Ondo Global Markets offers tokenized versions of publicly-traded stocks and ETFs on Solana. These tokens (such as NVDAon for Nvidia, TSLAon for Tesla, and SPYon for S&P 500) can be swapped on decentralized exchanges via Jupiter, making them accessible to both human users and AI agents through Crossmint wallets. This guide demonstrates how to swap USDC for Ondo GM tokens using the Jupiter swap API with Crossmint wallets on Solana.

​
Prerequisites

  • A Crossmint wallet on Solana with USDC balance. See the wallets quickstart to create one.
  • API Key: A server-side API key (sk_...) with the scope wallets:transactions.create.
  • The Solana mint address for your target Ondo token. Find all available Ondo tokens and their liquidity on the Jupiter Ondo screener.

Swap USDC for Ondo Tokens

The swap flow uses the same pattern as any Jupiter swap with Crossmint wallets:
  1. Request a quote from the Jupiter API for the USDC to Ondo token pair.
  2. Build the swap transaction using the Jupiter API.
  3. Sign and send the transaction using the Crossmint wallet.
Ondo GM tokens on Jupiter may route through multiple AMM pools (such as Manifest, Meteora DLMM, or Raydium CLMM). Always set maxAccounts=33 to ensure multi-hop swaps fit within Solana transaction account limits.

            Buffer.from(swapData.swapTransaction, "base64")
        );

        const tx = await solanaWallet.sendTransaction({
            transaction: versionedTransaction,
        });

        console.log("Swap complete:", tx.hash);
    }

    return (
        <button onClick={() => swapUsdcToOndo(NVDA_ON_MINT, 1000000)}>
            Swap 1 USDC for NVDAon
