ColdKeyAlreadyAssociated

Retired error: coldkey swaps into an already-used destination now merge assets into that coldkey. Current runtimes never return this code; if you still see it, you are on a pre-merge runtime — upgrade, or use a destination without staking hotkeys on the older chain.

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

Declared at pallets/subtensor/src/macros/errors.rs#L142.

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 ColdKeyAlreadyAssociated.
