X-Chain
cross-chain architecture
X-Chain is short for Cross-Chain, referring to blockchain protocols, assets, or bridges designed to operate across multiple networks. In general use, it describes systems that enable interoperability between different blockchains. Specifically, in the Avalanche ecosystem, the X-Chain (Exchange Chain) is one of three built-in chains ÔÇö optimized for high-speed asset transfers and decentralized exchange of AVAX-based tokens.
Use Case: A user sends assets through the Avalanche X-Chain before bridging them to another network such as FLR for use in DeFi protocols.
Key Concepts:
- Interoperability ÔÇö Enables movement of assets across different blockchain networks.
- AVAX Architecture ÔÇö The X-Chain is distinct from the C-Chain (EVM) and P-Chain (staking).
- Bridging ÔÇö Often used as a transit path for AVAX tokens before entering other ecosystems.
- Multichain UX ÔÇö Supports seamless asset migration for DeFi, NFTs, and gaming applications.
Summary: X-Chain can mean general cross-chain capability or the specific Avalanche Exchange Chain used for AVAX transfers. In both cases, it plays a key role in unlocking blockchain interoperability, bridging assets, and facilitating fast, flexible on-chain movement across networks.
| Chain | Purpose | Example Use |
|---|---|---|
| X-Chain | Asset exchange and fast transfers (Avalanche) | Send AVAX tokens quickly across wallets or bridges |
| C-Chain | Smart contracts and DeFi (EVM-compatible) | Interact with DeFi apps or use MetaMask |
| P-Chain | Staking and validator coordination | Delegate AVAX for network security and earn yield |
