EOA and contract accounts have a different code size then you can use It to determinand if an address is a EOA or contract account but you will need use the assembly inline: function isContract(address addr) returns (bool) { uint size; assembly { size := extcodesize(addr) } return size > 0; }

Tx you can do by number of bytes. There’s a function in openzeppelin’s address library (isContract) to determine which of the other two it is - https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/utils/Address.sol
