Agentic Commerce x402 Hackathon.

Build something that lasts past the weekend.

The brief asked for x402 wherever paying per request changes the product: agentic commerce, paid APIs, data access, DeFi tooling, real-world-asset services and tokenisation workflows. Above all, the organisers wanted teams that meant to keep building afterwards.

// Rules and criteria as published on the event page, luma.com/agentic-commerce-hack.

A $21,000+ prize pool, paid in two halves.

// Prize structure as published on the event page. The page describes the pool as nearly four times the size of the previous year's.

From a first workshop to the winners, in 36 hours.

// Agenda as published on the event page.

// Winners and prizes as announced on 7 June 2026. The jury spread the Infrastructure pool across four winners instead of three, as the rules allowed; the track total stayed at $7,000. Prizes are paid half after the hackathon and half on agreed milestones. Project descriptions are short summaries of each team's own submission.

The ecosystem behind the tracks.

Each bonus track came from a team already building on Algorand, and each asked builders to put that team's product inside an x402 flow.

Co-organiser · main tracks

The Algorand Foundation co-organised the hackathon and the whole Algorand Builders Berlin programme around it. Algorand is a Layer 1 blockchain built on Pure Proof-of-Stake, with fast finality and low fees; both main tracks required x402 on it.

Bonus track · 900 EURQ Quantoz

Also on the event page: GoPlausible, the team behind Algorand's x402 facilitator and its OpenClaw plugin (goplausible.com), and Featherless AI, serverless inference across thousands of open-source models (featherless.ai), which also gave a secret prize of $300 in AI credits.

Builders first, and mostly in Berlin.

From the registration form (n=368): 60% builders and engineers, 35% founders and 34% students — roles self-described, more than one allowed — with 42 Berlin the largest single source of students. Nearly all gave a GitHub username, and 81% confirmed they could be in the room in Berlin.

43% picked payments as an interest, against 25% for DeFi. Asked whether they were building on Algorand, more than half of those who answered were still thinking about it, and about a quarter already were.

Builders travelled in from San Francisco, Amsterdam, Barcelona, Warsaw, Czechia and Munich, alongside a strong Berlin crowd.

Check-in ran at about three in ten registrations — at the low end of the 31–40% band AI Agents Berlin sees for free events, which is the benchmark it plans against.

// Aggregate only, from the registration form and the Luma guest export of 29 July 2026; where builders came from is from the organisers' announcement of 10 June 2026. The Algorand question was answered by 310 of 368. AIB does not share individual attendee records with partners.

Where it went next.

Winning teams could earn the second half of their prize on milestones such as a launch on Algorand MainNet. The programme moved on to the Global x402 Challenge: Algorand After Hours on 10 July, then an online build-along on 25 August that took builders from a local API to a paid endpoint on MainNet.

x402 payments through Algorand's facilitator — merchants, payers, resources and networks — are public on GoPlausible's dashboard.

// The dashboard is operated by GoPlausible and provided as-is: an indicator, not a record.

Four steps to the build.

The hackathon was the last step of a funnel: learn x402, pitch an idea, prepare, then build. The ideathon's winners were fast-tracked into it.
