Your stake is below the minimum required to participate in the root network (netuid 0).

Encountered by: validatorssubnet ownersstakers

Why This Error Exists

The root network (netuid 0) is special - it's where subnet validators vote on emissions allocation across all subnets. Because of its importance, there's a minimum stake requirement to participate. This ensures only serious, economically-aligned participants influence network-wide emissions.

Deep Dive

MinStakeForRoot is a governance parameter that can change. Currently it's typically around 1000+ TAO. This check applies when: 1) Registering on root network, 2) Setting weights on root, 3) Unstaking if you're registered on root. The stake counted is TotalHotkeyStake - your hotkey's total stake from all delegators.

Debugging Example

You try to register on root (netuid=0) with a hotkey that has 500 TAO stake. Error: StakeTooLowForRoot. Query MinStakeForRoot - returns 1000 TAO. You need 1000 minimum, have 500. Solution: Stake 500+ more TAO to your hotkey, then retry root registration.

Prevention Tips

Check MinStakeForRoot before attempting root network operations
When unstaking, calculate if remaining stake stays above root minimum
Monitor governance proposals that might change the minimum requirement

From Chain Metadata

A hotkey with too little stake is attempting to join the root subnet.

What This Means

Your stake is below the minimum required to participate in the root network (netuid 0).

Common Causes

Trying to register on root with insufficient stake
Unstaking would drop you below root minimum
Root network has higher stake requirements

How to Fix

Check SubtensorModule.MinStakeForRoot for current minimum
Increase your stake to meet root requirements
If unstaking, leave enough to stay above minimum
