Not many exchanges out there has the erc20/ bep20 bridges
for instant, and it is a big challenge to smaller investors. Exchange like Binance has been able to integrate this bridges between erc20 and bep 20 token, trc20. I hope that this upgrade should carried out on other exchanges, especially the Dex exchange to reduce the huge high transaction fees on the erc20 tokens.
Besides, this upgrade, that is, from erc20 bridges to other networks like Bep20, trc20 etc, there may not be other short cut or mean to escape the erc20 tokens high gas fees. However, I think that with launch of the Ethereum 2.0, we may has a solution to the current gas fees.
