The Agent Economy Buildathon | $20k in bounties

Build the rails the agent economy runs on. Six days. $20k in prizes.
Powered by Superteam, Hosted by Plugged

Agents are now transacting. They buy compute, data, services, and increasingly each other's work — at machine speed, in micro-amounts, with no human in the loop.
The rails this requires don't fully exist on Web2. The infrastructure being built right now — on Solana, x402, Pay.sh, and CoralOS — is the answer.
We're bringing the builders working on this into one room for six days. $10k in cash prizes, a $10k milestone-based grant from the Solana Foundation, and infrastructure credits on the table for the best builds shipped during the week.

Who's behind this
Superteam UK — The UK chapter of Superteam, the developer ecosystem programme building the next generation of founders and operators on Solana. Grants. Hackathons. Bounties. Backing serious builders globally.
Plugged — London's curated founder community. Coworking, events, partnerships, and programming built for people who ship. Home to a community of operators, founders, and engineers across AI, fintech, and frontier tech.

What to expect
→ Six days of coworking at Plugged, gated to 50 hackers
→ Family lunch every day at 12:30 — long table, communal, phones down
→ Programmed activities throughout — technical workshops, mentor office hours, commercialisation clinics, demo nights, firesides
→ Optional 24-hour lock-in Friday into Saturday for builders going hard at the bounty
→ Closing showcase + winner announced Saturday afternoon

The bounty / up to $20k + credits
Three tracks. Pick one. Ship something deployable.
⏵ Track 01 / Agents serving other agents — machine-to-machine commerce. x402 marketplaces, multi-agent services, APIs priced for agent consumption.
⏵ Track 02 / Agents serving humans — delegated commerce. Procurement, booking, payments agents working with a budget on behalf of a human.
⏵ Track 03 / Agent-accessible services — supply side. Tools, data, compute, services designed to be paid for and used by agents.
