Unstoppable Domains (UD) is a company that provides blockchain-based domains. These domains are similar to traditional domain names, but they are stored on the blockchain and cannot be censored or taken down. UD recently launched an instant messaging system for owners of Web3 usernames. This means that users who have registered a .crypto, .wallet, .polygon, or other UD-registered username can now message each other across most apps that use XMTP.

XMTP is an open-source protocol that allows for decentralized messaging. It is designed to be censorship-resistant and privacy-preserving. Messages sent over XMTP are encrypted end-to-end, so only the sender and recipient can read them.

The UD messaging system is currently available in the UD iOS app and website, as well as in the Coinbase Wallet app. It will be coming soon to Lens protocol apps such as Lenster and Buttrfly. The Android version of UD will not provide messaging at launch, but it will be added in a future update.

The UD messaging system is a valuable tool for users who want to communicate securely and privately on the blockchain. It is also a way for users to connect with each other across different apps and platforms.

Here are some of the benefits of using the UD messaging system:

• Security: Messages sent over XMTP are encrypted end-to-end, so only the sender and recipient can read them. This makes it a secure way to communicate, even if one of the parties is not trustworthy.
• Privacy: The UD messaging system does not collect any personal data about its users. This means that your messages are not being tracked or stored by anyone, not even UD.
• Interoperability: The UD messaging system is built on top of XMTP, which is an open-source protocol. This means that it can be integrated with other apps and platforms, making it a more versatile communication tool.

If you are looking for a secure and private way to communicate on the blockchain, then the UD messaging system is a good option. It is easy to use and it is available across a variety of platforms.
