The Big Picture

V3 of subnet identity storage. Contains human-readable metadata about subnets including name, description, and contact information.

Use Cases

Display subnet info
Build subnet directories
Research subnet purposes

From Chain Metadata

MAP ( netuid ) --> SubnetIdentityOfV3

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 SubnetIdentitiesV3 storage
const netuid = 1;

const result = await api.query.SubtensorModule.SubnetIdentitiesV3.getValue(netuid);
console.log("SubnetIdentitiesV3:", result);
