Chainlink’s data standard is now available on AWS Marketplace, giving developers access to Chainlink Data Feeds, Data Streams, and Proof of Reserve through Amazon’s cloud platform.
The launch is designed to help developers and financial institutions connect traditional cloud infrastructure with blockchain networks while maintaining the security, compliance, and reliability requirements used in digital asset applications.
AWS said the integration allows builders to combine AWS services with Chainlink’s oracle infrastructure for tokenization, DeFi, reserve monitoring, and real time trading systems.
Blockchain networks do not natively connect to external data sources, APIs, identity systems, or other chains, a limitation often described as the oracle problem. For tokenized assets, that creates a core challenge because the offchain data that gives those assets value, including prices, ownership records, compliance status, and reserve verification, does not exist directly onchain.
Chainlink addresses that gap by connecting smart contracts to offchain systems, including AWS services, traditional APIs, enterprise infrastructure, and other blockchains.
The network can also support financial institutions and DeFi protocols by bringing market data onchain, moving tokens and messages across blockchains, automating compliance policies, and enabling workflows across onchain and offchain systems.
The AWS Marketplace launch includes three Chainlink services. Data Feeds provide decentralized price and market data for asset valuation, settlement, and risk management. Data Streams deliver faster market data for applications such as perpetual futures, options, and other high performance onchain markets.
Proof of Reserve provides verifiable reserve attestations for stablecoins and other tokenized assets, allowing protocols and issuers to improve transparency and reduce undercollateralization risks.
AWS also outlined reference architectures showing how Chainlink can be used with Amazon API Gateway, AWS Lambda, DynamoDB, Fargate, Secrets Manager, and AWS Key Management Service.
One example uses Chainlink Proof of Reserve to verify backing for a digital asset such as a stablecoin, while another uses Chainlink Data Streams to support automated trading systems for prediction markets.
