Legacy. This page documents third-party oracle integrations from the legacy Gravity Alpha Mainnet (L2). Gravity Mainnet (L1) is integrating a range of oracle services; for now the protocol-level Native Oracle — validator-attested external data with consensus-grade security — is supported by default.

Overview

Blockchain oracles act as bridges between smart contracts and real-world data. They provide essential off-chain information such as price feeds, random numbers, and event outcomes that blockchains cannot access natively. Oracles vary in design, with some using push models (regular on-chain updates) and others using pull models (on-demand data requests). The quality of an oracle is measured by its speed, accuracy, cost-efficiency, and security against manipulation.

Third-Party Oracles

Pyth

The Pyth Network is the largest first-party Oracle network, delivering real-time data across a vast number of chains. Pyth introduces an innovative low-latency pull oracle design, where users can pull price updates on-chain when needed, enabling everyone in the blockchain environment to access that data point most efficiently. Pyth network updates the prices every 400ms, making Pyth the fastest on-chain oracle.

Users can also opt to use push model oracles through Pyth by running a scheduler.

Pyth Oracle Features:

• 400ms latency

• Most efficient and cost-effective Oracle

• First-party data sourced directly from financial institutions

• Price feeds ranging from Crypto, Stock, FX, Metals

• Available on all the largest chains
