Volume Bubbles Chart (1h)
Each 1-hour candle's volume is signed by its direction (up candles count as net buying, down candles as net selling) and drawn as a bubble at the closing price, green for buying and red for selling. Bubble size and colour intensity show how strong that flow is compared with the last 300 candles: the strongest 30% get full bubbles with their USD value, the rest stay as small dots. Unusually large bubbles flag aggressive buying or selling worth a closer look, often near breakouts, reversals or key levels.Seasonal Chart
Plots one line per calendar year showing the % change since the start of that year, with the current year highlighted against up to four previous years. Lining the years up on the same calendar shows whether the price tends to rise or fall in the same months, helping you spot recurring seasonal patterns. Treat it as context rather than a forecast: past seasonality does not guarantee future moves.UMA Markets
UMA Historical Data
About UMA (UMA)
UMA is an optimistic oracle that brings verifiable information onto blockchains. Its Optimistic Oracle accepts proposed answers and sends disputed requests to the Data Verification Mechanism, where staked UMA holders vote.
Optimistic Oracle requests
UMA's Optimistic Oracle lets a proposer submit an answer to a defined data request. A request can include instructions for how the result should be determined, a proposer reward and a bond. If nobody disputes the proposed answer during the configured challenge period, it can be accepted without a community vote. This design is intended to handle many ordinary requests quickly while reserving arbitration for contested claims.
Disputes and the DVM
When a request is disputed, UMA's Data Verification Mechanism resolves the disagreement through tokenholder voting. The documentation describes a commit-and-reveal process: voters first commit a hidden vote and later reveal it. This reduces the ability to copy votes before the reveal phase. UMA's current overview reports that 99.8% of requests resolve without escalation. This is a project-reported metric, not a guarantee for every integration.
UMA staking and voting
The DVM uses staked UMA to resolve disputes. UMA's documentation says voters who fail to vote or vote against the majority can be slashed, with the slashed amount redistributed to majority voters. The voting walkthrough lists a 24-hour commit period followed by a 24-hour reveal period, and a seven-day unstaking cooldown. These are protocol-specific rules and can be changed through governance, so current parameters should be checked before participating.
Use across applications
UMA's documentation describes oracle use in cross-chain bridges, prediction markets, insurance protocols and custom derivatives. Optimistic Oracle V2 and V3 support different integration patterns. V2 uses data requests answered by proposers, while V3 lets integrations submit assertions with their own parameters. Developers should choose the version that matches their application rather than treating both interfaces as identical. Official documentation also distinguishes Optimistic Oracle V2 data requests from V3 assertions. Integrators need to choose the pattern that matches their request format, evidence requirements and challenge settings.
Governance and risks
UMA holders can participate in governance through UMA Improvement Proposals and votes in the DVM. Oracle security depends on the quality of request wording, incentives, challenge windows and voter participation. A result may be disputed when evidence is ambiguous or a request is poorly specified. UMA provides a dispute process. Applications still need clear data definitions and correct oracle integration. The documentation says an undisputed assertion can resolve after a configurable liveness period, while disputed cases move to the DVM. Each integration sets its own interval. Different applications may therefore use different challenge settings.

UMA (UMA) FAQ
What is the current price of UMA (UMA)?
UMA's live composite quote is $0.3524; the current value is displayed above the chart beside the coin name. UMA's Optimistic Oracle lets proposers submit answers to defined data requests, with a dispute mechanism for contested claims. The quote describes token trading, not whether an oracle request is correct.
What is UMA used for?
UMA is used in an optimistic-oracle system where proposed answers can be disputed. If a request is challenged, the Data Verification Mechanism resolves the dispute through tokenholder voting. The protocol is used by applications such as cross-chain bridges and prediction markets, but each integration defines its own request and challenge settings.
How much UMA is in circulation?
UMA's circulating supply field reads 92,575,367 UMA. The protocol's DVM uses staked UMA for dispute voting, and the documentation describes slashing for voters who miss or oppose the majority result. Those rules explain participation; they are separate from the market-data count of tokens in circulation.
What is UMA's all-time high?
UMA's recorded all-time market peak is $41.56; the date shown for it is Feb 4, 2021. The documentation describes the Data Verification Mechanism as the dispute-resolution system for contested oracle requests. That protocol role is project-specific, while the peak records market history.
How has UMA performed over time?
In FMchart's composite price history (since September 2020), UMA's strongest monthly result came in January 2024 (+100.9%) and its lowest in September 2020 (-47.6%); positive annual closes numbered 3 of 5 full calendar years. UMA's dispute-resolution design does not measure the token's monthly return. Its voting walkthrough lists 24-hour commit and reveal windows.
How does UMA work?
An UMA proposer submits a response to a request with instructions for determining the outcome, a reward and a bond. If nobody challenges it during the liveness period, the proposal can be accepted. The challenge window is configurable, so applications should specify the evidence and timing their request requires.
Does UMA support staking or governance?
UMA's DVM uses a commit-and-reveal process with a 24-hour commit period and a 24-hour reveal period in the documented voting walkthrough. The documentation also lists a seven-day cooldown before staked UMA can be withdrawn. These are specific protocol rules and may change through governance.
What makes UMA different?
UMA combines an optimistic oracle with a separate dispute mechanism, rather than requiring a community vote for every data request. Its documentation says 99.8% of requests are currently resolved without escalation. That is a project-reported rate, not a guarantee that an individual assertion will avoid challenge.
What are the main uses of UMA?
UMA's docs list cross-chain bridges, prediction markets, insurance protocols and custom derivatives among oracle use cases. V2 handles requests answered by proposers, while V3 allows integrations to submit assertions with parameters. Developers need to choose the version that fits their contract rather than treating the interfaces as interchangeable.
What risks should readers understand about UMA?
Oracle security depends on precise request wording, incentives, challenge periods and active voting. UMA's DVM can penalize incorrect or absent votes, but unclear evidence can still make a claim difficult to resolve. Smart-contract errors, governance decisions and poorly configured integrations remain risks even when the oracle protocol has a dispute process.
