currentNullifiers
Lowercase-hex nullifiers of every UTXO currently in this state.
The wallet uses this to prune its durable spent-dust skip-set (drop recorded nullifiers the synced state no longer holds — the event stream caught up) and to detect when all spendable dust is already excluded. A dust nullifier is derived from the secret key, so the seed is required.
Return
the nullifier hex list (empty if the state has no UTXOs), or null if the native call failed. Callers MUST treat null as "unknown" and skip pruning — treating it as empty would wrongly drop the whole skip-set.
Parameters
seed
32-byte dust seed
