# Introduction
As the Monad ecosystem expands, users will need a convenient way to interact with dApps, protocols; and the need for an efficient means to engage with dApps and protocols becomes essential. Using cryptocurrency addresses can be cumbersome and error-prone sometimes.
This is where Nad Name Service shines.
### What is Nad Name Service ?
Nad Name Service (NNS) is a distributed, open web3 name service based on the Monad blockchain.
At its core, NNS provides mapping between human-readable names like 'salmo.nad' to machine-readable identifiers such as cryptocurrency addresses, content hashes, metadata, and more.
DApps and protocols integrated with NNS enable users to use human-readable names instead of cryptocurrency addresses , making interactions as seamless and smooth as possible.

Each name will be a NFT so that users can easily trade names on NFT marketplaces.
