The Big Picture

Global fee tracking using FixedU128 for precise fee-per-liquidity calculations.

Use Cases

Calculate pending fees
Monitor fee accumulation

Purpose & Usage

Purpose

Tracks global fee accumulation for LP fee distribution.

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 FeeGlobalTao storage
const key1 = 0;

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