This call is no longer available in the current runtime. Existed from v156 to v160. Shown here for historical reference.

Likely renamed to schedule_coldkey_swap (same index 72) in v161 — name matching breaks, index matching is unaffected.

Migration Notes

v157 v158 Breaking

removed field hotkey (was AccountId)

Update decoders: SCALE encoding is positional, so any signature change (added, removed, or type-changed fields, or storage shape changes) shifts byte offsets and existing decoders will misparse this item. Re-derive types from the new metadata.

Input Parameters
