Title: testnet paper wallet Post by: mocacinno on February 21, 2016, 09:23:02 AM Just a quick question: i'm thinking about creating a couple paper wallets to store some of my funds onto.
To learn a bit about the process, i created a testnet paper wallet (bip38 encrypted) using this site: https://bitcoinpaperwallet.com/bitcoinpaperwallet/generate-wallet.html?design=alt-testnet# I went to a couple of testnet faucets, and loaded the address with some funds: http://tbtc.blockr.io/address/info/n3JAFRQHqzBDiQckSxp8xQ2hyBtk1jVZoh The address should currently hold 15.06 tBTC Afterwards, i downloaded greenbits and shildenbach's client for the test network on my android mobile, and tried to sweep the wallet. The process itself works (i mean, the android wallet does ask for a passphrase), but after that: it says the address holds 0 tBTC. I've tried using the website above https://bitcoinpaperwallet.com/bitcoinpaperwallet/generate-wallet.html?design=alt-testnet# to decrypt the bip38 encoded private key, and it seems to generate a valid private key, and the correct public key (the one that does hold +15tBTC), so i'm a bit lost at this point. I tried to sweep the unencrypted private key, but the aindroid wallet still says the address holds no funds :( I ran the bitcoin-qt with the -testnet option, but i got a bit frustrated when i saw how many blocks the testnet chain had, and since my HD is almost full i had to stop the synchronisation... Is there someone who knows what's happening, or somebody that has bitcoin-qt testnet sync'd, and is willing to import my private key to see of the coins are at least at the correct place?

You absolutely need to sync everything with bitcoind. As for your mobile wallets, maybe they have trouble finding peers (which wouldn't surprise me since it's testnet).

As for your mobile wallets, maybe they have trouble finding peers (which wouldn't surprise me since it's testnet). thanks :) importing the private key does indeed give me the correct public address, and using a testnet block explorer, i can see that this public address has indeed funds... So chances are indeed large that i'm missing some peers or that i'm not correctly synced. EDIT: - i installed bitcoind on one of my servers and ran bitcoind -testnet - i used https://bitcoinpaperwallet.com/bitcoinpaperwallet/generate-wallet.html?design=alt-testnet# (validate or decrypt) to decrypt my bip38 encrypted private key - then bitcoin-cli -testnet importprivkey mydecryptedkey - then i waited a couple of hours for the synchronisation to happen - my coins showed up ;D However, i did not manage to sweep the paper wallet with shildenbach's android wallet, mycelium testnet wallet, greenbit testnet wallet,... I've tried almost all testnet wallets in the android store, none of them wanted to sweep my paper wallet :( Hope my real paper wallet will work fine... I'm thinking about creating a paper wallet and transferring 0.005BTC to it, then sweep it, then burn it... Afterwards i'll download the sourcecode of https://bitcoinpaperwallet.com/bitcoinpaperwallet/generate-wallet.html, turn off my internet, generate a wallet offline, print to a pdf on an usbstick, print from the usb stick, scratch the usbstick, reboot my pc and put a chunk of my funds on the paper wallet |
