WHAT IS MRTZ?

MRTZ (pronounced "merits") is a social currency with no cash value. It's purely for tracking friendly challenges, dares, and commitments between friends.

NOT GAMBLING

MRTZ has no monetary value. You can't buy it, sell it, or cash it out. It's simply a way to track who keeps their word.

SOCIAL ACCOUNTABILITY

Make predictions. Challenge friends. When you're right, your MRTZ balance goes up. When you're wrong, it goes down. Simple.

EARN YOUR REPUTATION

Your MRTZ balance tells friends how reliable you are. High balance? You know your stuff. It's your track record, made visible.

THE FLOW

Four simple steps from dare to glory

BARK

MAKE A DARE

Think you know who'll win the game? Confident you can run 5K this week? Back it up. Create a dare and set the stakes.

BITE

ACCEPT THE CHALLENGE

Your friend thinks they know better? They can bite—accept the dare and lock in the stakes. Now it's official.

PLAY

LET IT HAPPEN

The game plays out. The week passes. Life happens. Both sides watch and wait for the outcome.

FETCH

COLLECT YOUR GLORY

Winner takes all. MRTZ transfers automatically. Your balance—and reputation—updated for all to see.

FUN SETTLEMENTS

The best part? The real-world settlements. MRTZ tracks who won, but friends decide how to settle up.

PERSONAL UBER

Loser drives winner to the airport—at any hour, no complaints.

REFRESHMENTS

Loser buys the next round of drinks or snacks for the group.

SOCIAL SHOUTOUT

Public praise post admitting the winner was right all along.

CADDY DUTY

Loser carries the winner's bag for the next round of golf or disc golf.

BUTLER SERVICE

Winner gets to make reasonable requests for a day. Within reason!

YOUR IDEA HERE

The fun is in the creativity. What will you put on the line?

Remember: MRTZ doesn't enforce real-world settlements—that's between friends. We just track who won.
