Nexus is an oracle infrastructure system delivering real-world data to blockchain networks through validated data feeds. The protocol integrates offchain information including interest rates, asset reserve attestations, and compliance lists onchain using data-priority transaction sequencing and multi-oracle verification mechanisms to support RWA valuation, prediction markets, and automated vault management for tokenized assets.

Gateway Oracle provides custom data sources and price feeds for blockchain applications, supporting DeFi price feeds, custom gas token pricing, and real-world asset pricing with 100,000 requests per second capacity.

DIA Nexus provides customizable oracle infrastructure through traditional data aggregation, enabling transparent price feeds and market data delivery across blockchain networks with configurable methodologies and update frequencies.

Band Price Feed provides decentralized price feeds and real-world data to smart contracts across multiple blockchains. The system aggregates data from sources including Binance, CoinGecko, and CoinMarketCap through BandChain validators, delivers verified price feeds via IBC and bridge contracts, and supports custom oracle scripts for flexible data requests. The Band Standard Dataset offers standardized price feeds for crypto assets, commodities, and fiat currencies with sub-second latency.

Pyth Price Feeds are a core oracle infrastructure providing real-time price data feeds across multiple blockchain networks. Implements a pull-based oracle model with verifiable price attestations and Oracle Integrity Staking for data quality assurance. Publishers stake tokens to back their price feeds, while token holders can delegate stakes to reliable publishers. Delivers sub-second updates for cryptocurrency, equities, forex, and commodities markets through a decentralized publisher network with cryptographic verification.

Supra Oracles delivers decentralized price feeds and data services across multiple blockchains using the DORA protocol with Byzantine Fault Tolerant aggregation from multiple data sources.

Flare Time Series Oracle (FTSO) is an enshrined oracle that provides decentralized data feeds for crypto, equities, and commodities with block-latency updates every 1.8 seconds. Built directly into Flare's core protocol, it leverages the network's full economic security to deliver fast, cost-effective, and manipulation-resistant price data to smart contracts.

Umbrella Network provides decentralized and scalable oracles for blockchain datapoints.

Switchboard was architected to be permissionless and allow users to create and manage their own Switchboard network. Each chain can support many oracle queues, which can have varrying levels of security and trust assumptions.

Scribe implements oracle consensus through Optimistic Schnorr cryptography, enabling gas-efficient data transmission and cryptographic verification. The system aggregates multiple validator signatures while maintaining decentralization and security, with claims of reducing oracle gas costs by over 60%.

Pragma Oracle implements decentralized data aggregation through on-chain computation using STARK proofs, enabling verifiable price feeds and market data. The system processes raw data from whitelisted providers while maintaining transparency and 200ms latency for real-time applications. The platform includes verifiable random function capabilities using Curve25519 cryptography for on-chain randomness generation, optimistic oracle functionality for binary outcome validation through dispute mechanisms, computational feeds for volatility and yield curves, merkle-based data verification, and API services for off-chain data access.

QUEX Oracle is a TEE-based data oracle for smart contracts on EVM chains. It lets contracts fetch, compute, and verify Web2 data using Intel TDX attestation, producing hardware-signed results that are verified on-chain. It supports custom data feeds and pooled executors for request handling.

OmegaX Protocol operates as a health oracle that verifies real-world health outcomes and produces on-chain attestations. The system processes health data from wearables, medical records, and behavioral signals through AI verification to generate cryptographic proofs. These attestations enable smart contracts to execute programmable payouts based on verified health improvements while keeping sensitive medical data off-chain.

Silent Data Oracle connects smart contracts to authenticated Web2 APIs while protecting API keys and sensitive data through Intel SGX attestations. The system enables confidential data integration from external sources without exposing credentials to oracle operators.

DeFi Sentinel is a compliance oracle that provides real-time KYC, AML, wallet screening, and transaction monitoring for DeFi protocols. The system combines on-chain and off-chain data to ensure regulatory compliance at the transaction level.

Infernet implements decentralized oracle network architecture for AI model integration, enabling smart contracts to access off-chain AI computation through distributed nodes. The system routes AI inference requests while maintaining cryptographic verification and cross-chain compatibility.

Molpha Oracle Protocol implements decentralized oracle infrastructure through bonded verifier nodes coordinated via a leader-coordinator model. The system utilizes Schnorr signature aggregation for efficient signature verification and sparse Merkle tree commitments for data integrity proofs. Feed creators define API endpoints and update frequencies while independent verifier nodes fetch data, validate through job-based verification protecting against lazy-signing attacks, and publish aggregated results on-chain with USDC-denominated subscriptions enabling predictable pricing.

A multinode verifiable random function oracle that provides unbiased, verifiable randomness on Solana through a byzantine quorum of fulfillment nodes.
