Resolution Libraries

Resolution libraries are used for interacting with Web3 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.

Supported Domains for Resolution Libraries

The Resolution Libraries supports decentralized domains across two main zones:

Name Service Supported Domains
Zilliqa Name Service (ZNS) .zil
Unstoppable Name Service (UNS) .x, .polygon, .nft, .crypto, .blockchain, .bitcoin, .dao, .888, .wallet, .binanceus, .hi, .klever, .kresus, .anime, .manga, .go, .altimist, .pudgy, .unstoppable, .austin, .bitget, .pog, .clay, .witg, .metropolis, .wrkx, .secret, .raiin, .stepn
Ethereum Name Service (ENS) .eth

For the full list, check the supported TLDs endpoint.


Unstoppable Domains periodically adds new domain endings, and our Resolution libraries and APIs are designed to detect and support them automatically. This means you do not need to implement a front-end filter in your application (e.g., by hard-coding specific domains or using a regex filter for only .crypto, .nft, etc.). We also provide an API endpoint to query for supported domain endings.
