On-Chain Parameters

Customize these parameters for your NFT:

Metadata and Images

Below you can find the minimum metadata that you need to upload. Additional fields like external_url, attributes, and properties are optional and can be found with further description and examples in the JSON schema. You need to upload the JSON and the image so that they are accessible from everywhere. We recommend to use a web3 storage provider like Arweave. If you want to do so by code you can follow this guide.

{
  "name": "My NFT",
  "description": "An NFT on Solana",
  "image": "https://arweave.net/tx-hash",
  "attributes": []
}

Plugins

MPL Core Assets support the use of plugins at both the Collection and Asset levels. To create a Core Asset with a plugin you pass in the plugin type and its parameters into the plugins array arg during creation. You can find more information about plugins in the Plugins Overview page. In the context of NFTs like Profile Pictures the Royalties plugin is a common use case.
