I would like to get all ERC20 token smart contract bytecodes in Ethereum network.
Is there a way to scan the blockchain for ERC20 smart contracts and/or scan an address for a [ERC20] smart contract?
Have a look at EIP165. It allows you some form of introspection wether an address offers a certain interface. Obviously this only works for contracts that at least implement ERC20 and EIP165.
How to detect if a contract implements ERC-165:
If the call returns true, a second call is made with input data 0x01ffc9a7ffffffff00000000000000000000000000000000000000000000000000000000.
If the second call fails or returns true, the destination contract does not implement ERC-165. Otherwise it implements ERC-165.
How to detect if a contract implements any given interface:
