculation

   // Convert from human readable to base units
   function toBaseUnits(amount: number, decimals: number): BN {
     return new BN(amount * Math.pow(10, decimals));
   }
   

3. Transaction Monitoring

   // Monitor transaction status
   const signature = await agent.voltrDepositStrategy(...);
   await agent.connection.confirmTransaction(signature);

Technical Details

​

Constants

const TOKEN_PROGRAMS = {
  LEGACY: TOKEN_PROGRAM_ID,
  TOKEN_2022: TOKEN_2022_PROGRAM_ID
};

​

Voltr Client Configuration

const client = new VoltrClient(connection, wallet);

​

API Endpoints

const VOLTR_API = {
  REMAINING_ACCOUNTS: "https://voltr.xyz/api/remaining-accounts"
};

​

Transaction Options

const TX_OPTIONS = {
  skipPreflight: false,
  preflightCommitment: "confirmed"
};

​

Implementation Examples

1. Full Deposit Flow

   // 1. Get vault account
   const vaultAccount = await client.fetchVaultAccount(vault);
   
   // 2. Verify token program
   const assetTokenProgram = await getTokenProgram(vaultAccount.asset.mint);
   
   // 3. Get remaining accounts
   const { remainingAccounts } = await fetchRemainingAccounts(vault, strategy);
   
   // 4. Create and send transaction
   const ix = await client.createDepositStrategyIx({...});
   const signature = await sendAndConfirmTransaction(tx, [wallet]);
   

2. Position Value Check

   // Get position and total values
   const values = await client.getPositionAndTotalValuesForVault(vault);
   console.log(`Total Value: ${values.totalValue}`);
   values.positions.forEach(pos => {
     console.log(`Strategy ${pos.strategy}: ${pos.value}`);
   });
   

3. Withdrawal with Amount Validation

   // Check available balance before withdrawal
   const position = await client.getPositionValue(vault, strategy);
   if (withdrawAmount.gt(position)) {
     throw new Error("Insufficient balance in strategy");
   }
   const signature = await agent.voltrWithdrawStrategy(...);
