List imported watch-only adresses I can import addresses without private key just to track incoming transactions as it is provided in RPC calls :
https://bitcoin.org/en/release/v0.10.0#watch-only-wallet-support

But how can i see my previously imported addresses? (With or without RPC)

Bonus : Is there any proper way to delete them?
OK. I've found a workaround by adding label on importing :

bitcoin-cli importaddress &lt;address&gt; my_imported_address_list


Checking my label on listing :

bitcoin-cli getaddressesbyaccount "my_imported_address_list"


This solves my problem for now. But still searching for better answer where i dont need to label my own imported addresses.
