Supply-side users deploy and maintain hotspots which provide wireless coverage. Demand-side users use the wireless network for data transfer. Users pay a fee for data transfer (demand-side user) and a fee for hotspot related transactions (supply-side user). Hotspots receive inflationary rewards (token incentives).

Helium is a protocol for building and using decentralized wireless infrastructure. Helium was founded by Shawn Fanning, Amir Haleem & Sean Carey and launched in 2019.

HNT holders own and govern the protocol. They currently receive all of the total data transfer and transaction fees paid by users (revenue). Helium’s investors include a16z, Multicoin Capital, Alameda Research, etc.

# Helium Maximum token supply Methodology

## 1. Overview

The Helium maximum token supply metric represents the total number of HNT tokens that can ever exist according to the protocol's design. This is a protocol-defined constant that establishes the hard cap on token supply, answering the question "What is the theoretical maximum number of HNT tokens that will ever be in circulation?" The calculation uses a predetermined constant value rather than deriving the metric from blockchain data.

## 2. Data sources

This metric relies on protocol specification data rather than blockchain events:
- **Protocol documentation**: Helium's official tokenomics specification defining the maximum token supply
- **Protocol parameters**: Hardcoded constants established at protocol launch
- **Governance decisions**: Protocol-level decisions that establish fundamental economic parameters

## 3. Step-by-step calculation

### Component A: Maximum supply definition
- **Purpose**: Establishes the hardcoded maximum token supply for the Helium protocol
- **Logic**: The metric uses a predetermined constant value of 223,000,000 tokens as the maximum supply. This value is effective starting from the protocol launch date of July 29, 2019. The calculation assigns this constant value with daily granularity timestamps.
- **Key fields**: `token_supply_maximum` (set to 223,000,000), `timestamp` (starting from July 29, 2019), and `timestamp_grain` (set to daily intervals)

### Final aggregation
- **Combining components**: Since this is a single constant value, no aggregation across multiple components is required
- **Currency conversion**: No currency conversion is needed as this metric represents token quantity, not monetary value
- **Time aggregation**: The metric uses daily time boundaries starting from the protocol launch date, with the same maximum supply value applied to all time periods
- **Final calculation**: The final metric value is simply the constant maximum supply of 223,000,000 HNT tokens, standardized through the finalization macro and extended forward through time using a fill-forward strategy to ensure consistent availability across all date ranges from launch to present
