I can feel your pain.
Stellar Bifrost looks good on paper but it will never get mass adaption because it's a small community and the support is pretty lame.
Only a handful companies managed to get BiFrost working and they won't share how they did it. You see that's the problem.
I've also been struggling with BiForst for a couple of weeks and decided to switch to Ethereum. Their community is very big and with good support. On YouTube you can find tons of video-tutorials for setting up ERC-20 Ethereum and complicated time-locked contracts. Is there a videotutorial of BiFrost on YouTube? No...vAs I've wasted so much time with BiFrost I've decided to hire an Ethereum developer....Within one day (!) I've found one who even developed customized time locked contracts the same day (!). Try that in this community. I see you've been communicating here a couple of days. Have you found a developer? No? Waste no more time just switch!
Again, Stellar BiFrost looks good on paper but their support should be way better in order to get mass adaption. Unfortunately it won't change unless this community begins to realize that things have to change right away. Good luck!
