Motivation

Auctions can be an exciting way to sell NFT.

Suggested Solution

We would like to provide two types of auctions

1. English auctions: where the highest bid wins at the end
2. Dutch auctions, where the price falls until someone purchases.

Motivation

In the current design, the nft owner reserved the nft metadata storage fee. The new design will be changed to class owner reserved fees.
In this way, the process of nft transfer will be changed.
No need for ready_transfer, cancel_transfer, accept_transfer. You can directly transfer to the target account.

Motivation

There is zero cost for nft order trade, and it is easy for users to forge transaction records. So it is necessary to burn a certain amount of trade fee.

• Fixed renew price
• Use formulas to convert storage space into power
• Unexpected file deletion penalty

Motivation

NFTs can be programmed so that each transaction includes royalties, allowing creators to be rewarded fairly for their work online.

The fact that NFTs are created and stored on the blockchain, means they can be traded seamlessly from wallet to wallet, with royalties paid every time they move.

It's necessary to add royalties to nft instance.

Suggested Solution

pub struct InstanceDetails<AccountId, DepositBalance> {
	/// The owner of this asset.
	pub owner: AccountId,
	/// The total balance deposited for this asset class.
	pub deposit: DepositBalance,
	/// Whether the asset can be reserved or not.
	pub reserved: bool,
	/// set transfer target
	pub ready_transfer: Option<AccountId>,
+       /// charge royalty
+	pub royalty_rate: PerU16,
+	/// Royalty beneficiary
+	pub royalty_beneficiary: AccountId,
}

Motivation

Support nft with quantitiy
