Check if an address is a EOA or contract

I am trying to determine wether or not an address I pull from the request objects is a smart contract or an externally owned address. I came up with this function which seems to work but somehow it is not always correct.

Moralis.Cloud.define("isContract", async request => {
  if (!request.params.address) return;
  try {
    const result = await web3.eth.getCode(request.params.address);
    if (result !== "0x") {
      return true;
    }
    return false;
  } catch (error) {
    logger.info("Error: " + error);
  }
});

For example when I feed this function with the address 0x64a078926ad9f9e88016c199017aea196e3899e1

it returns this value

0x608060405234801561001057600080fd5b5060043610610…

which according to my function above should return “true” but it is saved in my database as false. Anyone sees where Im going wrong here?

the logic from this function seems ok to me

#3

I agree on that. Confusing to me why I have values of “false” in my EthTokenTransfers table when from- or to_address returned “true” by this function.

Can you log inside if (result !== "0x") { for this particular address? Just to make sure it’s executing that block as it should.
