Chainlink Feed Pallet
A Substrate pallet for integrating Chainlink price feeds and job-based oracles into Polkadot parachains.
What is Chainlink Feed Pallet?
Chainlink-polkadot is a Substrate pallet that integrates Chainlink's decentralized oracle services into Polkadot parachains and Substrate-based blockchains. It enables smart contracts to securely access external data like price feeds and off-chain computation through Chainlink's oracle network. The project solves the problem of bringing reliable real-world data to Polkadot's ecosystem without building custom oracle infrastructure.
Blockchain developers building Substrate-based parachains or standalone chains that need trusted external data feeds, particularly those in the Polkadot ecosystem requiring Chainlink oracle services.
Developers choose Chainlink-polkadot because it provides a standardized, battle-tested way to integrate Chainlink's industry-leading oracle network into Substrate runtimes, saving development time and ensuring data reliability compared to building custom oracle solutions.
Overview
Chainlink-polkadot provides a Substrate pallet that enables Polkadot parachains and other Substrate-based blockchains to integrate Chainlink's decentralized oracle services. It allows smart contracts to securely access external data feeds and off-chain computation through Chainlink's proven oracle network.
Key Features
- Chainlink Feed Integration — Provides a pallet to fetch price feed data (like latest answer, timestamp) from Chainlink oracles directly on-chain.
- Job-Based Oracle Support — Includes
pallet-chainlinkfor interacting with Chainlink's customizable job-based oracle system for arbitrary external data. - Substrate Compatibility — Designed as a standard Substrate pallet, making it easy to add to any Substrate-based runtime.
- Example Implementation — Comes with a full example node and template pallet demonstrating end-to-end integration and usage.
Philosophy
Chainlink-polkadot follows Substrate's modular design philosophy, providing a reusable, configurable component that brings reliable real-world data to Polkadot's ecosystem without reinventing oracle infrastructure.
