Chainlink VRF V1
Project Links
Description
Chainlink VRF V1 (Verifiable Random Function) provided provably fair, tamper-proof randomness to smart contracts. Each request generated a random value and cryptographic proof, which was published and verified onchain before use. Chainlink officially deprecated VRF V1 and replaced it with VRF V2.5 on November 29, 2024.Category: Oracle

Chainlink CCIP (Cross-Chain Interoperability Protocol)
Project Links
Description
Chainlink CCIP is a blockchain interoperability protocol facilitating token transfers, arbitrary messaging, and programmable token transfers across chains. The system uses decentralized oracle networks for transaction validation, implements rate limiting for risk management, and features timelocked upgrades through role-based access control. CCIP enables atomic and hybrid settlement workflows across public and private blockchains.Category: Cross-chain Infrastructure

Chainlink VRF (Verifiable Random Function)
Project Links
Description
Chainlink VRF generates verifiable random numbers for smart contracts through cryptographic proof mechanisms published and verified onchain. The system prevents tampering by oracle operators, developers, or miners through cryptographic verification of random value generation. VRF v2.5 supports subscription-based and direct funding payment models with LINK or native tokens.Category: Developer Tooling
Chainlink Automation
Project Links
Description
Chainlink Automation executes smart contract functions through decentralized oracle networks monitoring onchain conditions and time-based triggers. The system automates transaction execution without centralized infrastructure, uses the same node operators securing Chainlink data feeds, and enables developers to offload operational maintenance for protocol automation workflows.Category: Developer Tooling
Chainlink Functions
Project Links
Description
Chainlink Functions provides smart contracts with trust-minimized compute infrastructure for API data retrieval and custom computation execution. The system operates through decentralized oracle networks that execute source code in serverless environments, aggregate independent results through consensus, and support threshold-encrypted secrets for authenticated API access.Category: Developer Tooling
DataLink
Project Links
Description
DataLink is a turnkey Chainlink service for institutional data providers. Providers select data, connect an existing API, and use Chainlink infrastructure for secure onchain delivery and distribution to 40+ blockchains and 2,400+ protocols and financial institutions. Supported datasets include equities, foreign exchange rates, bonds, derivatives, commodities, indices, perpetual funding rates, volatility data, and custom datasets.Category: Data
Chainlink Runtime Environment (CRE)
Project Links
Description
Chainlink Runtime Environment (CRE) is a developer platform that lets builders compose modular oracle capabilities into custom cross-chain workflows using Go, TypeScript, and other languages. It re-architects Chainlink's platform into purpose-built decentralized oracle networks (DONs) per capability, coordinated through DON-to-DON communication. CRE enables institutional-grade smart contracts to operate across public and private blockchains with built-in compliance and privacy support.Category: Developer Tooling
Chainlink Privacy Standard
Project Links
Description
Chainlink Privacy Standard is a developer framework that enables private smart contracts on public and private blockchains by combining trusted execution environments (TEEs), zero-knowledge proofs, and the DECO protocol. It provides confidential computing through Chainlink Confidential Compute, selective disclosure for regulatory compliance, and cross-chain private transaction support via CCIP. Institutions use the standard to protect trade logic, tokenized asset metadata, and KYC credentials while remaining auditable to designated counterparties.Category: Developer Tooling
Chainlink
Project Links
Description
Chainlink is an all-in-one oracle platform for building blockchain applications that interoperate across blockchains and existing systems. Its infrastructure includes cross-chain messaging, market and data feeds, Data Streams, DataLink, Proof of Reserve, SmartData, Functions, Automation, VRF, privacy, compliance, and orchestration capabilities for financial institutions, capital markets organizations, DeFi protocols, developers, and other onchain applications.Category: Oracle
Chainlink Network
Project Links
Description
The Chainlink Network consists of multiple independent decentralized oracle networks operated by node operators and data providers. It provides secure data delivery, offchain computation, automation, verifiable randomness, and cross-chain connectivity for smart contracts across multiple blockchains.Category: Oracle
Data Streams
Project Links
Description
Chainlink Data Streams is a pull-based oracle service that continuously generates high-frequency market data offchain, validates reports onchain, and lets decentralized applications retrieve data on demand. It uses decentralized oracle networks and supports low-latency trading, liquidations, derivatives, tokenized equities, ETFs, and other onchain financial applications with metadata such as market status and data freshness.Category: Oracle
SmartData
Project Links
Description
SmartData is a Chainlink suite of data oracles for tokenized real-world assets. It includes reserve-status feeds, NAVLink feeds for real-time net asset value, and SmartAUM feeds for assets managed on behalf of clients.Category: Oracle
Cross-Chain Interoperability Protocol (CCIP)
Project Links
Description
Cross-Chain Interoperability Protocol (CCIP) is Chainlink’s cross-chain infrastructure product for DeFi and institutional interoperability. It provides cross-chain messaging, programmable token transfers, and Cross-Chain Token support, powered by Chainlink decentralized oracle networks with modular security, compliance, and privacy capabilities.Category: Cross-chain Infrastructure
Chainlink For Agents

Description
Chainlink for Agents provides on-demand access to Chainlink Data Streams, Chainlink Runtime Environment-powered execution with error handling and gas sponsorship, CCIP cross-chain operations, transaction delivery, and x402 pay-per-call payments in USDC on Base.Category: AI Agent Platform
Chainlink Proof Of Reserve
Project Links
Description
A production Chainlink oracle service that brings offchain and cross-chain reserve information onchain. Its feeds verify collateralization and can connect to minting, redemption, trading, or other protocol logic to enforce reserve thresholds and halt actions when backing is insufficient.Category: Oracle
Chainlink Digital Transfer Agent (DTA) Technical Standard
Project Links
Description
The DTA Technical Standard combines DTA Request Management and Request Settlement smart contracts with CCIP, ACE, NAVLink Feeds, and the Chainlink Runtime Environment.
