Stellar Hacks: Agents
Agents are one of the biggest stories in tech right now, but most agents still run into the same hard stop: payments. They can reason, plan, and act — right up until they need to pay for an API call, unlock a tool, access premium data, or complete a paid task. That’s what makes this moment so interesting on Stellar. With x402 on Stellar, builders can turn ordinary HTTP requests into paid interactions using stablecoin micropayments and Soroban authorization, letting apps, services, and agents tra
About
This hackathon is about exploring what happens when agents don’t just talk — they can buy, sell, coordinate, and earn. Think agent-to-agent services, paid tools, autonomous research workflows, machine-run marketplaces, onchain paywalls, or APIs that monetize every useful call instead of hiding behind subscriptions and API keys. Machine Payments Protocol (MPP) is also pushing this frontier forward with machine-to-machine payment flows built for paid resources, microtransactions, and programmable access, and Stellar builders can also explore the experimental stellar-mpp-sdk for MPP-style flows on Stellar. Stellar is a particularly strong place to build for this shift. It gives developers fast settlement, very low transaction costs, strong stablecoin infrastructure, and programmable guardrails through contract accounts and spending policies. In other words: the rails are finally here for software that can act economically, not just conversationally. The opportunity in this hackathon is to build the kinds of products that feel obvious in hindsight — apps, agents, and services that make the internet more programmable, more open, and more native to payments.
