zair key

Key derivation utilities for the airdrop proving pipeline.

zair key derive-seed

Derives a 64-byte BIP-39 seed from a mnemonic and writes it as 128 hex characters to a file.

zair key derive-seed --mnemonic-file mnemonic.txt --no-passphrase --output seed.txt

zair key derive-ufvk

Derives a Unified Full Viewing Key (UFVK) from a seed file or mnemonic. The UFVK is mostly useful for claim prepare to scan for eligible notes without requiring spending authority. This would allow a user to outsource the claim preparation to a party who only holds the viewing key, not spend-keys.

zair key derive-ufvk --seed seed.txt --network testnet --output ufvk.txt

Exactly one of --seed, --mnemonic-file, or --mnemonic-stdin must be provided.

Note

The --account index must match the account used later in claim prove and claim sign.
