This simple program demonstrates how to use the SPL Token Program to mint new tokens.

Conclusion

In this tutorial, we explored how to track a specific Solana address for new trades using the Solana Web3.js library. By monitoring transactions and parsing their instructions, we can log details of each new trade to the console. This approach can be extended to trigger notifications or other actions when new trades occur.

You can run this script periodically to monitor for new token creation events. Consider setting up a cron job or a scheduled task to execute the script at regular intervals.
