UMA Protocol Implements Two Major Upgrades: UMIP-185 and UMIP-186
UMA Protocol Implements Two Major Upgrades: UMIP-185 and UMIP-186
🔐 Oracle Gets Pickier
Two significant upgrades have been implemented in the UMA Protocol:
UMIP-185: Optimistic oracle now uses hash and pointers instead of full ancillary data, reducing onchain data and gas costs
UMIP-186: Settlement Price Approval Threshold (SPAT) increased from 50% to 65%, requiring stronger consensus for dispute votes
The SPAT change affects only contentious cases (2% of total votes). In 2025, only 6 out of 291 votes would have been impacted. This upgrade strengthens security for high-stakes decisions while maintaining efficiency.

The Orb has spoken… A new upgrade has been cast: UMIP-185 is now live. UMIP-185 lets the optimistic oracle use a hash and pointers instead of full ancillary data. This reduces onchain data, cuts gas costs, and boosts efficiency.
There is a new proposal up for discussion on the UMA discourse. This proposal modifies the Settlement Price Approval Threshold (SPAT) parameter within UMA’s VotingV2 contract from 50% to 65%. Leave us your thoughts, link below.
UMA Secures Super Bowl LX Predictions on Polymarket
**UMA is providing oracle infrastructure for Super Bowl LX prediction markets on Polymarket.** The protocol will secure onchain outcomes for the full weekend of Super Bowl betting activity. UMA's optimistic oracle technology enables decentralized verification of real-world events for prediction markets. - UMA serves as the oracle layer verifying Super Bowl outcomes - Polymarket has seen over $67M in Super Bowl betting volume - The integration demonstrates growing adoption of decentralized prediction markets This continues UMA's role in powering the prediction market infrastructure stack.
MetaMask Integrates UMA-Secured Bridging and Predictions
MetaMask has integrated two major UMA-secured protocols directly into its wallet interface: - **Across Protocol** for cross-chain bridging - **Polymarket** for prediction markets Both services leverage UMA's optimistic oracle technology for security. This integration brings decentralized bridging and prediction market functionality directly to MetaMask users without leaving the wallet interface. The move represents a significant step in making DeFi infrastructure more accessible to mainstream users through familiar interfaces.
Delphi Digital Launches Research Markets on Polymarket
**Delphi Digital** has launched prediction markets on **Polymarket**, secured by UMA's optimistic oracle technology. - The markets focus on industry research outcomes - UMA provides the oracle infrastructure ensuring market security - This represents a new approach to research validation through prediction markets The integration combines Delphi Digital's research expertise with Polymarket's prediction market platform and UMA's decentralized oracle system.
UMA Doubles Minimum Stake Requirement for Voting Gas Rebates to 1000 Tokens
**UMA increases voting participation barrier** Starting November 1st, UMA voters need to stake **1000 $UMA tokens** (up from 500) to qualify for gas rebates. This follows the initial introduction of minimum staking requirements in February 2025, when rebates shifted from universal coverage to requiring 500+ tokens. **Key changes:** - Minimum stake doubles from 500 to 1000 $UMA - Gas rebate eligibility becomes more restrictive - Change reflects ongoing cost management efforts The adjustment continues UMA's strategy to control rebate expenses, which previously surged 5x since July 2024.

UMA's Optimistic Oracle Secures Polymarket with Real-World Data
**UMA's Optimistic Oracle** brings real-world data onchain to secure prediction markets like Polymarket. The system works through **three key steps**: - **Proposal**: Event outcomes are submitted to the oracle - **Challenge Period**: Proposed outcomes can be disputed within a set timeframe - **Resolution**: Challenged outcomes trigger decentralized dispute resolution This **decentralized approach** eliminates single points of failure, ensuring fair and trustworthy market outcomes through consensus rather than centralized control. **Key achievements**: - Resolved over **10,000 markets** for Polymarket - Secures multiple prediction platforms including poly_bet, ForeProtocol, and predictdotfun The Optimistic Oracle addresses prediction markets' core challenge: **accurately determining real-world event outcomes onchain** while maintaining decentralized integrity.
