Avalanche (AVAX) is an open-source, highly scalable ecosystem for DeFi and enterprise blockchain solutions. Its architecture is built on three chains: X-Chain for digital assets, C-Chain for EVM-compatible smart contracts, and P-Chain for validators and subnets. Combining the speed of classical protocols with the decentralization of Nakamoto consensus, Avalanche finalizes transactions in under a second and supports millions of validators through Proof-of-Stake. AVAX, the native token, is used for fees and staking. With customizable subnets and full Ethereum toolkit support, Avalanche enables seamless creation of financial applications, tokenized assets, and purpose-built blockchains.
