UMA’s oracle uses a “true unless disputed” pattern, in which anyone can propose or dispute data. In cases of disputes, UMA’s network of tokenholders vote to verify the data, earning inflationary token rewards for correct votes.

UMA is an optimistic oracle (OO) that can verify any statement proposed on the blockchain. UMA functions as a decentralized truth machine that includes human reasoning backed by economic incentives. UMA was co-founded by Hart Lambur in 2018 and launched in 2020.

UMA tokenholders own and govern the protocol. They do not currently take a cut of the total oracle call & periodic fees paid by users (revenue). UMA's investors include Placeholder and Blockchain Capital.

# UMA Maximum token supply Methodology

## 1. Overview

This metric represents the maximum possible token supply for UMA protocol tokens. Unlike circulating or total supply metrics that are calculated from blockchain data, the maximum token supply is a predetermined protocol parameter that represents the absolute cap on how many UMA tokens can ever exist. This metric answers the question "What is the theoretical maximum number of UMA tokens that can be created?" and is essential for understanding the token's scarcity model and inflation potential.

## 2. Data sources

This metric relies on protocol specification data rather than blockchain transaction data:
- **Protocol documentation**: UMA's official tokenomics specifications that define the maximum supply cap
- **Token contract parameters**: The hardcoded maximum supply value from UMA's token contract design
- **Protocol launch information**: Official launch date when UMA tokens became available

## 3. Step-by-step calculation

### Component A: Static supply definition
- **Purpose**: Establishes the maximum token supply value as defined in UMA's protocol specifications
- **Logic**: Uses the predetermined maximum supply of 115,429,461 tokens as specified in UMA's tokenomics design. This value represents the absolute ceiling for token creation and cannot be exceeded regardless of minting, staking rewards, or other protocol activities
- **Key fields**: `token_supply_maximum` set to 115,429,461, `timestamp` set to UMA's launch date of January 9, 2020, `timestamp_grain` set to daily intervals

### Final aggregation
- **Combining components**: Since this is a single static value, no aggregation across multiple components is needed
- **Currency conversion**: Not applicable as this metric represents token quantity, not monetary value
- **Time aggregation**: The metric uses a daily time grain and applies a fill-forward strategy, meaning the same maximum supply value is reported for every day from the launch date forward
- **Final calculation**: The final metric value is simply the static maximum supply of 115,429,461 UMA tokens, standardized through the finalization macro to ensure consistent formatting with other Token Terminal metrics
