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

OP Mainnet is an L2 smart contract platform for decentralized applications on Ethereum. OP Mainnet was founded by Jinglan Wang, Karl Floersch & Kevin Ho and launched in 2021.

Optimism team & investors own and govern the protocol. Optimism’s investors include Paradigm, a16z, IDEO CoLab Ventures, etc.

# OP Mainnet Maximum token supply Methodology

## 1. Overview

The Optimism maximum token supply metric represents the theoretical maximum number of OP tokens that can ever exist according to the protocol's tokenomics design. This metric answers the question "What is the upper limit of OP token supply?" and uses a fixed value established by Optimism's protocol specifications. The calculation involves setting a predetermined maximum supply value that remains constant over time, providing a reference point for understanding token inflation and supply dynamics.

## 2. Data sources

This metric relies on protocol-level specifications rather than blockchain event data:
- **Protocol documentation**: Optimism's official tokenomics specifications and governance decisions
- **Token launch parameters**: Protocol-defined maximum supply limits and launch timeline
- **Governance decisions**: Any protocol upgrades or changes to maximum supply parameters

No blockchain events, transaction data, or external price feeds are required since the maximum supply is a fixed protocol parameter.

## 3. Step-by-step calculation

### Component A: Maximum supply definition
- **Purpose**: Establishes the fixed maximum token supply for the OP token
- **Logic**: Sets the maximum token supply to 4,294,967,296 OP tokens (approximately 4.3 billion tokens) based on Optimism's tokenomics specification. This represents the theoretical upper limit of tokens that can ever be created according to the protocol design
- **Key fields**: `token_supply_maximum` field contains the fixed value of 4,294,967,296 tokens

### Component B: Launch date specification
- **Purpose**: Defines when the OP token became active and maximum supply tracking should begin
- **Logic**: Sets a fixed launch timestamp of May 31, 2022 at 00:00:00 UTC, representing when the OP token was officially launched and when maximum supply tracking becomes relevant
- **Key fields**: `timestamp` field contains the launch date, `timestamp_grain` field specifies daily granularity

### Final aggregation
- **Combining components**: The maximum supply value and launch timestamp are combined into a single record representing the protocol's maximum token supply specification
- **Currency conversion**: No currency conversion is required as this metric represents token quantity, not value
- **Time aggregation**: Uses daily granularity with a fill-forward strategy to maintain the same maximum supply value across all dates from the launch date forward
- **Final calculation**: The final metric value is the fixed maximum supply of 4,294,967,296 OP tokens, which remains constant over time and is reported for each day from the launch date onward using the fill-forward approach to ensure data consistency
