I would like to ask the same question.I also want to know how it is being maintained.
Well the Builder platform itself is already live. You can check that out in their site. The price ranges from 3k~80k USD.
But this is still not related to crypto nor related to using the NAYA token, including the escrow payment system.
I agree that Builder is only one part of the puzzle, but more importantly the utilization of the NAYA token, including the escrow payment system are key parts that made us all take a second look at Engineer.ai in the first place.
At some point, they've got to provide us with some information about the ICO TGE launch. Just saying.
Honestly, I can't blame them for not launching yet during this bear market that we have right now. But cheer up guys, the month is almost over and the year is almost over too. For all we know, the ICO TGE details could be disclosed anytime now.
