NFTKEY Marketplace lets you unlock quick and easy access to digital collectibles and explore, buy and sell NFTs from different blockchains and artists.
Our marketplace supports multiple EVM based blockchains including Fantom, Harmony One, BNB Smart Chain, Avalanche, Polygon and Ethereum.
NFTs from collections supported can be listed for sale, bid on, bought and sold without any centralised servers. All of these events and actions are written on-chain for full transparency and accessibility.
The NFTKEY interface directly interacts with the NFTKEY Marketplace Smart Contract on the blockchain. All listing, buying and bidding actions are P2P transactions without involvement of any centralised services.
Our philosophy at NFTKEY is to provide a great user experience and embrace the blockchain decentralisation ethos. NFTKEY is a non-custodial marketplace, so your NFTs are never locked in a smart contract and never leave your wallet unless a buyer buys directly from you.
This means you can list on multiple 'non-custodial decentralised marketplaces' at once. We believe people should always retain full control of their own digital assets and they should remain in their own wallets.
Locking NFTs in another smart contract to be listed onto a marketplace is counter to what decentralisation is about.
NFTKEY Marketplace supports ERC721 smart contracts with the ERC721Enumerable extension.
NFTKEY aims to support in-demand EVM compatible blockchains with strong NFT communities.
We currently support the following blockchains:

Your NFTs stay in your wallet when you list them for sale on NFTKEY.
Locking NFTs in another smart contract to be listed onto a marketplace is counter to what decentralisation is about.
At NFTKEY you own your digital collectibles as they stay in your wallet until someone buys directly from you. All transactions on NFTKEY are on-chain P2P without centralised servers.

The collection's smart contract must have the ERC721Enumerable extension to be considered.
NFTKEY has a some criteria to meet in order to have a marketplace created for your collection.
We do our best to review and create marketplaces for most collections, but sometimes collection requests can be pushed down the list based on the volume of requests, incompatibility issue or a feature that we currently don't support.
- Collection is using the ERC721 token standard, and not ERC1155
- Collection is not in a shared smart contract with other collections
- Collection has the ERC721Enumerable extension (very common for collections)
- Collection's metadata and images can be crawled by NFTKEY's API without being blocked
- Collection doesn't have an unlimited total supply
- Collection doesn't have an unknown incompatibility with our marketplace
- Collection has a growing community of collectors and engaged community members
- Collection has community demand for a marketplace on NFTKEY and will list and trade
- Collection must not be a political vehicle that promotes antagonism and confrontation
- Collection must not be representative of hate speech or promote criminal activity
- Collection isn't primarily focused on financial instrumentation
- Collection must not be an intentional scam or rug-pulling money-grab
- Collection has consistent proportions/dimensions for all images in the collection

No, we currently don't have a token. If we ever did, we'd want to have a good tokenomic design that offers participatory incentive that doesn't hinder on the experience of using NFTKEY.
Creating a token is easy, but its flow on effects are sometimes more harm than good. When the time is right with more traded volume and community support, we'll be more inclined to design a token that works in a future-proof and sustainable manner, as any good token structure should.
It is our goal to share our success with our supporting community in one form or another, so stay tuned and involved in our growing ecosystem.
Listing is free. At the time an item is sold, a service fee of 2% + creator royalty of #% is deducted on the sell price. When you list an item for sale, NFTKEY shows you what will be deducted from your sell price, so you are able to price it accordingly.
It is important collection's creators please be considerate of the community and keep their creator royalty as low as possible. The default creator royalty is 2%, but they are able to change it within a limited range of 8% down to 0%.
If you feel the creator royalty is set too high for a particular collection, please reach out to the collection's team to let the creators know why they should consider to lower their fees.
If you are the assigned creator royalty receiver address owner, you can use a form we built to update the settings for your listed collection on NFTKEY.
Note: Please inform your community beforehand, if you're thinking of increasing your creator royalty percentage and be considerate of your community's voice and concerns.

The owner of the NFT needs to manually accept a bid for it be a sale.
Anyone is able to place a bid for an NFT that someone else holds, but it's always up to the owner of the NFT to accept any available bid.
Bids eventually expire depending on the duration a bidder has set and once expired will be removed from the bids section for that specific NFT.
Rarity rankings on NFTKEY are calculated based on the sum of rarity scores of each attribute of a token. The rarity score of each attribute is calculated by the statistical count of tokens bearing that attribute value vs the total amount of tokens.
On NFTKEY, by default, each attribute type has the same weighting. Some collections have stand-out attribute types which can influence collectors judgement more than others, and these stand-out attributes might be given higher weighting than others on our platform. For example, the “Type” trait, aka, Human or Super Human, might be weighted higher than “Background” and other less noticeable traits.
There are many mathematical methods for calculating rarity. Most of the rarity tools are using similar approaches to calculate ranking. However, the weighting of attribute types can vary from platform to platform, which can end up with different rankings between them.
NFTKEY has been trying our best to give the most objective scores. However, this doesn’t mean the ranking will end up exactly the same as other platforms. And we suggest people to do their own research and choose the ranking they want to reference from.
All events are emitted on-chain for each collection.
NFTKEY's marketplace smart contracts emit the following events:

}

Chainlist offers an easy way to search and add a Chain ID and Network ID to MetaMask so you can connect to the correct EVM powered blockchain.
NFTKEY currently supports NFT collections on these blockchains: Fantom, Harmony, Binance Smart Chain, Avalanche and Ethereum.
NFTKEY Marketplace's smart contract is 100% operational by on-chain transactions.
This means that even if our interface went down you could perform transactions to sell, buy, bid and list your NFTs without any centralised servers.
Decentralisation means many different things to different people. Some people see it as an ideology around anti-establishment and centralised governance.
NFTKEY primarily views decentralisation as how blockchain technology is utilised by principle of detaching as much centralised control of a technology and how people interact with each other.
Decentralisation from NFTKEY's point of view means: Peer-2-Peer (P2P) with as few intermediaries and points of failure as possible, while ownership of assets are in control of the rightful owner, where the owner can choose what they want to do with their assets at any moment.
By principle decentralisation should stand for empowering everyone to control and manage their own assets on-chain without any centralised servers.
On-chain transaction history is what makes blockchain technology decentralised. Blockchain technology was invented to record history and self-custody of your own assets, to function transparently from your own wallets without the absolute need for centralised servers to operate any P2P transactions.
We understand if our interface were to go down, most people wouldn't know how to interact with our 100% P2P on-chain smart contract, but at least the means to do so is always there.

If your collection's metadata is hosted on IPFS, but all the public IPFS hosting services fail to load it reliably, it is most likely that the link (CID) is not pinned in the IPFS network.
Here is a simple way to pin your NFT's IPFS link. It might help the IPFS links load faster through all the public IPFS hosting services.
2. Click Upload -> select CID -> Put in the CID in the input field
