How We Designed a 7-Stage Transaction Pipeline for AI Agents

Your AI agent can analyze DeFi protocols, monitor gas prices, and even suggest optimal trade routes. But when it comes to actually executing that swap, it hits a wall. The problem isn't intelligence—it's infrastructure. Building reliable transaction execution for AI agents isn't just about connecting to an RPC endpoint. You need authentication, policy enforcement, gas optimization, approval workflows, and error handling. Most developers end up building custom solutions that break under edge cases or create security vulnerabilities. Why Transaction Pipelines Matter for AI Agents AI agents operate differently than humans. They might submit hundreds of transactions per hour, need to coordinate multi-step DeFi operations, or execute trades based on real-time market conditions. A simple "sign and broadcast" approach falls apart quickly when you need: Policy enforcement: Your agent shouldn't drain wallets or interact with malicious contracts Approval workflows: Some transactions need human o
