Resolution Libraries

Resolution libraries are used for interacting with NFT domain names. They can be used to retrieve payment addresses, IPFS hashes for decentralized websites, DNS records and other records types. Each Resolution Library is built and maintained by Unstoppable Domains, so updates happen automatically.


Unstoppable Domains periodically releases new domain endings, and our Resolution libraries and APIs will automatically detect and support them. Therefore, do not implement a front-end filter into your application (e.g., hard-coding domains or placing a regex filter for just .crypto, .nft, etc.). We also provide an API endpoint to query for supported domain endings.

Supported Domains for Resolution Libraries

The Resolution Libraries supports decentralized domains across two main zones:

Name Service Supported Domains
Unstoppable Name Service (UNS) .crypto, .nft, .blockchain, .bitcoin, .coin, .wallet, .888, .dao, .x
Zilliqa Name Service (ZNS) .zil
