@ -192,15 +192,6 @@ After receiving this message:
Trezor computes spending keys, `TxinToKey`, `pseudo_out`, HMACs for offloaded data
### `MoneroTransactionInputsPermutationRequest` (Deprecated)
UTXOs have to be sorted by the key image in the valid blockchain transaction.
This message caries permutation on the key images so they are sorted in the desired way.
In Client version 3+ sending the permutation is deprecated. Original sort index is sent from the host
when needed (to verify HMACs built on the original ordering). Moreover, permutation correctness is checked by
the set size, HMAC validity and strict ordering on the key images.
### `MoneroTransactionInputViniRequest`
- Step needed to correctly hash all transaction inputs, in the right order (permutation computed in the previous step).
