The Big Picture

This is the reverse index for auto-stake - given a subnet, who has auto-stake enabled? Useful for analytics and understanding how many users are using automatic compounding. Higher adoption suggests sophisticated, long-term oriented stakers.

Why This Matters

Want to know how many people use auto-stake on a subnet? This storage lets you enumerate them. Useful for measuring feature adoption and understanding staking behavior.

Example Scenario

Query AutoStakeDestinationColdkeys(netuid=1) returns [coldkey_A, coldkey_B, ...]. These coldkeys have auto-stake configured on subnet 1. Iterate to count or analyze auto-stake users.

Common Questions

Does this include all auto-stake users?: Yes, any coldkey with an auto-stake destination set for this subnet appears in this list.
Can I see where each one stakes?: This gives you the list. Query AutoStakeDestination(coldkey, netuid) for each to see their destination hotkey.

Use Cases

Measure auto-stake adoption rates
Build analytics on compound staking behavior
Index all auto-stake configurations for a subnet
Research staker behavior patterns
Understand validator flows from auto-stake

From Chain Metadata

DMAP ( hot, netuid )--> Vec<cold> | Returns a list of coldkeys that are autostaking to a hotkey

Purpose & Usage

Purpose

Track which coldkeys have auto-stake enabled - useful for analytics and indexing.

Common Query Patterns

Iterate auto-stake users by netuid
Count auto-stake adoption on a subnet
Build auto-stake analytics

Migration Notes

v424 v432 Breaking

key type changed from (AccountId, u16) to (AccountId, NetUid)

Update decoders: SCALE encoding is positional, so any signature change (added, removed, or type-changed fields, or storage shape changes) shifts byte offsets and existing decoders will misparse this item. Re-derive types from the new metadata.

Query Keys

#	Name	Type	Description
1	hot	AccountId	hot (AccountId, hashed key component) (hex -> SS58)
2	netuid	NetUid	netuid (NetUid, hashed key component)

Stored Value

Vec<AccountId> Vec

Vec<cold> (Vec<AccountId>)

Default Value

0x00 (raw SCALE bytes)

Absent keys read as this value — querying a key that has never been written returns this default, not an error or empty result.

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 AutoStakeDestinationColdkeys storage
const hot = "5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY";
const netuid = 1;

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