title: Is there any way to get the address of the library for a specific contract address?
body: <p>We have a smart contract factory, which deploys smart contract instances.</p>
  
  <p>These smart contract instances use SafeMath.</p>
  
  <p>We want verify code for these instance on Etherscan.</p>
  
  <p>But, Etherscan requires SafeMath library address to verify contract code.</p>
  
  <p>Question is how to get SafeMath library address for each instance.</p>
