The Big Picture

Hotkey swaps on subnets are rate-limited. This tracks when the last swap occurred, enabling cooldown calculations and preventing spam swaps.

Use Cases

Check swap cooldowns
Plan hotkey operations
Debug rate limit errors

From Chain Metadata

DMap ( netuid, coldkey ) --> blocknumber | last hotkey swap on network.

Purpose & Usage

Purpose

Track hotkey swap timing for rate limiting.

Common Query Patterns

Query by (hotkey, netuid)

Query Keys

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

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 LastHotkeySwapOnNetuid storage
const key1 = 0;
const key2 = "5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY";

const result = await api.query
  [stringCamelCase("SubtensorModule")]
