A chain is a shared ledger

A blockchain records state: who owns a token, which contract holds liquidity, and which transactions changed those balances. Wallet interfaces are ways to read that state and submit requests to change it. They are not the ledger itself.

BNB Smart Chain is an EVM network. Its mainnet chain ID is 56 and transaction gas is paid in BNB. The same hexadecimal wallet address can exist on several networks, but its balances are different on each one. Always check both the address and the selected network.
