Oracles

Blockchain oracles are third-party services that provide data to smart contracts running on a blockchain network. Oracles act as intermediaries between the blockchain network and the outside world, enabling smart contracts to execute based on real-world events or data.

SupraOracles​

Supra is a novel, high-throughput Oracle & IntraLayer: A vertically integrated toolkit of cross-chain solutions (data oracles, asset bridges, automation network, and more) that interlink all blockchains, public (L1s and L2s) or private (enterprises).

Supra’s distributed Verifiable Random Function (dVRF) solution provides unbiased, unpredictable, and provably fair randomness for blockchain gaming and casinoFi use-cases such as loot boxes, NFT-minting, character upgrades, odds-based games, and on-chain lotteries. Supra’s dVRF design uses a novel non-interactive Distributed Key Generation (NI-DKG), allowing it to be very low-latency and cryptographically secure. Supra’s dVRF paper was accepted into ACM CCS 2023, a top cybersecurity conference.

DIA​

DIA is a cross-chain, trustless oracle network delivering verifiable price feeds for Fuse. DIA sources raw trade data directly from primary markets and computes it onchain, ensuring complete transparency and data integrity.

Key Features:

  • Complete verifiability from source to destination smart contract.
  • Direct data sourcing from 100+ primary markets eliminating intermediary risk.
  • Support for 20,000+ assets across all major asset classes.
  • Custom oracle configuration with tailored sources and methodologies.

Data Products:

  • Token Price Feeds: Real-time market prices for assets across CEXs and DEXs.
  • Fundamental Feeds: Fair value pricing and backing data (NAV, Proof of Reserve, and more).
  • Real-World Asset (RWA) Feeds: Traditional financial data including Equities, FX rates, commodities, and ETFs.
  • Randomness: Verifiable random number generation for gaming, lotteries, and more.

Get Started:

A centralized version on Chainlink data feeds will be launched soon.
