I have a python library to create wallets and play around with private key generation and stuff like that.
But i can't find any service / wallet - preferably online - where i could import my generated testnet-private-key and check the balance...
I can get coins thru Testnet Faucet and see the balance of an address on testnet via Blockcypher but where can i test importing private keys on the testnet?
EDIT: I don't really want to download the whole blockchain so some online service would really be great!
