What the explorer knows about an address: LAX balance (wei and LAX), whether it is a contract and verified, its name and public tags, whether the explorer flags it as a scam, proxy implementations, the creator and creation transaction of a contract, token metadata if it is a token, and counters: transactions, token transfers, gas used and blocks mined. Names, symbols, tags and method names are set by whoever deployed or verified a contract and are wrapped as untrusted.
