Skip to main content
Transfer SOL or any SPL token to another wallet address. The function automatically handles both native SOL transfers and SPL token transfers with proper decimal adjustment.

​
Usage

// Transfer SOL
const signature = await agent.methods.transfer(
  new PublicKey("recipient-address"),
  1.5  // amount in SOL
);

// Transfer SPL token
const signature = await agent.methods.transfer(
  new PublicKey("recipient-address"),
  100,  // amount in token units
  new PublicKey("token-mint-address")
);

​
Parameters

ParameterTypeRequiredDescription
toPublicKeyYesRecipient’s wallet address
amountnumberYesAmount to transfer
mintPublicKeyNoToken mint address (omit for SOL)

Example Implementation

Here’s a complete example showing different types of transfers: 
import { SolanaAgentKit } from "solana-agent-kit";
import { PublicKey } from "@solana/web3.js";

async function executeTransfers(agent: SolanaAgentKit) {
  // Transfer SOL
  const solTransfer = await agent.methods.transfer(
    new PublicKey("recipient"),
    1.5  // 1.5 SOL
  );
  console.log("SOL transfer:", solTransfer);

  // Transfer USDC
  const usdcTransfer = await agent.methods.transfer(
    new PublicKey("recipient"),
    100,  // 100 USDC
    new PublicKey("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v")
  );
  console.log("USDC transfer:", usdcTransfer);
}

​
Implementation Details

  • Automatically detects SOL vs SPL token transfers
  • Handles decimal adjustment for SPL tokens
  • Creates Associated Token Accounts if needed
  • Uses single-instruction transactions for efficiency

​
Error Handling

try {
  const signature = await agent.methods.transfer(recipient, amount, mint);
} catch (error) {
  if (error.message.includes("insufficient funds")) {
    // Handle insufficient balance
  } else if (error.message.includes("invalid account")) {
    // Handle invalid addresses
  }
}

​
Best Practices

  1. Amount Validation
    • Always verify token decimals
    • Check balances before transfer
    • Account for transaction fees
  2. Address Validation
    • Validate recipient addresses
    • Double-check mint addresses
    • Use address checksums
  3. Transaction Management
    • Monitor transaction status
    • Implement retry logic
    • Handle timeouts appropriately
  4. Security
    • Verify recipient addresses carefully
    • Implement confirmation dialogs
    • Consider using transaction previews
