Analytical Proof & Invariants

Machine Precision
Governing Mathematical Formula:
Price Impact (%) ≈ Trade Size / (2 · Pool Reserves) | Min Received = Quoted Amount · (1 - Slippage % / 100)

Step-by-Step Mathematical Derivation

1
Constant Product Price Shift

In x · y = k pools, trading Δx shifts the spot price. Price Impact = Δx / (x + Δx) = $25,000 / ($500,000 + $25,000) = 4.76%.

2
Slippage Tolerance Protection

With 0.5% slippage tolerance, the transaction reverts if executed price drops more than 0.5% below the simulated quote.

3
MEV Sandwich Exploitation Risk

Setting a high slippage tolerance (e.g. 2%+) on a large order allows MEV searchers to front-run and back-run your swap, extracting the entire slippage tolerance as risk-free profit.

Frequently Asked Questions

What is the difference between Price Impact and Slippage? +
Price impact is the mathematically unavoidable price movement caused by your own trade size relative to pool liquidity reserves. Slippage is the external price movement caused by other traders or MEV bots between the time you submit the transaction and when it is mined into a block.
How can large traders eliminate MEV sandwich attacks? +
Route orders through DEX aggregators (1inch, CoW Swap) that split trades across multiple pools, use MEV-Blocker private RPC endpoints, or execute intent-based batch auctions.
