DEX Aggregator vs Single DEX Swap

A **DEX aggregator** splits orders across pools for better all-in price on large swaps. A **single DEX** trade is simpler and sometimes cheaper on small sizes when gas dominates.

Step by step

1. Check trade size

Aggregators shine on $5k+ equivalent moves with thin single pools.

2. Add gas to quote

Complex routes cost more gas—net savings must clear extra fee.

3. Set slippage

Tight slippage fails multi-hop routes; loose slippage risks MEV.

Aggregator vs single DEX

Small swaps on deep pools often do not need a router.

  • Aggregator: Better price on size; more gas; route transparency varies.
  • Single DEX: Lower gas; predictable path; may have worse price impact.

Common mistakes

  • Ignoring failed tx gas
  • Comparing spot price without gas and slippage

FAQ

Do aggregators always beat Uniswap?

Not on tiny trades where gas is the main cost.
