ColdkeySwapDestinationReserved

This account is reserved as the destination of an in-flight coldkey-swap announcement, so it cannot be registered as a hotkey and another coldkey cannot announce to it until that announcement is executed, cleared, released by the destination, reset by root, or the reservation TTL expires. Wait for the reservation to clear, have the destination call release_own_coldkey_swap_destination_reservation, or choose a different account.

Declared by the SubtensorModule pallet; it classifies to the semantic code already_exists.

Declared at pallets/subtensor/src/macros/errors.rs#L463.

Remediation

The object or state already exists; treat the goal as met or pick a different target

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