Why Nominator Stability Matters

Direct Impact on Your Position: Unstable nominators are more likely to switch validators, which can cause sudden drops in your backing and potentially push you out of the active set.

Health Score: Contributes 10 points to your overall health score under "Nominator Quality" dimension.

Current Risk Level

Moderate Risk: Your nominator base has moderate stability. While 156 nominators have been with you long-term, 115 are relatively new (<90 days). Focus on building relationships with your newer nominators to improve retention.

How to Improve Nominator Stability

Build trust through consistency: Maintain high uptime, consistent era points, and stable commission rates
Engage with your community: Active presence on social media, Discord, or Telegram shows nominators you're committed
Demonstrate transparency: Share your infrastructure details, location, and operational practices
Optimize performance metrics: Higher era points and better grades attract quality, long-term nominators
Competitive but stable commission: Avoid frequent commission changes that can scare away nominators

Impact Assessment:

Recent Nominator Behavior

Stake from Recent Switchers 42.1%

What This Means:

High Turnover - Large portion of stake from recent switchers. These nominators have shown they're willing to change validators and may leave again

How to Reduce Risk

Diversify your nominator base: Attract more nominators to reduce dependency on your largest backer (currently 38.5%)
Build nominator loyalty: Engage with your community, maintain consistent performance, and communicate openly
Monitor slot position: Keep track of your active set buffer - aim for 200+ slot cushion for safety
Improve performance metrics: Higher era points and better uptime attract stable, long-term nominators
Set competitive commission: Balance rewards to attract nominators without sacrificing your validator income
URGENT: Your buffer is critically low. Focus on attracting new nominators immediately
