Using Custom Gas Vaults in Gas Station – Auto-Fuel Issue & Tron Support

Developer Discussion
1

Hi Fireblocks team & community,

I’m currently testing in Sandbox using the account registered under:
dung.nguyen.trung+1@cozuchi.com

I ran into a few issues and questions:

1. Auto-Fuel Not Working with Custom Gas Vaults

I created 3 separate vaults specifically for gas fees and replaced all addresses in the Gas Station setting with these custom vaults (instead of the default gas station addresses).

After this change, the Auto-Fuel feature stopped working.
Previously, it worked fine when I used the default gas station addresses provided by Fireblocks.

:red_question_mark:Question:
Am I allowed to use my own custom vaults as Gas Station wallets in both Sandbox and Production?
If yes, what is the correct procedure to make Auto-Fuel work with them?

2. Tron Support in Gas Station

I noticed that in the default gas station settings, Tron is not listed.

:red_question_mark:Question:
Does Production currently support Tron for gas station auto-fueling?
If not, is it planned or is there any alternative workaround?

Thanks in advance for the support!
