Unstoppable Domains supports developer integrations covering three main use cases. Those use cases are:

1. Domain resolution

2. Domain management

3. Domain reselling

In each case, it may be helpful to read through our Website API reference.

Domain resolution

Domain Resolution allows developers to translate a .crypto or .zil domain name into addresses for BTC, ETH, IPFS, and more. Domain Resolution can (and we believe, should) be used anywhere your application has a "Send to: " field.

To make domain resolution easier, we've written libraries for web, Android, and iOS.

Domain resolution libraries

• ​JavaScript resolution library​

• ​Java resolution library​

• ​Swift resolution library​

Access domain metadata directly

If you're familiar with blockchain development and would rather avoid an additional dependency in your application, you can also read domain metadata directly.

• ​Resolve .crypto without libraries​

• ​Resolve .zil without libraries​

• ​Resolving domain records​

• ​Smart contracts reference​

• ​Records reference​

Domain management

Editing domain metadata can be done manually by a direct connection with the appropriate blockchain. We strongly recommend prior experience with blockchain development before starting this type of integration.

• ​Smart contracts reference​

• ​Managing domain records​

• ​Managing domain ownership​

MyEtherWallet has implemented domain management and can be used as a reference implementation.

• ​MyEtherWallet code reference

• ​MyEtherWallet website​

Domain reselling

If you want to resell domains, use our website API.
