I found out recently that BNB Chain also launched their own Layer 2 which is what they call as
opBNB. Basically, it's a scaling solution to the BNB Smart Chain and it also aims to provide users with lower transaction fees and faster confirmation. From my experience, it is indeed cheaper but confirmation is almost the same with BSC (L1). I think this is a good addition to the BNB ecosystem and will probably benefit projects with gaming niche the most.
