The manual

Nine pages, no surprises.

Building with an AI agent? The manual is also on GitHub in plain Markdown: urbeETH/ethrome-2026-hacker-manual, one file per page plus the whole thing in a single file. Clone it next to your project, or point your tool at the raw file, so your agent knows the rules, the deadlines and the bounties.

What is at stake

One winning team.

Build what you want. One ranking, one winning team.

The ETHRome prize

One year at Urbe Hub, for the whole team.

An annual membership for every member of the winning team, up to three people, at Rome's first web3 coworking space. The same room you will have been building in all weekend.

On top of that sit $5,000 in sponsor bounties confirmed so far, and they work under completely different rules: they are chosen and paid by the sponsors alone. ETHRome has no say in who wins them and does not handle delivery.
