Provider Details​

Blocksense​

Blocksense's programmable oracles let you access high performance price feeds plus any custom internet data, using familiar DeFi-compatible interfaces, all while enjoying super low costs powered by ZK technology.

To get started, check out the documentation or reach out to the team on Discord.

Supported Networks:

  • Monad Testnet

Chainlink Data Streams deliver low-latency market data offchain, which can be verified onchain. This approach provides decentralized applications (dApps) with on-demand access to high-frequency market data backed by decentralized, fault-tolerant, and transparent infrastructure.

Traditional push-based oracles update onchain data at set intervals or when certain price thresholds are met. In contrast, Chainlink Data Streams uses a pull-based design that preserves trust-minimization with onchain verification.

To get started, check out the documentation.

Supported Networks:

  • Monad Testnet

Chainlink Price Feeds are the quickest way to connect your smart contracts to real-world data such as asset prices.

Data Feeds aggregate many data sources and publish them onchain using a combination of the Decentralized Data Model and Offchain Reporting.

To get started, check out the documentation.

Supported Networks:

  • Monad Testnet

ChainSight​

Chainsight redefines oracles with no-code tools, lowering costs, reducing single-operator risks, and driving scalable, open innovation.

To get started, check out the documentation.

Supported Networks:

  • Monad Testnet

Chronicle​

Chronicle's decentralized oracle network was originally built within MakerDAO for the development of DAI and is now available to builders on Monad.

  • Data Feeds: Builders can choose from 90+ data feeds, including crypto assets, yield rates, and RWAs. Chronicle's data is sourced via custom-built data models, only utilizing Tier 1 sources.
  • Transparency & Integrity: Chronicle's oracle network is fully transparent and verifiable via the Chronicle dashboard. Users can cryptographically challenge the integrity of every oracle update using the 'verify' feature. Data is independently sourced by a community of Validators including Gitcoin, Etherscan, Infura, DeFi Saver, and MakerDAO.
  • Gas Efficiency: Pioneering the Schnorr-based oracle architecture, Chronicle's oracles use 60-80% less gas per update than other oracle providers. This lowest cost per update allows Push oracle updates to be made more frequently, enabling granular data reporting.
  • Every oracle implementation is customized to fit your needs. Implement one of our existing data models or contact Chronicle to develop custom oracle data feeds via Discord.

Developers can dive deeper into Chronicle Protocol's architecture and unique design choices via the docs.

Supported Networks:

  • Monad Testnet

eOracle​

eOracle is an open infrastructure platform that empowers developers to build secure blockchain oracles backed by Ethereum's battle-tested security model. eOracle creates a foundation for specialized data services that combine deep domain expertise with unmatched cryptoeconomic security.

To get started, visit the eOracle documentation.

Supported Networks:

  • Monad Testnet

Gelato VRF​

Gelato VRF (Verifiable Random Function) provides a unique system offering trustable randomness on Monad Testnet.

See this guide to learn how to get started with Gelato VRF.

Supported Networks:

  • Monad Testnet

Orochi​

Orochi Network is the world’s first Verifiable Data Infrastructure, addressing scalability, privacy, and data integrity challenges.

To get started, visit the Orochi documentation.

Supported Networks:

  • Monad Testnet

Pyth​

The Pyth Network is one of the largest first-party oracle networks, delivering real-time data across a number of chains. Pyth introduces a low-latency pull oracle design. Data providers push price updates to Pythnet every 400 ms. Users pull aggregated prices from Pythnet onto Monad when needed, enabling everyone in the onchain environment to access that data point most efficiently.

Pyth Price Feeds features:

  • 400ms latency
  • First-party data sourced directly from financial institutions
  • Price feeds ranging from crypto, stocks, FX, and metals
  • Available on many major chains

Contract Addresses for Monad Testnet:

Supported Networks:

  • Monad Testnet
note

The testnet MON/USD price feed is currently a beta feed on Pyth Network. To use the MON/USD feed, integrate the beta price feed contract instead of the primary price feed contract.

To get the MON/USD price feed offchain, use the beta hermes endpoint: https://hermes-beta.pyth.network

Redstone​

RedStone is the fastest-growing modular oracle, specializing in yield-bearing collateral for lending markets, such as LSTs, LRTs and BTCFi.

To get started, visit the Redstone documentation.

Supported Networks:

  • Monad Testnet

Stork​

Stork is an oracle protocol that enables ultra low latency connections between data providers and both on and off-chain applications. The most common use-case for Stork is pulling and consuming market data in the form of real time price feeds for DeFi.

Stork is implemented as a pull oracle. Stork continuously aggregates, verifies, and audits data from trusted publishers, and makes that aggregated data available at sub-second latency and frequency. This data can then be pulled into any on or off-chain application as often as needed.

To learn more about how Stork works, visit Core Concepts and How It Works.

Supported Networks:

  • Monad Testnet

Supra​

Supra provides VRF and decentralized oracle price feeds (push and pull based) that can be used for onchain and offchain use-cases such as spot and perpetual DEXes, lending protocols, and payments protocols.

To get started, visit the Supra documentation

Supported Networks:

  • Monad Testnet

Switchboard​

Switchboard is a customizable oracle network and oracle aggregator.

To get started, visit the Switchboard documentation.
