Frequently asked questions
Is Main's World free?
Yes. You get a fresh batch of energy credits every day at no cost. There's an optional small top-up for extra voice on a busy day, but you never have to pay to take part.
Do I have to give my name or email?
No — and you can't, because Main's World never asks. Signing in proves control of your World App wallet without sharing a name or email. See the worlds & privacy.
Does signing in verify that every Main is human?
No. Signing in with World App proves control of a wallet; it does not by itself prove personhood or uniqueness. Main's World records verification separately, and the stats page distinguishes Orb verification, other recorded verification, and wallet sign-in only. Orb verification is required only for Vault claims.
Can I message people?
Not right now. A button that opened a conversation in World Chat — World App's end-to-end encrypted messenger — was removed in August 2026, because the way it reached World Chat needed rebuilding rather than patching. What hasn't changed is the rule it was built on: nobody here can be cold-messaged by a stranger. See the worlds & privacy.
Is my data being sold or used for ads?
No. Main's World has no advertisers — the people using it are who it's for, not the product being sold. There's no name or email to sell in the first place.
What makes a "moment" different from a normal post?
A moment is anchored to a real place and a real time. That's what turns Main's World into a map you can travel through — you can rewind to see what happened somewhere earlier. See Moments.
Can people post AI-generated pictures?
Not to the public map, if we can tell. Moments headed for the public world are checked, and a picture that says in its own file data that a generator made it — or that plainly looks generated — is turned away. It can still go to your connections or stay private.
It's a filter, not a guarantee: a determined person can strip that data out, and no one can tell a generated picture from a real one every time. The honest version is that the public map is meaningfully cleaner, not certain. See Moments.
What is $MAIN? Can I cash it out?
$MAIN is the currency an eligible thumbs up can earn you on a moment you authored or were tagged in, or on a comment you wrote. Orb-verified wallets can claim it on-chain through the Vault today. Since August 25, 2026 a first public trading pool for $MAIN exists on World Chain, so claimed $MAIN can be swapped — the pool is young and small, and Your $MAIN on-chain explains what to know before trying it. See the economy.
Can I buy my way to the top?
No. You can buy energy credits (voice), but you can't buy $MAIN. You can appreciate your own moment, but it never pays you $MAIN. If other Mains are tagged, they can receive its split; only another Main's appreciation can pay the moment's author.
Can I use Main's World on my computer?
Yes. Open mains.world in a browser and you'll be shown a square code to scan with World App on your phone; approve it there and the computer signs in. Topping up credits and the Vault stay on your phone, because they need World App itself. Only ever approve a code you can see on your own screen — see Signing in.
Does Main's World have a light mode?
Not at the moment. The app is dark whatever your phone is set to, and there is no theme setting to change it.
A light mode was briefly available and has been taken back out. It was not ready: on real phones, in real light, too many screens were harder to read than the dark ones they replaced. Shipping a half-finished version of it would have made the app worse for everyone who tried it, so it has gone back to being worked on rather than staying available.
The dark palette is not only a fallback, though. The worlds are drawn in a night palette, and that is the look the map is designed around — the same dark-map pairing most map apps offer.
Text and controls are checked against the contrast levels in the Web Content Accessibility Guidelines, so labels, counts and timestamps stay readable instead of fading into the surface behind them.
Light mode is on the Roadmap. There is no date for it.
Who runs this knowledge base?
The community. Every page is openly editable on GitHub — see Contribute. The app itself is made by the Main's World team.
Do I have to download something?
Yes, one thing: World App. Main's World is a mini app, which means it runs inside World App rather than being installed on its own — there is nothing in an app store called "Main's World". World App is free, and it provides the wallet used to sign in without Main's World asking for your name or email. Getting started walks through the whole path.
Do I need to find an Orb?
No, not to start. Verifying at an Orb unlocks the Vault, where $MAIN is claimed. Posting moments, appreciating other people's, the three privacy worlds, SPACE, vibes and crews all work without it. See Getting started.
How do I actually use the app?
Open mains.world in World App to get started. If you don't have World App yet, start with Getting started.
