Arbitrum One batches users' transactions and submits them to Ethereum, paying a share of the transaction fees to Ethereum validators (expense).

Arbitrum One is an L2 smart contract platform for decentralized applications on Ethereum. Arbitrum was founded by Offchain Labs and launched in 2021.

ARB tokenholders own and govern the protocol. They currently run the only sequencer and take a cut of the total transaction fees paid by users (revenue). Arbitrum’s investors include Polychain, Alameda Research, Coinbase Ventures, etc.

# Arbitrum One Maximum token supply Methodology

## 1. Overview

The Arbitrum maximum token supply metric represents the theoretical maximum number of ARB tokens that can ever exist according to the protocol's tokenomics design. This is a fixed value defined by Arbitrum's governance and token economics specifications, set at 10 billion ARB tokens. The metric provides a constant reference point for calculating supply utilization ratios and understanding the token's scarcity characteristics.

## 2. Data sources

- **Protocol documentation**: Official Arbitrum governance and tokenomics specifications that define the maximum token supply
- **Token economics parameters**: Formally documented token supply limits established during protocol design
- **Governance records**: Official protocol parameters and constraints set by Arbitrum governance

## 3. Step-by-step calculation

### Component A: Maximum supply definition
- **Purpose**: Establishes the fixed maximum token supply value for ARB tokens
- **Logic**: The maximum supply is set as a constant value of exactly 10,000,000,000 ARB tokens based on the protocol's official tokenomics design. This represents the theoretical ceiling for total token supply that can never be exceeded under the current protocol rules.
- **Key fields**: `token_supply_maximum` field contains the fixed value of 10 billion tokens

### Component B: Reference timestamp
- **Purpose**: Establishes when this maximum supply parameter became effective or publicly known
- **Logic**: The timestamp is set to March 23, 2023, likely corresponding to when the ARB token was launched or when the tokenomics were officially announced. The time granularity is set to daily to enable consistent reporting across time periods.
- **Key fields**: `timestamp` field marks the reference date, `timestamp_grain` specifies daily aggregation

### Final aggregation
- **Combining components**: The maximum supply value and timestamp are combined into a single record representing the protocol's token supply ceiling
- **Currency conversion**: Not applicable as this measures token units, not USD value
- **Time aggregation**: The metric uses a fill-forward strategy to propagate the constant maximum supply value across all time periods, ensuring consistent historical reporting
- **Final calculation**: The final metric value is exactly 10,000,000,000 ARB tokens, representing the immutable maximum supply defined by the protocol's design
