Cryptoctopus patiently waits until you
copy a Bitcoin or Ethereum address (or
transaction hash) into clipboard.
Cryptoctopus asks open APIs
(such as Etherscan and Blockchain.info)
for the latest relevant information about that address and shows it to you.
It's Open Source (see GitHub) so you can be
sure that your secrets remain yours!
If you ever encounter that address or transaction
hash again - Cryptoctopus will remind you and
show your label and notes together with important highlights. You may also search
that database at any time or set alert conditions for any address.
