Everdragons2 cross-chain NFT

Inspiration

It was 2018. They had been searching for years through hundreds of dimensions when they finally saw signs of life. A dimension with only ten thousand humanoid punks and kittens growing uncontrolled. This dimension was called Ethereum.

Three years have passed since the first Everdragons arrived in Ethereum in 2018. After a strenuous Crypto Winter and a widespread pandemic, life returns stronger than ever with kittens, apes, and many other creatures.

As for the Everdragons, they are awakening from their icy slumber. The second group of Everdragons explorers, aptly named Everdragons2, are on their way to settle in nearby dimensions. Everdragons2 settled in their new dimension, Polygon, where with new technology they forged a permanent portal to their homeland.

What it does

It's a NFT: you can mint and trade it.

It's cross-chain: you can move it from a blockchain to another. For example you can mint it on Polygon, then hold it on Ethereum for extra security, and move it back to Polygon or to BSC to play games.

How we built it

Solidity ERC721 smart contract, deployed on 3 blockchains: Polygon, Ethereum, Binance Smart Chain. It uses Wormhole to transfer tokens across blockchains.
