The Big Picture
General rate limit for certain transactions. Prevents spam and ensures fair access to block space.
Use Cases
- Understand transaction limits
- Plan transaction batching
- Build rate-aware tools
From Chain Metadata
ITEM ( tx_rate_limit )
Purpose & Usage
Purpose
Control transaction frequency network-wide.
Common Query Patterns
- Single value query
Stored Value
Code Examples
import { createClient, Binary } from "polkadot-api";
import { getWsProvider } from "polkadot-api/ws";
import { sub } from "@polkadot-api/descriptors"; // generated by: npx papi add sub -w wss://entrypoint-finney.opentensor.ai:443
const client = createClient(getWsProvider("wss://entrypoint-finney.opentensor.ai:443"));
const api = client.getTypedApi(sub);
// Query TxRateLimit storage (no keys - plain value)
const result = await api.query.SubtensorModule.TxRateLimit.getValue();
console.log("TxRateLimit:", result);Version History
