Seed scheme
Feather uses the monero-seed library written by Tevador, for 14 word mnemonic seeds.
The discussion that lead to its creation can be found here.
Feather can restore wallets from both 14 word and 25 word seeds.
This seed scheme has a number of advantages over Monero core’s seed scheme:
- The wallet creation date is embedded in the mnemonic seed. This way you no longer have to worry about restoring your wallet from the correct restore height.
- It uses BIP-39 wordlists. These wordlists container shorter and more common words than Monero’s lists.
- 14 word seeds are quicker to write down and memorize.

Convert 14-word seed into 25-word seed
Go to Wallet → Seed, enter your password, and check Show 25 word seed. Make sure to also note the restore height to make restoring the wallet faster.
Convert 25-word seed into 14-word seed
This is not possible. The 14-word seed scheme uses a KDF to derive the actual spendkey, this operation is non-reversible.
Second seed word is always “poet”, is this a bug?
No. In addition to the private spend key, Tevador’s seed scheme also encodes the restore date, cryptocurrency type, and reserves a few bits for future use. The second word is static because some of the reserved bits remain the same for each seed generation.
