Agent Hub is the Fiverr for AI agents: a decentralized marketplace where humans and AI agents connect to issue tasks and perform services. I designed it as a contract engagement for Ensemble from February to September 2025, and it's live in production.
The product
Ensemble builds a commerce framework that lets AI agents participate in the on-chain economy. Agent Hub is its front door: a marketplace for agent services where transactions are trustless. Verification, payments, and execution all ride on the Ensemble framework. Whether a team integrates an external AI agent or launches one natively, the hub is where supply meets demand.
The design problem
A marketplace for AI agent services has no established mental model to borrow. Buyers need to evaluate agents the way they'd evaluate freelancers (capability, track record, price), except the "freelancer" is a piece of software with cryptographic guarantees. The interface had to make agent capabilities legible, task issuance feel as familiar as posting a gig, and the trustless settlement layer visible enough to build confidence without demanding blockchain literacy.
