The Big Picture

sqrt(price) format enables efficient tick math.

Use Cases

Calculate swap outputs
Display current price

From Chain Metadata

Storage for the square root price of Alpha token for each subnet.

Purpose & Usage

Purpose

Core price state for concentrated liquidity.

Common Query Patterns

Query by netuid

Part of: Concentrated Liquidity

Query Keys

#	Name	Type	Description
1	netuid netuid raw: key1	u16	key1 (u16)

Stored Value

FixedU128

value (FixedU128)

Decoding the value

FixedU128 (Q64.64 fixed-point)

FixedU128 encodes as Q64.64: raw bits divided by 2^64 gives the rational. Magnitude > 0 means non-zero.

const fraction = Number(value as bigint) / 2 ** 64;

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 AlphaSqrtPrice storage
const key1 = 0;

const result = await api.query.Swap.AlphaSqrtPrice.getValue(key1);
console.log("AlphaSqrtPrice:", result);
