FraxZero Overview
FraxZero is Frax's cross-chain infrastructure that enables seamless asset movement and liquidity. Built on a robust hub-and-spoke architecture, FraxZero provides users with flexibility to interact with frxUSD and other Frax assets across 20+ blockchain networks.
Core Architecture
Hub and Spoke Model
FraxZero operates on a hub-and-spoke architecture where Fraxtal, Frax's native L1 EVM chain, serves as the central hub for all cross-chain operations. This design ensures:
- Centralized Liquidity Management: All bridged assets are routed through the Fraxtal Hub
- Efficient Asset Routing: Optimized paths between any supported chain for 1:1 cross-chain transfers
- Unified Security Model: Consistent security standards across all connected networks
Multi-Chain Asset Support
FraxZero supports 6 Frax assets across 20+ blockchain networks, including:
- frxUSD - Frax's stablecoin
- sfrxUSD - Frax's yield-bearing stablecoin
- WFRAX - Frax's wrapped governance token
- frxETH - Frax's liquid staking derivative
- sfrxETH - Frax's staked liquid staking derivative
- FPI - Frax's price index stablecoin
