Scaling Ethereum ETP Staking: Bridging Protocol Mechanics and Institutional Finance
Accelerating CX Agent Ramp-Up with an AI-Powered Case Grading Assistant
TL;DR: We built an AI-powered Case Grading Assistant that reduces trainee case review time from ~90 minutes to ~20 minutes – while maintaining human oversight and full auditability. The system uses comparison-based grading (evaluating agent work against known-good reference cases) via LLMs, minimizing hallucination risk and improving consistency at scale. Key insight – anchoring evaluations to explicit reference cases and rubrics enabled faster reviews while supporting more consistently calibrated outcomes.
Scaling Coinbase's Payout Infrastructure
TL;DR: Coinbase processes over a billion payout transactions a year across staking rewards, USDC rewards, and Coinbase One benefits. We’re sharing the evolution of our Payout Framework—from the limitations of synchronous processing to a high-throughput async architecture that handles rewards across dozens of assets with precision.
Distributed Proofs of Possession: Proving Key Ownership Without Exposing Keys
Reducing Fraud Loss With an Automated Dynamic Policy
Tl;dr: Coinbase has developed a novel, dynamic control policy that replaces static rules to automatically manage risk, resulting in superior financial loss mitigation and more efficient utilization of constrained resources.
Primitives vs. Platforms: Scaling DeFi Velocity with MagicSpend and ERC-4337
TL;DR: Building retail onchain products traditionally requires teams to manage a fragmented stack: smart wallets, bundlers, paymasters, and complex UserOperation construction. To solve this, we engineered two foundational layers: MagicSpend, an atomic onchain funding primitive that authorizes debits from Coinbase balances with revert-safe semantics and Magic Platform, an abstraction layer that codifies ERC-4337 infrastructure. Together, they reduced product shipping timelines by 3x and have processed over $1B in volume.
AI Across the Stack: Lessons from Building Invoicing
TL;DR: By leveraging a "Context-First" AI workflow, we shipped Coinbase Business Invoicing in weeks instead of months. We transitioned from manual UI mocking to code-first prototyping and used scoped repository sandboxing to enable safe, cross-stack iteration.
A Dedicated Architecture for Solana at Coinbase
Tl;dr: To meet the scaling demands of Solana, Coinbase has moved away from its legacy chain-agnostic processing model. We engineered a dedicated, high-throughput streaming architecture with parallel block processing, resulting in a 12x increase in transaction processing throughput and a 20% reduction in deposit latency.
