AWS re:Invent 2025 - Web3 + AI: Agents that mean business (DAT318)

Summary of AWS re:Invent 2025 - Web3 + AI: Agents that mean business (DAT318)

Overview of Web3 at AWS

• AWS sees web3 as extending far beyond just cryptocurrency, with many decentralized applications leveraging various web3 technologies
• Key web3 technologies include blockchain networks, decentralized storage, and smart contract execution
• Building web3 products requires making many foundational choices around protocols, custody, smart contracts, and more
• AWS aims to provide managed services, DIY solutions, and a robust partner ecosystem to help customers navigate the complexity of web3

AWS Managed Services for Web3

• AWS offers services like EC2 to run blockchain nodes, with built-in protections like no operator access to customer content
• AWS also provides specialized services like Nitro Enclaves and KMS for secure wallet and custody solutions
• AWS Blockchain Node Runners is an open-source project providing blueprints to spin up nodes for popular protocols
• AWS Public Blockchain Data provides free access to datasets from leading blockchain protocols

The Rise of Digital Assets and Payments

• Stable coins and digital asset payments are emerging as a key trend, driven by institutional and government adoption
• Traditional payment systems have challenges like high fees, long settlement times, currency fluctuations, and multiple intermediaries
• Digital asset payments can address these issues by reducing costs, enabling micro-transactions, and improving cash flow and settlement times

X42: An Open Standard for Internet-Native Payments

• Presented by Coinbase, X42 is an open standard for programmatic, neutral, and internet-native payments without human involvement
• X42 leverages stable coins to enable fast, low-cost transactions between clients and servers
• The X42 protocol defines a standard way for clients to discover payment requirements, construct payments, and have servers verify and settle them
• X42 is designed with principles of safety, nativeness, ease of adoption, and extensibility in mind

Building Agentic AI Payment Systems on AWS

• AWS provides a stack of foundational services like Bedrock, Agent Core, and identity/observability tools to build agentic AI applications
• Agent Core Gateway allows AI agents to discover and use external payment-enabled tools and services via the X42 protocol
• Example use case: A travel agent AI using Agent Core and X42 to programmatically discover, access, and pay for data services like flight schedules, weather, and points of interest
• The architecture leverages AWS services like CloudFront, Lambda@Edge, and secure wallets powered by Coinbase's Nitro Enclaves to enable the end-to-end payment flow

Key Takeaways

• AWS sees web3 as a broad ecosystem beyond just crypto, with many decentralized applications and use cases
• Stable coins and digital asset payments are emerging as a compelling solution to address limitations of traditional payment systems
• X42 provides an open standard for internet-native, programmatic payments to enable new business models and agent-to-agent transactions
• AWS offers a comprehensive stack of services and tools to help customers build scalable, secure, and compliant agentic AI payment systems
