ae-market-place

This repository will guide you through all the steps required to create an NFT MARKETPLACE AND NFT collection and mint unique NFTs on the æternity blockchain using the AEX-141 standard.

How to Deploy Fontend ae-market place

cd /frontend
npm install,
npm run start

#NFT

Extensions

The example demonstrates the usage of following extensions:

• mintable

It is planned to introduce a new extension mapped_metadata which reflects this example and defines how to deal with collection specific metadata.

Dealing with metadata

In the AEX-141 standard we aimed to be very flexible when it comes to dealing with metadata.

Example collection: ae market for ox into the Metaverse

For this example we used DALL-E 2 to generate some images based on the text

The images have been uploaded and pinned using Pinata where you can pin up to 1GB of media for free.

The NFT images of the example collection are stored under nfts/images and their filename reflect the IPFS hash which is used in the media_url of each NFT ;-)

Note:

• When creating NFT collections you (or your community) should ensure that the media is always pinned on IPFS (or other decentralized storage alternatives) either by yourself or by some 3rd party service you typicall have to pay for.
• The good thing is that the IPFS hash will always be the same as long as somebody owning the original media has it stored somewhere, uploads and pins at again on IPFS.
• The bad news is that if the media isn't pinned anymore and nobody saved the original file the NFT media cannot be fetched anymore.

Deployment & Minting nft and market place

With the following step deploying scripts you can easily test deployment on the official testnet. For mainnet almost identical steps can be executed. Of course you need some Æ to cover the transaction fees.

Create keypair and get some Æ on testnet

Check out the quick start guide to learn how to create a keypair and how to fund your account:

• https://docs.aeternity.com/aepp-sdk-js/latest/quick-start/

Alternatively just execute the create_keypair_and_fund_account.js script as follows:

node ./deploy/create_keypair_and_fund_account.js

It will print the following output to the console:

Secret key: ......... ;-)
Public key: ak_tbTs4c6akzcdqg5f9fRHUvUrww7Z93QPopQ168Dw56u4g26gz
Balance: 5000000000000000000 ættos

Deploy & Mint :-)

The deploy_and_mint.js script demonstrates how you can use the SDK programmatically to deploy and mint your NFTs on the testnet. If you run the following command, the contract will be deployed and the NFTs will be minted according to the data defined in collection_metadata.json:

SECRET_KEY=<your_secret_key> node ./deploy/deploy_and_mint.js

Alternatively you can set the env variable SECRET_KEY in your terminal and just run node ./deploy/deploy_and_mint.js.

The output then should look as follows:
