Why Metropolis

The onchain economy needs a metropolis. What would you build? Metropolis is a six-week sprint to build what’s next on the onchain frontier.

What you get

$250,000+

In prizes, across four tracks, a grand champion and sponsor bounties.

What to build

Four tracks

Curated tracks to build at the frontier of onchain innovation.

Fast settlement makes new financial instruments and fully onchain markets more practical.

Best fit for

Teams who have shipped a trading, lending, or market-making product before.

  • Fully onchain order books that do not need an offchain matching engine
  • Perpetuals with funding that updates every block
  • Undercollateralised lending priced on onchain credit history

Onchain rails can make financial products feel instant, programmable, and invisible to the end user.

Best fit for

Product teams who care more about a user’s first five minutes than the architecture underneath.

  • A payments app that never mentions a blockchain to the person using it
  • Subscriptions that charge by the second instead of by the month
  • Shared wallets and group spending that settle up without an intermediary

Open social graphs, programmable incentives, and fast settlement can change how communities create and capture value.

Best fit for

Teams who have grown a community, not only built one.

  • A feed where curation is paid for by the people who benefit from it
  • Ticketing and access that follows a person rather than an email address
  • Markets on cultural outcomes rather than financial ones

AI has made identity, provenance, data ownership, and agent trust urgent infrastructure problems.

Best fit for

Teams comfortable with cryptography, protocol design, or agent frameworks.

  • Passkey-native accounts using P256 and WebAuthn, with no seed phrase
  • Agent identity and reputation under ERC-8004
  • Provenance for generated media that survives re-encoding

Grand champion

$25,000 to one team, across all four tracks.
