I was looking at some of the top 50 stablecoins ,and im thinking Polkadot. Apart from erc and bep tokens
Stablecoins? I'm ot sure dot is a stablecoin, but it's one of the top coin right now and it's kinda hot compared to old era tokens of eos and neo. There are plenty of chains that you could try aside from erc20 and bep20, there are ftm tokens and avalanche tokens, they are also same with those you mentioned with a different usage of chain. Some much faster and lower in transactions fee.
