Widmann is direct about where the friction lies: “The biggest friction points center on the fact that most products are still built for humans, not agents. Sign-ups, logins, and manual onboarding create barriers that slow agentic commerce down.”

The rails race: x402, MPP, and the fight for the agentic stack

If AI agents are going to transact at scale, they need payment infrastructure designed for them from the ground up. Two protocols are emerging as early contenders for that role, and both will have a presence at Consensus 2026.

x402, the open payment protocol built on HTTP and championed by Coinbase, is designed to allow agents to pay for API access and digital services with stablecoins in a single, frictionless flow. Erik Reppel, x402’s founder and Head of Engineering at Coinbase, will be at Consensus making the case for why open, interoperable rails are the right foundation for the agentic economy.

MPP (Machine Payments Protocol), developed by Tempo and backed by Stripe, offers another vision for how agents can negotiate and settle payments autonomously. The presence of both protocols at the same event – in front of 15,000 developers, investors, and enterprise decision-makers -makes Consensus the de facto arena where the early standard-setting debate gets played out.

Also in the room: Stefano Bury, head of Virtuals Protocol, one of the leading platforms for deploying autonomous AI agents, and Chi Zhang, co-founder of Kite, whose team is building at the intersection of agent infrastructure and decentralized payments.

CoinDesk University: From Theory to Implementation

For attendees who want to go beyond the mainstage debates and into the mechanics of how to actually build and deploy agentic payments, CoinDesk University offers a structured, three-day curriculum that takes participants from first principles to advanced implementation -no prior crypto experience required.

Day 1 lays the foundation. Afternoon workshops walk attendees through setting up a stablecoin wallet and business dashboard with Circle, then pivot to session on compliance, followed by back-to-back workshops on using OpenClaw and x402.

Day 2 goes deeper into the stack, with sessions on building a full agentic infrastructure, managing agentic economy risks, and the increasingly urgent question of how to prove human identity in an AI-saturated world. By Day 3, the curriculum reaches masterclass territory: workshops on deploying AI trading bots with stablecoins, trading on prediction markets with autonomous agents, and a capstone Agentic Masterclass that brings the full arc together.

The format is intentionally immersive. Each day pairs hands-on workshops with mainstage sessions, networking lunches, and “No Dumb Questions” Q&A sessions.

The window is open. It won’t be open forever

Agentic commerce is not a future state. It is an early-stage present, moving faster than most industries have had time to notice. The protocols being debated at Consensus 2026 could become the rails that trillions of dollars in machine-to-machine transactions run on. The regulatory frameworks being discussed could define what’s permissible for a decade.

The people in the room at the Miami Beach Convention Center from May 5 to 7 will be the ones who had a voice in how this unfolds. Everyone else will be working with what they decided.

As AI Agents reshape commerce, and make every business an open book, companies will need to figure out what data actually needs to be kept secret – and protect it ferociously – in order to thrive.
