# AnnouncedColdkeyHashDoesNotMatch (/docs/errors/chain/AnnouncedColdkeyHashDoesNotMatch)

The `new_coldkey` passed to `coldkey_swap` hashes to a different value than the hash committed in the earlier `announce_coldkey_swap`. Verify the announced hash in the `ColdkeySwapAnnouncements` storage matches the BlakeTwo256 hash of the coldkey you are swapping to.

Declared by the `SubtensorModule` pallet; it classifies to the semantic code [`invalid_argument`](/docs/errors/invalid-argument).
