14-Package Monorepo: How We Structured WAIaaS for AI Agent Builders

When you're building complex AI infrastructure like WAIaaS—a Wallet-as-a-Service that lets AI agents interact with blockchains—you face a classic problem: how do you organize code that spans everything from transaction pipelines to admin UIs to MCP integrations? The answer isn't a single massive codebase, but a carefully structured monorepo that makes it easy for AI agent builders to grab exactly what they need. Why Monorepo Architecture Matters for AI Agent Infrastructure WAIaaS isn't just a wallet service—it's a complete ecosystem. AI agents need wallets, but they also need policy engines, transaction pipelines, admin interfaces, SDK integration, and connections to 14 different DeFi protocols. When your users are building autonomous agents that handle real money, every component needs to work together seamlessly. The traditional approach of separate repositories creates dependency hell. Version mismatches between the core daemon and the SDK. Breaking changes in the transaction schema
