What is the frxETH/WETH-ng Pool?
The frxETH/WETH-ng pool is Curve's next-generation implementation for trading between Frax Finance's liquid staking token (frxETH) and Wrapped Ether. The "-ng" suffix indicates it uses Curve's latest StableSwap-NG architecture.
Understanding frxETH
Frax Ether (frxETH) is Frax Finance's liquid staking solution:
- Non-Rebasing: Price appreciation instead of balance increase
- sfrxETH Companion: Stake frxETH to earn yields as sfrxETH
- Frax Ecosystem: Integrated with Frax's stablecoin suite
- Validator Diversity: Multiple validators for decentralization
frxETH targets the LST market with a unique two-token model.
StableSwap-NG Benefits
The next-generation pool offers:
- Improved oracle integration for LST pricing
- Better handling of yield-bearing asset dynamics
- Enhanced gas efficiency
- Updated mathematical model for price curves
frxETH vs sfrxETH
Understanding Frax's dual-token model:
- frxETH: Raw liquid staking token
- sfrxETH: Yield-earning staked version
This pool trades frxETH, the base token without staking rewards. Holders seeking yield should stake frxETH for sfrxETH.
Pool Dynamics
The pool handles:
- Entry/exit for frxETH positions
- Arbitrage with other ETH liquid staking tokens
- DEX aggregator integration
- Frax ecosystem trading
Yield Analysis
LPs earn trading fees from:
- Users entering/exiting frxETH positions
- Arbitrage between LST venues
- Integration with DeFi protocols
The 0.12% APY reflects trading fee income. Additional incentives may be available through Curve gauges or Frax emissions.
