Binance aquired a few infrastructure companies like CMC.

They also run and ran many of the instant swap CEX.

After having had a closer look, the Binance offer for Travala didn't go through. So more correct would be Travala being a Binance front with close cooperation and indirect ties. Maybe one can find something if looking closer. WazirX was/is also a Binance owned/connected CEX but claims around ownership were always conflicting. It seems that Binance prefers to pull strings from behind.
