AccountRejectsLockedAlpha

Locked alpha was being transferred to a coldkey whose AccountFlags do not have the accept-locked-alpha bit set, e.g. during a lock transfer or coldkey swap of locks. Check the destination coldkey's AccountFlags storage and have the recipient opt in to receiving locked alpha before retrying.

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

Declared at pallets/subtensor/src/macros/errors.rs#L330.

Remediation

The destination coldkey rejects locked alpha; they must opt in, or send unlocked stake only

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