# RequireSudo (/docs/errors/chain/RequireSudo)

The call requires the sudo key but was signed by a different account. Compare the sender against the account stored in the Sudo pallet's `Key` storage item.

Declared by the `Sudo` 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 RequireSudo`.
