: (Optional) URL of the website where the collection is going to be sold. payout_address
:(Mandatory) Wallet address that is going to receive the payments of the NFT sale. This should be the wallet address of the seller. policy
: (Mandatory) Policy configuration for every NFT in the collection. When you create a new collection we do several steps in the background; we create a new key pair (public verification key/private signing key), a policy script and the policy id. Then during the sale process, all the tokens are minted with the same policy script and the policy id is attached permanently to the NFT. lock
: (Mandatory) true
| false
Defines if the policy will be locked or not. If you select false
then you are not required to choose a date and time to lock the policy, therefore the policy will be open and you can be minting NFTs under this policy forever. If you set this parameter to true
then you have to specify a locktime
date. locktime
: (Optional) Locktime date in ISO 8601 format yyyy-mm-ddThh:mm:ss[.mmm]
. It defines how long you'll be able to mint NFTs for the collection. The policy will lock after that date, and you won't be able to mint more NFTs using the same policy id (even if you use the same key). Hours and minutes are optional; if you set it to2022-02-24
, it will automatically fill it with 0s, for example, 2022-02-24T00:00:00.000Z
.metadata
: (Optional) Metadata tags for the collection. The values between < >
mean that they are tags. A tag is simply a variable that we will evaluate its value when you mint the NFT. You can use the metadata tag to define common attributes shared by all the NFTs in the collection, like the name, copyright, date issued, artist name, social media links, etc. Using metadata tags is not mandatory because you can define all the attributes while creating the individual NFTs. asset_name
: (Mandatory) Metadata tag for the NFT asset name.name
: (Mandatory) Metadata tag for the NFT name.description
: (Optional) Metadata tag for the NFT description.media_type
: (Optional) Metadata tag for the media type.files

: (Optional) Custom attributes or traits for an NFT. You can create 2 types of attributes, fixed or variables. "Ticker":"TANGO"
. Other fixed attributes can be artist name, project name, Twitter, Discord, copyright etc. < accessory>
, then every NFT will have the key accessory, and you'll have to define a tag and provide its value during the NFT creation. This allows you to change the value for individual NFTs during their creation while maintaining a uniform set of attributes across the collection.policy_id
. You should post the policy id
in your website, social media or any communication channel, you use for buyers to verify the authenticity of the tokens they buy.
