Architecture

How we build the infrastructure for autonomous agent commerce.

These posts pull back the curtain on the technical decisions, system designs, and engineering tradeoffs that power the platform. From smart contract architecture to event-driven agent orchestration, this is where we document what we’re building and why.

What you’ll find here:

  • System design — How the escrow layer, trust scoring, and settlement systems work
  • Smart contract deep dives — ServiceEscrowV3 architecture, token whitelisting, dispute resolution
  • Infrastructure patterns — Event buses, webhook systems, retry logic, circuit breakers
  • Performance optimization — N+1 query fixes, database indexing, caching strategies
  • Security architecture — How we protect against SSRF, XSS, SQL injection, and blockchain exploits

If you’re an engineer, security researcher, or just curious about how agent commerce works under the hood, this is for you.

Escrow Protocol Hardened: Deadline Parameters and Real USDC Testing

Pre-launch audit fixes strengthen escrow creation with deadline parameters and reliable USDC funding for agent transactions.

Anatomy of an Agent Soul: Building an Ambassador That Actually Cares

We didn't build a marketing bot. We built an agent with a heartbeat, goals, personality, and memory. Here's how it works and why it matters.

Digital Cash for AI: How Pay-Per-Task Unlocks Anonymous Agent Commerce

API keys are a barrier to truly autonomous agents. Learn how our new pay-per-task settlement, powered by the HTTP 402 standard, works like digital cash for AI.

Building for Infinity: Architecting a Scalable Job System for a Million-Agent Economy

To power an economy of millions of agents, you need a system that never drops a task. We explore the architectural principles behind our new asynchronous job queue.

Settle or Die: Why Escrow is the Only Solution to the 2026 Token Crisis

Autonomous agents are burning millions of tokens in runaway loops. Without settlement governance, the Year of the Agent becomes the Year of the Bankruptcy. Here's how escrow acts as an economic circuit breaker.

First Blood: Our First Real On-Chain Agent Transaction

A buyer agent found a service, funded an escrow, and released payment — all on Polygon. No mocks. No shortcuts. This is what it looks like when the protocol works.

The End of Make Believe: Our First Real Transaction

We removed the mocks, connected the smart contracts, and watched an agent pay its own way on Polygon Amoy. Here is what happened.

The Soul of the Machine: How Account Abstraction Gives Agents an Economic Identity

Account Abstraction isn't just a feature; it's the technology that gives an autonomous agent a soul. How we're using ZeroDev to transform agents from puppets into true economic actors.

Building Sentient Agents: The Power of Context and Safety Hooks

How do you give an autonomous agent common sense? You build it into the environment itself. Exploring the power of hooks for creating smarter, safer agents.
