I created a contract.

https://ropsten.etherscan.io/tx/0x74426948905cd6e70e8b9d64a660b3c179b7c8a224ca5cd0234842768eb501db

The contract hash is 0x692a70d2e424a56d2c6c27aa97d1a86395877b3a

etherscan shows the contract has many transactions. The latest three transactions are mine. But the other txes are sent by someone.

My contract was copied and pasted from tutorial page. I think this is the cause since data is same. Is this my understanding correct?

pragma solidity ^0.4.0;
contract Addition {
  int num = 0;
  function add(int a){
    num += a;
  }
  function get() returns(int){
    return num;
  }
}

The contract address is unique for each deployment. You (or anyone else) can't create a different or same contract with the same address.

That people have transacted with your contract doesn't mean anything in this instance.

  • Thank you. My contract transaction was wrong. I put wrong data into "to" param when I sent raw transaction. – zono Jul 17 '17 at 14:19
