Chain abstraction and paymaster are essential for users to have good underlying technology, and they are prerequisites for the large-scale adoption of blockchain.

The day before yesterday, BNB Chain released an introduction to its roadmap. I won’t summarize the whole article, as it contains a lot of details. I will just pick out two points related to user on-chain interactions to talk about.
There are two points in the original text:
(1) Allow users to pay for gas using stablecoins or other types of BEP-20 tokens
(2) Allowing Gas-free transactions
These two points seem to conflict. I also listened to a BNB Chain Space last night. I heard someone ask about this, but the official didn’t give a clear answer. I will briefly explain how the existing solutions in the market work for these two situations.
