How this service works
Estimated price impact / slippage for a WETH/USDC trade of a given USD size on Uniswap v3, from on-chain pool depth. Order-of-magnitude signal (v3 is concentrated liquidity), useful for MEV/execution bots before trading.

Returns an estimated slippage percentage and price impact for a WETH/USDC trade of the specified USD size, computed from on-chain Uniswap v3 concentrated liquidity pool depth. Provides an order-of-magnitude signal useful for pre-trade execution decisions.
Example use cases
Pre-trade slippage check for MEV bot
“I'm about to run an arbitrage — estimate the slippage and price impact for a $500,000 WETH/USDC trade on Uniswap v3 so I know if it's still profitable after execution costs.”
Large institutional swap pre-flight
“We're planning to buy $2,000,000 worth of WETH using USDC on Uniswap v3 — what's the estimated price impact and slippage I should expect from the current pool depth?”
Optimal trade size calibration
“I want to keep slippage under 0.5% — can you check what the estimated slippage would be for a $75,000 WETH/USDC trade on Uniswap v3 so I can decide whether to split the order?”
