SVM Gas Sponsorship is Dynamic’s built-in feature that automatically sponsors Solana (SVM) transaction fees for embedded wallet users.
SVM Gas Sponsorship is available exclusively for V3 MPC embedded wallets. It works automatically once enabled - no code changes required.

​
Overview

When enabled in your dashboard, the SDK automatically:
  1. Intercepts transactions before signing
  2. Sends them to Dynamic’s backend for sponsorship
  3. Returns a sponsored transaction with Dynamic as the fee payer
  4. User signs the sponsored transaction
  5. Transaction is broadcast to the network

​
Enabling SVM Gas Sponsorship

  1. Go to the Dynamic Dashboard
  2. Navigate to Settings > Embedded Wallets
  3. Ensure Solana (SOL) is enabled in your chain configurations
  4. Toggle on SVM Gas Sponsorship

​
Usage

Once enabled, transactions are automatically sponsored. No code changes needed: 
import { signAndSendTransaction } from '@dynamic-labs-sdk/solana';

// Transaction is automatically sponsored if feature is enabled
const sendTransaction = async (walletAccount, transaction) => {
  const { signature } = await signAndSendTransaction({
    transaction,
    walletAccount
  });
  console.log('Transaction sent successfully.', signature);
};

​
Checking Sponsorship Status

import { getDynamicClient } from '@dynamic-labs-sdk/core';

const client = getDynamicClient();
const settings = client.getProjectSettings();
const sponsorshipEnabled = settings?.sdk?.embeddedWallets?.svmGasSponsorshipEnabled ?? false;

console.log('SVM Gas Sponsorship:', sponsorshipEnabled ? 'Enabled' : 'Disabled');

​
Limitations

LimitationDetails
Wallet typeEmbedded wallets only (V3 MPC)
Transaction sizeMaximum 2KB base64-encoded
Already-signedTransactions with signatures are not sponsored
BatchingEach transaction sponsored individually

​
Fallback Behavior

If sponsorship fails, the SDK falls back to the original transaction. Users will need SOL for gas fees in this case.

​
Error Handling

import { signAndSendTransaction } from '@dynamic-labs-sdk/solana';

const sendTransactionWithFallback = async (walletAccount, transaction) => {
  try {
    const { signature } = await signAndSendTransaction({
      transaction,
      walletAccount
    });
    return { success: true, signature };
  } catch (error) {
    const errorMessage = error.message?.toLowerCase() || '';

    if (errorMessage.includes('insufficient')) {
      return {
        success: false,
        error: 'Insufficient balance for transaction'
      };
    } else if (errorMessage.includes('sponsor')) {
      return {
        success: false,
        error: 'Gas sponsorship failed, SOL required for fees'
      };
    }

    return { success: false, error: error.message };
  }
};
