StakeDeltaSinceLastEmissionDrain

Storage Removed Map v202 → v411

Map ( hot, cold ) --> stake : i128 | Stake added/removed since last emission drain.

From Chain Metadata

Map ( hot, cold ) --> stake: i128 | Stake added/removed since last emission drain.

Purpose & Usage

Purpose

Stores chain state data.

Common Query Patterns

  • Query by key
  • Iterate all entries

Query Keys

#NameTypeDescription
1
key1
AccountId key1 (AccountId) (hex -> SS58)
2
key2
AccountId key2 (AccountId) (hex -> SS58)

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 StakeDeltaSinceLastEmissionDrain storage
const key1 = "5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY";
const key2 = "5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY";

const result = await api.query.SubtensorModule.StakeDeltaSinceLastEmissionDrain.getValue(key1, key2);
console.log("StakeDeltaSinceLastEmissionDrain:", result);
