3.1 - Slippage & Price Impact

Two sides of the same coin. Both affect how much you receive from a swap.

Slippage is the difference between the price you see when you submit a swap and the price at which it actually executes. It occurs because the AMM curve moves as your trade executes, and other transactions may land before yours.


Slippage settings

Scenario
Recommended slippage

Stable pairs (USDH/USDC)

0.1%

Standard pairs (most tokens)

0.5% (default)

Volatile or thin liquidity pairs

1–2%

  • Too tight: transaction reverts with "slippage exceeded" — you pay gas but get nothing

  • Too loose: you may receive significantly less than expected, especially in thin markets

Slippage tolerance is a maximum you're willing to accept — it doesn't mean you'll always lose that amount. Most swaps execute near the quoted price.


Price Impact

Price impact is how much your trade moves the price of a pool. Large trades in pools with low liquidity have high price impact — meaning you receive worse execution than the market price suggests. AMM pools use a mathematical curve (x × y = k for Classic pools, or concentrated ranges

for CLAMM) — the larger your trade relative to pool reserves, the more the price moves.

Reducing price impact

  • Split your trade: break a large trade into several smaller ones over time

  • Trade through deeper hubs: route via USDH or WHYPE which typically have deeper liquidity

  • Trade smaller sizes: if the pool is thin, accept less or wait

  • Check routing: the router may find a multi-hop path with lower total impact
