# What is Avalanche blockchain **Avalanche** is a unique blockchain that provides **high security**, **speed** and **low-cost** fees transactions. What makes Avalanche a special network? Its mainnet is composed of three blockchains: the **X-Chain**, **C-Chain**, and **P-Chain**. Instead of having one overloaded chain, each blockchain has a specific purpose in the Avalanche ecosystem. ![](/files/GpagStzuTYDwmR2CG0ij) The X-Chain is used for **managing assets** through the Avalanche consensus protocol. Transactions on the X-Chain generate fees paid in $AVAX. That’s similar to how gas fees on Ethereum are paid in $ETH. The P-Chain **coordinates validators**. But also, it allows anyone to create a new blockchain called **subnets**. And the C-Chain is related to **smart contracts** creation which is necessary for **Decentralized** **Applications** (DAPPS) and **Non Fungible Tokens** (NFT). But also, it is **EVM** (Ethereum Virtual Machine) compatible which means anyone can deploy Ethereum smart contracts on Avalanche. --- # 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.
