On April 24, 2026, Chainlink Labs unveiled three oracle services on the AWS Marketplace, a move aimed at enhancing blockchain tokenization efforts. AWS architect Simon Goldberg highlighted this development in a blog post, addressing the so-called “oracle problem” that restricts blockchain networks from seamlessly accessing external data sources or APIs.
The new offerings—Chainlink Data Feeds, Chainlink Data Streams, and Chainlink Proof of Reserve—each serve a unique purpose within the tokenization framework actively pursued by financial institutions leveraging cloud infrastructure.
Chainlink Data Feeds provide decentralized price and market data, aggregated from multiple independent node operators. Financial institutions can utilize these feeds for various functions, including asset valuation, settlement processing, and risk management. The architecture ensures that data remains reliable and robust.
Chainlink Data Streams are designed for high-frequency data delivery, catering to on-chain systems that need to respond immediately to market fluctuations. This service is particularly beneficial for perpetual futures and options markets, where rapid and precise data is crucial for settling positions and executing risk controls.
The Chainlink Proof of Reserve service focuses on providing verifiable on-chain attestations for decentralized finance (DeFi) protocols and stablecoin issuers. This functionality enables institutions to demonstrate reserve transparency and automate token minting processes, all while safeguarding sensitive internal data from public exposure.
In his announcement, Goldberg detailed two reference architectures that illustrate how these services operate in tandem with Amazon cloud offerings and Ethereum smart contracts. The first architecture directs reserve data through Amazon API Gateway and AWS Lambda. It involves a Chainlink Runtime Environment workflow that generates a signed report, submitting an attested reserve value to an Ethereum smart contract, while Amazon DynamoDB archives the raw source data for auditing.
The second architecture utilizes a Data Streams consumer running on AWS Fargate, which maintains a constant connection to Chainlink price feeds. It verifies cryptographic signatures, applies trading rules, and sends signed transactions to a Central Limit Order Book, activating these processes when predetermined conditions are satisfied. AWS Secrets Manager and AWS Key Management Service play vital roles in storing private keys necessary for transaction signing.
Goldberg emphasized that the drive toward tokenization is fueled by the desire to unlock liquidity, minimize settlement times, and introduce new asset classes. Chainlink’s listing on AWS Marketplace offers financial institutions a seamless procurement path that integrates with their existing cloud workflows.
Beyond merely providing price data, Chainlink’s Decentralized Oracle Network also facilitates cross-chain token transfers, compliance policy automation, and workflow orchestration that spans both on-chain and off-chain systems. Developers interested in these tools can access them directly via the AWS Marketplace. Additionally, the Chainlink Labs team stands ready to provide consultations tailored to specific use cases, with a reference implementation for Proof of Reserve also available in the AWS samples repository on GitHub.
