Stamps FAQ

1. How do I momentarily allow location access to mint an NFT featuring my city?

If you are on Chrome, make sure you have Settings > Chrome > Location > "While Using the App" turned on. Then, refresh your screen and try again. Once you see your personalized Stamp, turn it back off. Read the full instructions for Chrome here.

If you are on Safari, make sure you have Settings > Safari > Location > "Allow" turned on. Then, refresh your screen and try again. Once you see your personalized Stamp, you can turn location access off. Read the full instructions for Safari here.

If you are on Brave, Settings > Privacy and Security > Site and Shields Settings > Location > "Sites can ask for your location." Once you see your custom Stamp, you can turn it off again. Read the full instructions for Brave here.

If none of the above works for you, you might have to turn VPN off momentarily. Else try to clean your cache, close all Stamps tabs, open a new tab, and try again.

If all above fails, join Mentaport's Telegram and let us know so we can help!

2. What data do you collect to make my Stamp?

We collect the name of the city you are currently at only after you click “‘Get your Stamp’”, and your wallet address only after you click “Connect your wallet”. We use the name of your city to generate an NFT featuring it on the Stamp art. Once you click “Mint” and confirm the transaction, the NFT will be in your wallet. If you share your Stamp on Twitter using the “Share on Twitter” button, your Twitter post will most likely show on our page carousel. And we will probably like your tweet as well :)

If you choose not to share your location, you can still mint a Stamp. Once you connect your wallet you will mint an NFT featuring the one place we know you are at: Planet Earth. And remember that you can burn NFTs in the event you decide not to have them in your wallet any longer.

3. What is Mentaport

Mentaport is a platform to create location-aware digital assets. We empower developers to set up smart contract rules linked to physical locations, and enable dynamic controls of event triggers over time.

For Stamps, we are using our own infrastructure to personalize each NFT. But you can also use Mentaport to control distribution, facilitate discovery, and gamify end-user<>NFT interactions. You can read more here and sign up for Private Beta here.
