## Does Tetra cost anything?

Without any payment, you'll get a daily share of RA.

You'll earn when you pay attention, not dollars, but always can buy RA for a boost, and stake TETRA for wide benefits. RA is tradable on the open market for XPR, XUSDC, etc. RA sold on the market comes from those who earn it. 

## Do I need a crypto wallet? 

Really!! Get your wallet on [webauth.com](https://webauth.com/) (works best on mobiles with biometrics)

## What about Gas fees? 

**You don't need any crypto for gas**. You can transact, and complete KYC absolutely free, without needing any initial crypto. 

## Can I earn on Tetra?

Your offers can earn you XUSDC and RA if you decide to charge, or you put up  your USDC or RA to incentivive offers. 

Beyond Tetra, these connections can lead to newly-paying customers for your existing platforms. We want to connect and help your existing offers shine. 

## What does Tetra mean?

**Tetra means four.** You'll see this numerology throughout the project. Our logo features a tetrahedron in a lager tetrahedron from a top-down view.

## What is the app like?

Tetra's UI hasn't been released. We can say some displays will be map-based. While the UI is still a secret, you can get an idea of the feel of a crypto map in this [demo of Tetra's predecessor](https://www.youtube.com/watch?v=RHvhFdtzNmQ).
