is a next-generation, high-performance oracle network delivering hyper-fast, cost-efficient, reliable, and highly secure data feeds across multiple blockchains. UDF is the gateway to a new era of decentralized data, enabling real-time, high-frequency data delivery for DeFi, AI-driven applications, and Real-World Assets (RWAs). Supporting both push and pull models through dedicated marketplace contracts deployed on target chains, UDF ensures trust-minimized, low-latency updates while optimizing costs for decentralized applications.

UDF is a decentralized platform that connects on-chain and off-chain data to smart contracts, facilitating real-time data delivery from a variety of sources. UDF supports both EVM and non-EVM networks with a standardized delivery format that's designed to offer developers the flexibility to work across blockchains — providing a flexible, secure, and scalable infrastructure for creating data-driven solutions across diverse platforms.
By offering both Push and Pull Oracle delivery models, UDF allows developers to choose the most suitable method for their use cases. The Push model continuously updates data at predetermined intervals, while the Pull model gives applications the ability to retrieve data only when needed, optimizing efficiency and cost. UDF empowers decentralized applications to interact with real-time data, whether it’s for trading, cross-chain communication, or any other data-dependent function.
Additionally, UDF offers an intuitive and easy to use marketplace hub, a fully integrated ecosystem, acting as the entry point for users to access feeds. It provides users an all in one page to search for assets and manage their data feed subscriptions.
High-Frequency Updates
Ultra-low-latency data updates by leveraging the Entangle Interoperable Blockchain and parallelized Layer 2 rollups. This means 200ms frequency for updates, short block times and reduced data latency. Ideal for high-speed trading, gaming, and AI-driven dApps.
Flexible Data Delivery Models
Choose exactly how your dApp receives oracle data. Select Pull for on-demand data access within transactions (PAYG or subscription), or Push for continuous updates using subscriptions with a fair cost-sharing model. Efficiently and precisely manage your data consumption needs.
Monetization Options
Control your oracle costs with flexible monetization options: Pay-As-You-Go for occasional data requests, Pull Subscriptions for predictable monthly access, and Push Subscriptions with deposits and cost-sharing. UDF provides affordability whatever your scale.
Intuitive Marketplace UI
Find, manage, and buy oracle feeds easily via the intuitive Marketplace UI. Quickly discover available feeds, customize subscription settings, and track your usage seamlessly from a single convenient dashboard. Accessing decentralized data has never been easier.
Customizable Update Parameters
Customize Push updates precisely with selectable price deviation thresholds (0.25%, 0.5%, 1%, 2.5%, 5%) and a default 24-hour heartbeat. Optimize data freshness and costs according to your app’s sensitivity, ensuring timely updates that are aligned with market movements and your specific needs.
Robust Security
Trusted data delivery using Byzantine Fault Tolerance (BFT). Decentralized transmitter nodes securely aggregate and cryptographically verify data, instantly detecting and penalizing malicious activity. UDF guarantees that your application always receives tamper-proof, validated data, even under adverse network conditions.
