<p>I have the 12 key seed phrase from a 10 year old Bitcoin-qt acct, but don't know what tool to use to turn it into a wallet. Obviously I am terrified to put the seed phrase into any ONLINE tool. I want to practice offline somehow to see if I even wrote it down properly. I tried looking thru the sourcecode: <a href="https://github.com/bitcoin/bitcoin" rel="nofollow noreferrer">https://github.com/bitcoin/bitcoin</a> to see there is a word-list.. No joy.  One guy said Electrum, but it didn't help decipher the individual words, just kind of a 'put them all in', sink or swim endeavor....</p>

bitcoin-qt has never supported the 12 words seed phrase, so has to be another wallet.

The most common English word-list for seed-phrases (AKA backup-phrases, recovery-phrases) is probably the [BIP39 word list](https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt) but early versions of Electrum [were different](https://electrum.readthedocs.io/en/latest/seedphrase.html)

seems also that seed can't be 10 year old, since Electrum introduced it in 2015.
