Storage Map v233 → current

Block of last emission received by a hotkey on a subnet .

Queried by: validatorsminersanalytics

The Big Picture

Tracks when each hotkey last received emission on each subnet. Useful for monitoring neuron activity and debugging emission distribution.

Use Cases

Monitor emission activity
Debug missing emissions
Build emission tracking tools

From Chain Metadata

DMap ( hot, netuid ) --> emission | last hotkey emission on network.

Purpose & Usage

Purpose

Track emission timing for hotkeys per subnet.

Common Query Patterns

Query by (hotkey, netuid)

Query Keys

#	Name	Type	Description
1	key1	AccountId	key1 (AccountId) (hex -> SS58)
2	key2	u16	key2 (u16)

Stored Value

u64

Value in RAO (÷10⁹ for TAO)

RAO -> TAO (/ 10^9)

Code Examples

import { ApiPromise, WsProvider } from "@polkadot/api";
import { stringCamelCase } from "@polkadot/util";

const provider = new WsProvider("wss://entrypoint-finney.opentensor.ai:443");
const api = await ApiPromise.create({ provider });

// Query LastHotkeyEmissionOnNetuid storage
const key1 = "5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY";
const key2 = 0;

const result = await api.query
  [stringCamelCase("SubtensorModule")]
  [stringCamelCase("LastHotkeyEmissionOnNetuid")](
  key1,
  key2
);

console.log("LastHotkeyEmissionOnNetuid:", result.toHuman());
