AWS Lists Chainlink Oracles on Marketplace for Tokenized Finance

Amazon Web Services added three Chainlink oracle services to the AWS Marketplace on April 24, 2026. The listing gives developers a direct path to connect Ethereum smart contracts with Amazon cloud infrastructure for tokenized financial products.

The three services are Chainlink Data Feeds, Chainlink Data Streams and Chainlink Proof of Reserve. Chainlink Data Feeds provide decentralized price and market data aggregated from multiple independent node operators for use in asset valuation, settlement and risk management. Chainlink Data Streams supply high-frequency market data for on-chain systems that must react in real time, such as perpetual futures and options markets. Chainlink Proof of Reserve creates verifiable on-chain attestations that assets backing tokens and stablecoins are fully collateralized, letting protocols automate minting without exposing sensitive internal records.

The announcement was posted on the AWS blog by AWS blockchain specialist Simon Goldberg, who described two reference architectures that place Amazon services between institutional systems and smart contracts. One architecture routes reserve data through Amazon API Gateway and AWS Lambda. A Chainlink Runtime Environment workflow generates a signed report and submits an attested reserve value to an Ethereum smart contract. Amazon DynamoDB retains the raw source data for audit purposes.

The second architecture runs a Data Streams consumer on AWS Fargate. That setup maintains a persistent connection to Chainlink price feeds, verifies cryptographic signatures, evaluates trading rules, and submits signed transactions to a Central Limit Order Book when predefined conditions are met. AWS Secrets Manager and AWS Key Management Service store the private keys used for transaction signing.

Listing the services on the AWS Marketplace lets institutions procure oracle services inside existing cloud accounts and link them to organizational procurement, security and compliance controls. A reference implementation for the Proof of Reserve architecture is available in the AWS samples repository on GitHub. Chainlink Labs is offering consultations to help teams assess use cases.

Beyond price delivery, Chainlink’s Decentralized Oracle Network supports cross-chain token transfers, automation of compliance policies and orchestration of workflows that span on-chain and off-chain systems. Developers and institutions can provision the three Chainlink services directly from the AWS Marketplace and integrate them with Ethereum smart contracts and Amazon cloud services using the provided reference architectures and sample code.
