Token Map

Inspiration

My first idea was to make an automatic insurance for naturals disaster , but whent talking with my father a saw that it can be very difficult , so i decided to make a cadastre on blockchain , it can be the first part of a bigger project .

What it does

It register lands on blockchain , you only need GPS coordinates and a polygon of you land is stored like a cadastre . you can tranfer your land and soon sell it and buy .

How we built it

It's build with solidity , NextJS , Tailwinds , Chainlink Any API , Google Maps API , PositionStack API , IPFS

Challenges we ran into

So many ! i was blocked every 2-3 days ! Many times i tought i will not finish , Store variable inside a smart contract (16 max) " Compilation Failed Stack too deep !" , it was the first time working with chainlinks Nodes and jobs , all members of my team left me so i had to finish alone . It was hard but a great experience .

Accomplishments that we're proud of

I proud of going to the end of this hackathon , i had the idea , made all the code , the video even the music ! I'm very tired but proud of me

What we learned

I learned that i can code a full stack DAPP alone , many things about smart contracts , tailwinds , chainlink , how to call an API from a smart contract , how to use IPFS , ERC 721 , remix ant that im a better developper that i tought .
