Many factors make each of us unique, and one of these is our spatial context. We want to imprint digital assets with what is relevant and meaningful to people: Our cities, culture, and communities. Show off the cities you are at!
Each Stamp is tailored to the user's spatial context at the time of interaction with the smart contract in a secure manner. Mentaport validates the user's location using our location SDK. After that, we need a way to verify that on-chain. So, our rule engine verifies that the location matches the expected location for the contract to execute securely. In this fun example, we are loosening up the security filters of the contract rules to allow anyone from anywhere in the world to mint.
Another fun fact about Stamps, taking advantage of advances in generative AI, we are using OpenAI’s DALL-E to dynamically generate the special art for each Stamp. Read more about Stamps and how Stamps use your location in this blog post.
