I have list of addresses & I am trying to find out if the address is wallet address or smart contract address. I am using web3js. Is there any way to distinguish between smart contract and wallet address?

As an example, let's say I have an address x = "0x0f3dd2fcd9ff5b8b082db6e39a1b11a579cfdee5" and I need to know if x is a smart contract or wallet.

thank you very much.

A smart contract address is an ethereum address that has code/data behind it. so to check if the given address is "currently" a contract you can use the getCode method from Web3js

web3.eth.getCode(address [, defaultBlock] [, callback])

If this method returns something then it is 100% a contract, otherwise it is an address of a wallet or a contract that has not been deployed yet (or already self destructed)

    GetCode returns empty for self-destructed contracts.
