Amazon Web Services Adds Three Chainlink Services To Its Marketplace

Amazon Web Services has added three Chainlink oracle services to the AWS Marketplace: Data Feeds, Data Streams, and Proof of Reserve. Enterprise developers can now access these tools directly through existing AWS procurement workflows, removing a significant barrier for financial institutions looking to build blockchain-connected applications.

What Is The Oracle Problem, And Why Does It Matter?

Blockchain networks cannot natively connect to external data sources, APIs, or other chains. This is known as the oracle problem. For institutions exploring tokenization, it creates a practical gap: real-world data such as asset prices, reserve balances, and compliance records simply does not exist onchain by default.

Chainlink's Decentralized Oracle Network (DON) addresses this by creating a secure, bidirectional connection between offchain systems, including AWS services, and onchain smart contracts. The AWS Marketplace listing gives institutions a familiar procurement path to access that infrastructure.

The Three Chainlink Services Now On AWS Marketplace

The integration covers three distinct products, each targeting a specific enterprise use case.

• Chainlink Data Feeds aggregate price and market data from multiple independent node operators. Financial institutions use them for asset valuation, settlement processing, and risk management. The decentralized aggregation model is designed to resist data manipulation from any single source.

• Chainlink Data Streams handle high-frequency data delivery for applications that need to react to market movements in real time. Perpetual futures markets, options platforms, and other high-performance onchain systems fall into this category. These were previously difficult to build onchain due to latency constraints.

• Chainlink Proof of Reserve provides verifiable onchain attestations confirming that stablecoins and other tokenized assets are fully backed by underlying reserves. DeFi protocols and asset issuers can use it to automate token minting and demonstrate reserve transparency without exposing sensitive internal data publicly.

How The Integration Works In Practice

AWS's announcement included two reference architectures that show how these services connect to existing cloud infrastructure.

The first covers proof-of-reserve monitoring. Reserve data flows through Amazon API Gateway and AWS Lambda, gets stored in Amazon DynamoDB, and is then picked up by a Chainlink Runtime Environment workflow running on the DON. That workflow generates a signed report and submits an attested reserve value to an Ethereum smart contract. DynamoDB retains the raw data for audit purposes.

The second covers real-time trading on prediction markets. A Data Streams consumer runs on AWS Fargate, maintaining a live connection to Chainlink price feeds. The system verifies cryptographic signatures, evaluates trading rules, and submits signed transactions to a Central Limit Order Book when preset conditions are met. Private keys are stored using AWS Secrets Manager and AWS Key Management Service.

Chainlink's Compliance Credentials Add Weight To The Launch

The AWS integration follows Chainlink recently completing a SOC 2 Type 2 examination conducted by Deloitte and Touche LLP, a Big Four accounting firm. The audit covered Chainlink's Cross-Chain Interoperability Protocol (CCIP) and Data Feeds products, including Proof of Reserve and Net Asset Value feeds.

SOC 2 Type 2 differs from Type 1 in a critical way. Type 1 checks whether security controls are properly designed at a single point in time. Type 2 tests whether those controls held up consistently over a sustained period. Chainlink is now the only oracle platform in the blockchain industry to hold SOC 2 Type 1, SOC 2 Type 2, and ISO/IEC 27001:2022 certification at the same time. For regulated institutions, that kind of third-party attestation from a firm like Deloitte carries far more weight than self-reported security claims.

Since launching on mainnet in 2019, Chainlink's oracle networks have secured $29 trillion in transaction value across more than 80 public and private blockchains.

Conclusion

AWS Marketplace now gives enterprise developers a direct procurement path to Chainlink's Data Feeds, Data Streams, and Proof of Reserve. Combined with Chainlink's SOC 2 Type 2 certification from Deloitte and $29 trillion in secured transaction value, the integration gives financial institutions a compliance-ready way to connect AWS cloud infrastructure with blockchain networks.
