Stake

Storage Removed Map v101 → v411

REMOVED. Amount of TAO staked from a coldkey to a hotkey on a subnet .

Queried by: stakersvalidatorsdelegatorsanalyticswallets

The Big Picture

Stake is the core data structure for Bittensor economics. Every staking relationship - who staked how much to whom on which subnet - is recorded here. This drives validator power, emission distribution, and the entire incentive mechanism.

Why This Matters

Want to know how much you've staked somewhere? How much stake your validator has? Who's staking to whom? This is the source of truth for all staking data.

Example Scenario

You staked 100 TAO to Validator X on subnet 1. Query Stake(netuid=1, hotkey=X, coldkey=you) returns 100000000000 (in RAO). This is your current stake position.

Common Questions

Why is the value so large?: Stake is stored in RAO (1 TAO = 10^9 RAO). Divide by 1,000,000,000 to get TAO.
Can I iterate all my stakes?: Yes, iterate Stake with your coldkey as prefix to find all hotkeys you're staking to.

Use Cases

Check how much you have staked to a validator
Build staking leaderboards and analytics
Calculate portfolio value across validators
Monitor delegation changes over time

From Chain Metadata

(DEPRECATED) DMAP ( hot, cold ) --> stake | Returns the stake under a coldkey prefixed by hotkey.

Purpose & Usage

Purpose

Tracks delegation relationships and stake amounts for validation.

Common Query Patterns

Query stake for a specific coldkey-hotkey-netuid combination
Iterate all stakes for a coldkey
Check if a hotkey has stake from a coldkey

Query Keys

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

Stored Value

u64

Value in RAO (÷10⁹ for TAO)

RAO -> TAO (/ 10^9)

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

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