# TransactorAccountShouldBeHotKey (/docs/errors/chain/TransactorAccountShouldBeHotKey)

The extrinsic must be signed by the hotkey itself, but a different account (typically the coldkey) was the origin. Check which key signs the transaction; calls like axon serving expect the hotkey as origin.

Declared by the `SubtensorModule` pallet; it classifies to the semantic code [`not_authorized`](/docs/errors/not-authorized).

## Remediation [#remediation]

Sign with the key or origin that owns the target object, then retry

The same explanation is available in the terminal: `btcli explain TransactorAccountShouldBeHotKey`.
