Hello fellow bitcoiners,

Is there a utility available to combine multiple wallet.dat files into one? I've kept a couple different wallets up till now but would like to combine them into one.

Thanks,
gigavps

You could sequentially load each wallet and send all the coins to a brand new wallet, consolidating all your funds.

Export the private keys of each wallet and import them all into the new one.

This is probably what the Pywallet reply is about, but there are other ways. Bitcoind itself has the "dumpprivkey" and "importprivkey" commands. I use my Python script to do this.

Exporting and importing keys has some definite advantages compared to sending coins the usual way:

  • No transaction fees
  • Keep receiving addresses alive

Treat your coins with respect. Only "pump and dump" people.

  • Keep receiving addresses alive

This is really the most important thing to me. I'll definitely be diving into this next week to get the wallet.dat files consolidated.
