Rate Limits Checker

A simple script to query and display rate limit values from the Bittensor network.

What it does​

Connects to the Bittensor Finney network and queries:

  • Global rate limits: Transaction limits, delegate take limits, network limits, etc.
  • Subnet-specific limits: Serving rates, adjustment intervals, immunity periods, etc.

Prerequisites​

  • Node.js 18.0 or higher
  • Dependencies installed (run yarn install if needed)

How to run​

yarn node docs/scripts/check-rate-limits.js

Note: This project uses Yarn PnP, so you must run the script with yarn node instead of just node.

Troubleshooting​

Error: Cannot find module '@polkadot/api'

  • Make sure you've run yarn install first
  • Use yarn node instead of node to run the script

Connection timeout
