How does the truffle migration of this contract know what the address is of the registry contract, in the constructor:


If the registry was deployed to Ethereum after the Token?

Registry creation: https://etherscan.io/tx/0xe8193e2f72d00d086c3876e8ae84f529848e1c730501158f1ff837426d99f4f1

Token creation: https://etherscan.io/tx/0x0d5d5506aed5a615986dc92f9d982c7e0f19c96e31e8488ea15d4f8046252983

Sorry if I am being silly.

Managed to get an answer from the developer of the project.

In case anyone else finds themselves here:

Contract addresses are deterministic (a combination of deployment account/address and the nonce). They have a utility function here called getAddress which is able to determine what the contract address will be:


  • Address of the deploying account would be more accurate. May 23, 2019 at 6:31
  • Thanks @goodvibration, made an edit. :)
