Explore chainQueried by: validatorsdevelopers
The Big Picture
Hotkey swaps on subnets are rate-limited. This tracks when the last swap occurred, enabling cooldown calculations and preventing spam swaps.
Use Cases
- Check swap cooldowns
- Plan hotkey operations
- Debug rate limit errors
From Chain Metadata
DMap ( netuid, coldkey ) --> blocknumber | last hotkey swap on network.
Purpose & Usage
Purpose
Track hotkey swap timing for rate limiting.
