Bitcoin Forum

Found a stack of wallets from 2014, but I have no idea what coins they relate to (the fact that they aren't labelled probably means they are garbage though). Any painless ways of identifying these crypto's from the wallet.dat files alone? 

Surely someone has resolved this issue before.

I personally cannot help because I lack the necessary knowledge, but this may help you out: https://bitcoin.stackexchange.com/questions/19589/how-to-determine-what-type-of-coins-a-wallet-dat-contains

I believe you need Linux to run pywallet though. I'd rather run it on an offline Live Linux CD to minimize risks.

I know next to nothing about python, but I'll give it a go (cheers). I started putting these wallets into various blockchains but kept getting '0/unconfirmed, not in memory pool' for the receiving transactions and the transaction ID is invalid. I got excited when I saw 1690 in Dash only to have my hopes dashed later.

Hey, try moving your topic to Development & Technical Discussion section (https://bitcointalk.org/index.php?board=6.0), maybe you can get some help there.

If i remember correctly, you should be able to open it with a text editor and spot the coin TICKER.
But i might be mistaken, it's been 5 years since i touched a local wallet

I just tried that with a Bitcoin wallet.dat file and was unable to locate the ticker BTC. Good shout though (it did look promising).

It will work for wallet.dat which is unencrypted you can just open it with notepad or notepad++ and you will see all inside the wallet.dat including a public key and private keys.

But if it's encrypted there's no way to see them with any text editor.

Can you check this one below and maybe it will work you will need a Linux Based OS.

- What alt-coins do they have (and may be how much)? (https://bitcoin.stackexchange.com/questions/57122/have-a-bunch-of-wallet-dat-files-what-alt-coins-do-they-have-and-may-be-how-mu)

Once you get the addresses you can paste one of the addresses extracted from the wallet.dat here and let us find it for you.
If the prefix of the wallet address looks the same as 1 or 3 at the beginning of the address then it is a bitcoin wallet but if it shows different prefix you might need to refer on this prefix list below.

- Altcoin Prefixes (https://github.com/ethernomad/coins/blob/master/coins.yaml)

This is not a complete list but if you can post the address maybe we can determine which altcoin that this wallet.dat belongs.

You simply open them with notepad and search for the string "name"

If the following string starts with 1 and looks like this

1CC3X2gu58d6wXUWMffpuzN9JAfTUWu4Kj

 its a bitcoin. If the first character starts with  L for Litecoin etc. As long as they have transactions. If there is no "name" string then they are most probably empty

For a list of altcoin names you can search the web

Thanks for the help guys, however I managed to accumulate a steaming pile of crap; Execoin, Hirocoin, Megacoin, Heavycoin, Franko, Maxcoin, Riecoin, Bytecoin, Potcoin, Counterparty, Blackcoin, Vertcoin (OK I guess, but overall still equals a loss on initial investment). I remember being keen on privacy coins, therefore not sure how I missed Darkcoin (remember buying it, therefore must have sold or lost on an exchange failure like Mintpal  :'( ) or Monero.

I could try to help you if you still need to solve it

On Mac/Linux you can use the `strings` command to get all ASCII strings out of a binary file. You can then use grep to see if any of the strings match a given coin. For example:


Or you could save the strings output to a txt file and inspect it with a text editor:
