Floor on delegate fees.
Current Value
0Relevant for: validatorsdelegatorsstakers
The Big Picture
Functionally similar to InitialMinTake - the floor on delegate commission. This prevents validators from undercutting each other to zero, ensuring all validators earn minimum revenue for their service. It maintains validator economics and network quality.
Why This Matters
You cannot set your take below this floor. Plan your competitive strategy knowing this is the lowest possible rate - you'll compete on performance and reliability instead.
Example
With MinDelegateTake of 900 (9%), the most delegator-friendly rate is 9%. All validators compete above this floor. Delegators shopping for lowest fees know 9% is the floor.
Common Questions
- Why not allow 0% take?
- Zero take isn't sustainable - validators need revenue. The floor ensures validators can cover costs and invest in infrastructure quality.
- Do all delegates charge the minimum?
- No, many charge more. Lower isn't always better - delegators often prefer higher-take validators with better performance or reputation.
