Early Access Game NFT

Inspiration

New games often are available as early access. In this phase the game finished, but a fan community can be build and the game designer get already an income. NFTs are a good way to finance game development but also give the fans the ability to show up they founded the game.

What it does

The marketplace allows game makers deploy contracts and mint NFT Tokens. The fan community can buy the nft tokens then.

The game hextris is not part of the hackathon and just embedded into our page.

How we built it

First we cloned a marketplace called crypto boys and modified it a little bit. But in the end we decided to develop the smart contract from scratch. The frontend is built with vue framework. The smart contracts are built in solidity. Data which is generated by users like the description of deployed nft contracts are stored on ipfs using https://web3.storage.

Challenges we ran into

Sometimes there were problems to get tokens from the faucets. We needed the tokens to deploy the contract.

Accomplishments that we're proud of

We are proud that we deployed a erc721 smart contract and hosted a marketplace.

What we learned

We learned to deploy smart contracts and how to host web3 software on github pages. We played with ipfs and learned how to integrate it into web pages as the data for the contracts is stored on ipfs while the hash address of the data is stored in the contract.

What's next for the project

Next we need to give the frontend a redesign. An extra contract should be created to list all games which provide NFTs.

Connect more chains. Currently connected are:

Celo Blockchain

Demo Game Login if you own a Token: https://nft-login.github.io/nft-login-demo/celo/ Deployed Contract: https://alfajores-blockscout.celo-testnet.org/address/0xBa4e569A5156C00348B89653968c2C294f80E151

Avalanche Blockchain

Demo Game Login if you own a Token: https://nft-login.github.io/nft-login-demo/avax/

Theta Blockchain

Demo Game Login if you own a Token: https://nft-login.github.io/nft-login-demo/theta/ Deployed Contract: https://testnet-explorer.thetatoken.org/account/0x8fb36197889f23e76e68e3fd57c6063a21dde897

It was very hard to get TFuel to deploy the contract as there is no faucet for the testnet. We tried to deploy to the Mainnet by sending myself some Theta from Binance. But truffle told me it needs 0 Theta but X TFuel. We could not find out where to get TFuel. But thanks to the community at discord and the theta team we got enough TFuel on the Testnet to deploy the contract.

OKEx Blockchain

Visit https://nft-login.github.io/nft-login-marketplace/okt/, login to your metamask and buy a token.

You can test you own this token by visiting https://nft-login.github.io/nft-login-demo/okt/ and login by signing the message with your account that owns the token.

Heco Blockchain

Visit https://nft-login.github.io/nft-login-marketplace/heco/, login to your metamask and buy a token. Also hosted on 4everland https://market.nft-login.net/ and https://nft-login-marketplace.4everland.app/ .

You can test you own this token by visiting https://nft-login.github.io/nft-login-demo/heco/ and login by signing the message with your account that owns the token. Alternatively you can test it on 4everland https://heco-nft-login-demo.4everland.app.

Lisk Blockchain

See the video for the Lisk Blockchain here:

We did not finish, as we struggled in the beginning. We planned to host the blockchain in docker container, but we had problems to change the host which allows anyone to connect, not only localhost. Thanks to the community in discord that really helped to find the way to do it. The documentation was good, which helped to understand how the framework works. Nevertheless we could not finish. In the end in this video, you see our frontend hosted on github https://nft-login.github.io/nft-login-marketplace/lisk/?account=lsktrqzuehzhmh4senwdwz3bo2rtqenfuujegjveu&contract=http://localhost:8080/

and the backend hosted on localhost running in a container. The backend is the nft-demo https://github.com/LiskHQ/lisk-sdk-examples/tree/development/tutorials/nft rewritten in typescript. We did not change much...

The frontend is lagging in functions and just shows the available tokens and the addresses that own ist. The functionality for transfer the tokens will be built afterward.

Thanks again to the discord community of lisk.
