thank guys
i have understood it , same address for eth chain and bsc chain
and i would get all the coins with one address only
Not just bsc and eth. All other network could also be added with using your single address like avalanche, polygon, fantom, and many more. Thats how metamask is useful on those networks sincr you play only one single address for those L1 projects. Im not sure if solana and terra can be added but I think they havent supported on adding network. But not totally sure.
