HotKeyAlreadyDelegate
Error v151 → v212, v216 → v219, v233 → v315, v320 → v393, v401 → current 7.28This hotkey is already registered as a delegate.
Why This Error Exists
Becoming a delegate is a one-time action that enables your hotkey to receive stake from other coldkeys. Once you're a delegate, others can stake to your hotkey and earn a share of your rewards (minus your take). This error simply means your hotkey is already set up to accept delegations - you can proceed with other operations.
Deep Dive
The Delegates storage maps hotkey -> bool. When become_delegate is called, it sets this to true and initializes your delegate take (the percentage of delegator rewards you keep). The take defaults to a standard rate but can be adjusted with increase_take or decrease_take. Trying to become a delegate twice is harmless but redundant.
Debugging Example
You call become_delegate(hotkey=5Xyz...). Error: HotKeyAlreadyDelegate. Query Delegates(5Xyz...) - returns true. Your hotkey is already a delegate! This is actually good news. Query DelegateTake(5Xyz...) to see your current take rate, then proceed with operations.
Prevention Tips
- Query Delegates(hotkey) before calling become_delegate
- If it returns true, skip the become_delegate call
- Handle this error as a success case in automation scripts
From Chain Metadata
The hotkey is attempting to become a delegate when the hotkey is already a delegate.
What This Means
This hotkey is already registered as a delegate.
Common Causes
- Called become_delegate on an already-delegate hotkey
- Previous delegate registration succeeded
How to Fix
- Check SubtensorModule.Delegates to verify delegate status
- If already a delegate, proceed with other operations
- Use increase_take or decrease_take to modify existing delegate
