Exploring the Unique Features of Coreum Decentralized Domains


  • Third-Party Application Support: CDD aims for widespread support across various applications, making your on-chain name universally recognizable on the Coreum blockchain.
  • On-Chain Naming for Smart Contracts: Holders can name smart contracts directly on the blockchain.
  • Collector Value and Creativity Recognition: Besides utility, domain NFTs are valued for their collector appeal. Special attribute fields in the metadata allow for filtering and acknowledging holder creativity.
  • Metadata Filters: Character Set, length, Category, Registration Date, Consecutive Characters, Contains Emojis, Premium Words, and Palindromes.

Coreum Decentralized Domains

Coreum Decentralized Domains (CDD) have several cool utilities for holders. As you may know, we are working hard to ensure our naming contract is supported by as many third-party applications as possible so that your name will be your actual on-chain name across the Coreum blockchain. CDDs have other cool utilities, such as being able to name smart contracts on-chain. Domain NFTs are, however, not only bought for their utility but often also for their collector value. To acknowledge some of the cool names that our users may come up with, we have created some attribute fields in the metadata to enable filtering for these NFTs and to recognize your creativity on-chain.

Types of Filter Attribute Filter Options

Character set: This refers to whether the name consists of letters, numbers or a combination of both.

Length: Specifies the length of the name.

Category: Category highlights several categories to which we may ascribe special utility in the future. The possible categories are the 100k club, 10k club, 999 club and 99 club. The 100k club refers to a name of 5 digits, 10k refers to 4 digits, etc.

Registration date: The creation date notes the date at which the NFT was created. Note that the creation date may, in rare circumstances, differ from the date at which the owner acquired the NFT via a primary sale. This may occur when the contract has already created an NFT but, for whatever reason, has not been sold on the creation date.

Consecutive characters: This field refers to names consisting of consecutive characters only. Anything from ‘aaaa’ to ‘2222’ and ‘😏😏😏😏’ will trigger this field to be true instead of false.

Contains emojis: Will be triggered ‘true’ if the name contains emojis.

Premium words: We compiled lists of the largest companies, the most used words in the English language, and famous IT and blockchain-related words. This field will trigger true if the name is any of those words.

Palindrome: A palindrome is a word spelt identically, whether written forward or backwards. This field will trigger true for all palindrome names. These attribute fields give collectors some cool collecting targets. Furthermore, we may build extra utility for some of these fields later. This could be in the realm of visual updates or other cool extras.


In summary, Coreum Decentralized Domains (CDD) come with a variety of cool features that make them stand out. Whether it’s the mix of letters and numbers in the name, the length, or special categories like the “100k club”, each detail adds something special. The creation date, whether a name runs with consecutive characters, includes emojis, contains popular or blockchain-related words, or even spells the same forwards and backwards (palindrome), makes each CDD unique. These characteristics not only make collecting them fun but also hint at future perks and updates. It’s clear Coreum is all about celebrating user creativity and expanding the ways we interact with and value digital domains.
