The Big Picture
TAO flows in (staking) and out (unstaking) of subnets. This signed value tracks the net flow, used in economic calculations for subnet weight.
Use Cases
- Monitor TAO flow dynamics
- Research subnet economics
- Build flow dashboards
From Chain Metadata
MAP ( netuid ) --> subnet_tao_flow | Returns the TAO inflow-outflow balance.
Purpose & Usage
Purpose
Track net TAO movement for subnet economics.
Common Query Patterns
- Query by netuid
Query Keys
| # | Name | Type | Description |
|---|---|---|---|
| 1 | netuid | u16 | netuid (u16, hashed key component) |
Stored Value
subnet_tao_flow (i64)
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 SubnetTaoFlow storage
const netuid = 1;
const result = await api.query.SubtensorModule.SubnetTaoFlow.getValue(netuid);
console.log("SubnetTaoFlow:", result);Version History
