I have a question for you all. What happens to all the tokens mistakenly sent from a wallet to a wrong wallet and where do they go?
You aren't specific and clear at your question. Please mention what does you mean. Is that the same coin's address or totally new coin's address. If it's the same coin like you have mistakenly sent bitcoin to another bitcoin address, coin will be lost. There's no way of recovering those. If that address exist, he will be the owner. On the other hand, there will be nothing lost if you send in another coin's address.
If it means exactly what he says, then it just means the coins stay in those addresses.
You cannot mistakenly send to an address that the format is not recognized. The transaction simply will be considered by nodes to be invalid.
If the spent is successful, the new input is in the new wallet, whoever controls the private key owns it. That is all.
