CREATE WEB3 VALUE WITH CHAINLINK SOLUTIONS


RELIABLE, TAMPER-PROOF NETWORK

Use decentralization, trusted nodes, premium data, and cryptographic proofs to
connect highly accurate and available data/APIs to any smart contract.


SEAMLESS CONNECTION TO ANY API

Build on a flexible framework that can retrieve data from any API, connect with
existing systems, and integrate with any current or future blockchain.


PROVEN, READY-MADE SOLUTIONS

Integrate pre-built, time-tested oracle solutions that already secure tens of
billions in smart contract value for market-leading decentralized applications.



HIGHLY RELIABLE AUTOMATION

Use a decentralized network of Chainlink Automation nodes to automate contracts,
mitigating risk of manual interventions and centralized servers. 

Deploy your Chainlink smart contract

POWERING THE FUTURE OF SMART CONTRACTS

“Part of composability is that you don’t have to build everything by yourself.
Chainlink’s oracle is very good, and it’s part of this whole composability idea,
it’s vital.”


Stani Kulechov

CEO



“We really did our due diligence and looked around... Chainlink is definitely
the most established, and every time we dealt with them the level of expertise
was incredible so I feel like we are in good hands.”

Justin Moses

CTO



“This product is built on the foundation of blockchain technology and utilizes
Arbol’s smart contracts along with decentralized weather data provided by
Chainlink to offer users a product unlike any other on the market.”

Siddhartha Jha

CEO and Founder



"Public network infrastructure provisioning has been a core business model of
telco companies for decades. Providing critical Web3 infrastructure by running
Chainlink oracle nodes has enabled new revenue streams and opened the door to
Web3 opportunities."

Dr. Andreas Dittrich

Head of Blockchain Solutions Center
