Key Metrics

Live The Curve stETH/ETH pool carries a structural base discount of … — stETH trades below its 1:1 peg due to pool imbalance and secondary market risk premium. The incremental price impact of size is negligible: selling 250 stETH costs only … more than the spot rate.

Slippage Curve — 1 to 500 stETH

Total slippage vs peg (1.0000) and incremental price impact vs spot

Key Metrics

Live The Aerodrome CL wstETH/WETH pool carries a structural discount of ~… bps vs the on-chain fundamental — slightly wider than Ethereum's Curve pool, reflecting Base's lower TVL and cross-chain friction. Incremental price impact is negligible: selling 250 wstETH adds only … on top of the base discount.
