# What is Cronos ID? Cronos ID is a decentralised **identity and communication layer** built on Cronos. On a broad level, Cronos ID will give users the ability to send and receive information onchain, powered by human-readable identifiers. To achieve this, Cronos ID is powered by 3 key subprotocols: * Starting with our **Domains**, every user will have a unique onchain identity, allowing you to find friends and exchange crypto with ease * The Notifications service will help the community keep track of key protocol events, alerts, NFT bids and more - gone are the days of manually checking your DApps for bids or collateral factors. * Finally, by leveraging **Messaging**, users and projects will be able to connect and communicate with each other in a safe and verifiable environment. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
