I am trying to develop some application using bitcoin (currently only in the regtest mode). I am aware that one can create a new address using

bitcoin-cli -regtest getnewaddress

RPC call, but I want to know whether bitcoind pre-generates a bitcoin wallet address when we install and run

bitcoind -regtest -daemon

fresh. If yes, how can I know this address?

No.

The wallet actually always pregenerates keys (not addresses) and puts them in the keypool. A keys is fetched from the keypool and converted to an address only when an address is explicitly requested (via getnewaddress or from the GUI). An address is not pre-fetched by default.

  • Thank you Andrew. Where can I find these pre-generated keys?

  • You can't without using getnewaddress. They are not shown to users as keys by themselves are not particularly useful.
