# What it is

Discover NFT Arena!

## NFT based PVP Trading Card Games

NFT Arena is collection of competitive TCGs that allow you to use your NFTs as game assets, and to win NFTs from your opponents. 

The first game released will be announced soon.

Each card in the game is tied to a unique NFT staked on our smart contract, and winning (or losing) a card in-game means obtaining or losing an NFT on-chain.

### Gas Optimized

NFT Arena runs as a hybrid between a mobile application on your device, and a smart contract that will be deployed on the Ethereum blockchain (we are strongly interested in going multichain asap).

Gas costs only apply to adding/removing NFTs from the game, not to playing the game itself.

### What is an NFT?

A non-fungible token (NFT) is a unit of data stored on a digital ledger, called a blockchain, that certifies a digital asset to be unique and therefore not interchangeable. NFTs can be used to represent items such as: 

* Images
* Videos & audio
* Other types of digital files

NFTs are tracked on public blockchains to provide the bearer with a proof of ownership that is separate from copyright.
