So, the question is, does actually exist a program that can wrap a token present on the BSC to make it run on the Ethereum chain (to make it simple, a BSC ---> ETH-chain wrap)?
It doesn't exist. As far as i know that you can create yourself but the problem is if you must also create a bridge for your token and then you can try to create two contracts, 1 for ethereum and 1 for BSC.
Because I only find programs that do the opposite thing, wrap an Ethereum based token in order to make it fit on the BSC, for example, the wrapper present on TomoChain.
it seems like that is the only way to fork the bridging code and then create your own bridge. I have rarely seen such service in BSC chain. The only problem, if it's, must integrate both of your contracts to be able to bridge your assets from both of chains. Is not it better for you to get service from freelance developers to create a bridge for you?
