I have sent you a private memo containing the project link. Please review the page and instructions and run some test transfers (for example sending 1 coin to a few people in a batch) to ensure it works as expected. The batch method does require your key, so creating a separate "transfers" HIVE account may be useful.
The link sent includes the ability to send Hive-Engine/TribalDex second layer tokens (coins) to multiple users via batch processing. It does have some setup/instructions that need to be followed, and additionally proper care should be taken to confirm usernames and amounts before the batches are sent to prevent unwanted interactions, and in addition to confirm that each transfer successfully occurred.
If you have questions or concerns please let me know.
