The problem

Builders gather.
Build. Vanish.

Money moved on trustNo proof of who's whoThe magic is lost

We make it secure, private & repeatable.

01 · Verify — privacy first

Prove you qualify.
Reveal nothing else.

Identity Gates verify your on-chain credentials before anyone gets in — you share the proof, never your wallet or your data.

Gasless via ZeroDevYour wallet stays yoursSelective disclosure

Today, verified credentials. Next, verifiable skills & richer proofs — same privacy.

02 · Match

Matched on skills.
Not followers.

Skills, shared events & verified on-chain history decide the fit — not your follower count. Swipe to find your team.

03 · Co-live

On-chain escrow.
Held by code.

Deposits sit in a smart contract on Arbitrum until checkout — then the GMX yield goes to the host, or splits evenly across every member.
