Seed XOR

This splits a mnemonic seed phrase into 2, 3, or 4 parts. It uses the same Seed XOR algorithm as the ColdCard which is deterministic - this means the 1st part is derived from your actual seed phrase, so the same mnemonic will always result in the same parts. ALL parts will be required to re-generate the original seed phrase, so if you lose even just one of them you lose the ability to recover your seed phrase!

If you have an existing seed backup you could use that as the first part - connect the 2nd BIP39 Input box to the 2nd XOR handle to see this and note how the first output now matches it.
