Yes, I can confirm it’s possible to transfer ZEC to a Binance tex address using Zashi.
I don’t think there’s a demo that shows the step-by-step process, but below are a couple resources ECC provided a while back that describe how it works.
Did you shield the ZEC on Zashi or is it held in the t-address you originally transferred it to? I believe you need to shield the ZEC first.
I don’t have a TEX address on Binance to test with myself, so if these resources don’t resolve the issue and you still can’t complete the transfer, let me know and I can connect you with someone who can help.
