How to use the NFTier rarity engine

In the following guide we will cover all of the bases when it comes to using our platform, from finding your collection, to connecting with Metamask.

NFTiers chrome extension

Our official chrome extension is availabe to download here. Once you've downloaded the extension, click the "puzzle piece" icon in the right-hand side of the browser. This will open a popover with the newly downloaded NFTier chrome extension.

Once you have the extension open for the first time, we offer two ways to access your collections. You can either enter any valid eth based address, or connect with Metamask. By connecting with Metamask, your collections will load faster, and you will be able to use the "send" feature. However, there is no requirement to do so.

Connect with a manual address

To connect with a manual address, simply paste the address you want to connect and click "connect"

Connecting to NFTier

Connect with Metamask

To connect with Metamask, do not enter anything in the input box, and instead click "Connect with metamask". Assuming you have Metamask installed, this will automatically open Metamask, and prompt you to sign a message from your wallet that allows us to verify that you are the actual owner. Once verified, you should see a loading icon kick off, at which point we will begin to load all of your collections into the extension. Please give it a few moments, and keep the popup open until the loading icon disappears.

Searching collections

You can lookup rarity from any of our supported collections in the extension by clicking the "magnifying glass" in the tabs within the popover. Once you are there, click the dropdown with the placeholder "collection name", and select the collection you want to search. Then, enter the token id of the NFT you want to find and press "search".

Finding collections

All collections can be found on our Collections page which allows you to search by Market Capitilization, chain, and more. Alternatively, you can utilize the search by any page on NFTier. To find a specific collection, look for the input box with the placeholder "Search a collection", and enter the name, or first few charecters of the collection you are looking for, for example,"Creamies" when searching for Creamies.

To search for collections from a single chain, select the input box which is labeled "chain", and select the chain you would like to filter by.

To sort by market cap, select the input box which is labeled "market cap", and select either "highest marketcap" or "lowest marketcap".

Using a rarity listing page

Before we dive into some of the features on the listing page, let's define a few terms, that may or may not be familiar to you.

Rank: The rank of an NFT indicates how rare it is versus all the other NFTs in the same collection. For example, in a collection of 10,000 NFTs, "Rank: 1", indicates #1 of 10,000 NFTs.

Tier score: The score of each NFT directly correlates with rank. The lower the score is, the higher the rank is, period. The tier score is calculated by looking at on-chain attributes for each NFT in a particular collection. At a very high level, the lower the number of NFTs that share those same attributes and values, the lower the score. Extremely rare traits (less than 1%), are also weighted on a sliding scale. The more rare the trait, the more of an impact it will have on the score after the overall score has been calculated.

Traits: Most NFTs that exist today, have what's known as a "token URI". This is typically an external url, which can be hosted anywhere, but typically uses a decentralized file system like IPFS. Inside this Token URI, are attributes that provide human-readable interpretations into what features a particular NFT has. The traits listed on our website are read from that Token URI.

Finding the rarest NFTs

By default, when you land on a collection's listing page on NFTier, the NFTs are sorted by highest ranking to lowest rankings. You can confirm this by selecting the input box that indicates "sort by", and select "most rare". This sort parameter will apply to any combination of searches you try. But, if a collection is still minting live, these rankings will probably change until the entire collection is minted.

Finding by token id

To find an NFT in the collection by its "token id", enter the id into the input box with the placeholder "token id", and press the "search" button. If the token id does not exist, or has not been minted yet, no search results will display.

Searching by traits

NFTier enables you to search by any attribute that is available on the NFTs within each collection. You can do so by selecting the input box with the placeholder "Search by attributes". Immediately, you will see a dropdown with all of the possible attributes. You can search in this box to narrow down a particular trait. For example, typing "Background", will display only the "Background" trait. Once you select a value, the other possible values in the same trait category will be disabled. To remove a trait from your search, simply press the "x" icon in the input box.

Searching by address

Searching by address is very straightforward. First, click the advanced filters button, beside the "Sort by" dropdown. Next, copy the address you want to search by and paste it into the input field labeled "search by owner address". After pressing "search" with the desired address, you should see the NFTs owned by that particular address.
