[AWSReInvent2025] Scaling Customer Support, Compliance, and Productivity with Conversational AI at Coinbase
Lecturer
Joshua Smith is a Senior Solutions Architect at Amazon Web Services (AWS), specializing in financial services. He collaborates closely with major institutions to design scalable, secure cloud architectures.
Vara Maharivan serves as Director of Machine Learning and Artificial Intelligence at Coinbase, leading the company’s efforts to integrate advanced AI and machine learning capabilities across its cryptocurrency platform.
Abstract
This session examines how Coinbase, a leading cryptocurrency exchange, has deployed a unified generative AI platform built on Amazon Bedrock to transform three critical operational domains: customer support, regulatory compliance, and internal developer productivity. The presentation details the architectural approach, key AWS services leveraged, real-world performance metrics, and the strategic roadmap ahead. By combining retrieval-augmented generation (RAG), tool execution, and domain-specific agents, Coinbase has achieved substantial automation, cost efficiencies, and enhanced user experiences while maintaining rigorous security and compliance standards.
The Evolution of Generative AI in Financial Services
Joshua Smith opened the discussion by contextualizing the rapid maturation of generative AI within financial services. In 2023, early adoption centered on foundational concerns such as data trust and secure retrieval mechanisms. By 2024, the introduction of Amazon Bedrock enabled broader experimentation in areas like customer support, with focus shifting toward scalability, granular access controls, and integration with existing enterprise tools. Entering 2025, the landscape has progressed toward fully agentic, multi-agent systems capable of autonomously orchestrating complex workflows.
Smith emphasized that the primary challenge is no longer prototyping conversational interfaces but rather re-engineering entire business processes to deliver measurable impact on key performance indicators. This shift demands robust infrastructure, advanced security primitives, and operational frameworks tailored for agentic workloads.
AWS Services Enabling Production-Grade Agentic AI
Central to the discussion was Amazon Bedrock, a fully managed service providing access to leading foundation models through a unified API. Bedrock supports private model customization, guardrails for safety, cost-latency optimization, and, notably, Agent Core—a suite of capabilities designed to operationalize agents at scale.
Agent Core addresses critical production gaps: a serverless runtime supporting long-running multimodal agents (up to eight hours), checkpointing and recovery, identity management compatible with existing providers, secure token vaults, shared and private memory, tool discovery with fine-grained controls, and centralized observability combining logs, traces, and metrics. These components collectively mitigate risks highlighted in industry reports, such as escalating costs, unclear value, and insufficient security, which threaten the viability of agentic initiatives.
Coinbase’s Strategic Vision for AI Integration
Vara Maharivan outlined Coinbase’s mission to increase economic freedom through a trusted global cryptocurrency platform. The company rests on three pillars: building trust via top-tier security, enhancing accessibility through intuitive experiences, and scaling operations efficiently across more than 100 countries.
AI and machine learning have long underpinned fraud detection, risk assessment, personalization, and infrastructure scaling at Coinbase. Recent innovations include graph neural network-based risk scoring for blockchain addresses, ERC-20 scam token detection combining smart contract auditing with ML, and predictive scaling models to handle market volatility.
With the advent of large language models, Coinbase identified three high-impact generative AI domains: customer support automation, compliance process acceleration, and developer productivity enhancement.
Transforming Customer Support with Agentic Workflows
Crypto markets exhibit extreme volatility, driving unpredictable spikes in user inquiries that challenge traditional human-staffed support models. Coinbase addressed this through a unified generative AI platform granting fluid access to models and internal data via standardized interfaces.
The architecture features a virtual assistant handling routine interactions autonomously and an agent-assist tool empowering human representatives. The virtual assistant resolves straightforward cases end-to-end, while the assistive tool synthesizes real-time information from knowledge bases and tools, providing agents with contextual summaries, suggested responses, and multilingual capabilities.
Results demonstrate significant impact: approximately 65% of customer contacts are now automated, yielding nearly five million annualized employee-hour savings. Automated cases resolve in under ten minutes—contrasting sharply with up to forty minutes for human-handled escalations—dramatically improving customer satisfaction and operational efficiency.
Streamlining Compliance through AI-Augmented Investigations
Regulatory compliance in financial services demands rigorous processes such as KYC, KYB, and transaction monitoring. These workflows are labor-intensive, require exhaustive explainability, and must adapt to diverse jurisdictional requirements.
Coinbase augmented traditional ML-based risk detection models (deployed via Anyscale on AWS EKS) with generative AI. A compliance-assist tool aggregates data from internal systems and open-source intelligence, producing narrative summaries and risk signals for human reviewers.
At the core lies an autoresolution engine orchestrating holistic reviews. Upon a high-risk alert, the engine coordinates data synthesis, automated actions, human-in-the-loop feedback, and customer information requests. Final decisions—such as filing Suspicious Activity Reports—remain with human compliance officers, preserving accountability while accelerating throughput and consistency.
Boosting Developer Productivity across the SDLC
Developer efficiency emerged as another strategic priority. Coinbase provides multiple best-in-class coding assistants (e.g., Claude Code, Cursor) powered by Anthropic models via Bedrock, allowing engineers to select preferred tools.
A custom GitHub Action automates pull-request reviews: summarizing changes, generating natural-language comments, enforcing conventions, identifying testing gaps, and offering debugging guidance for CI failures. This shifts human review toward higher-value architectural concerns.
For quality assurance, an in-house UI testing tool translates natural-language test descriptions into autonomous browser actions across form factors, achieving parity with human accuracy, triple the bug-detection rate, and 86% cost reduction versus manual testing.
Quantifiable outcomes include nearly 40% of daily code being AI-generated or influenced (targeting 50%), 75,000 annual hours saved via automated PR reviews, and dramatically faster test introduction.
Future Directions and Platform Modernization
Coinbase aims to democratize agentic AI across the organization, enabling every employee to experiment and innovate. Ongoing efforts focus on modernizing existing tools and scaling enterprise-wide impact.
Agent Core features—secure deployment, robust identity management, advanced memory, and interoperability—are viewed as pivotal for the next phase of expansion.
Conclusion
The Coinbase case illustrates a mature approach to generative AI deployment: leveraging a unified platform on Amazon Bedrock to address volatility-driven operational challenges while upholding security and regulatory standards. By combining autonomous agents, human augmentation, and rigorous evaluation, the company has realized substantial automation, cost savings, and quality improvements across support, compliance, and engineering functions. As agentic systems evolve, such integrated architectures offer a blueprint for financial institutions seeking transformative efficiency without compromising trust.
