Use SushiSwap aggregation, which compares exchanges, when tokens for your trade are scattered across them. Choose SushiSwap for that search; one deep pool fits simple trades, while SushiXSwap moves tokens between blockchains. Compare the final amount received after fees, since a longer route can cost more than it saves.
SushiSwap Has Four Ways to Use Liquidity
The four choices are an aggregated swap, a single-pool route, a cross-chain swap, and providing liquidity. Liquidity means tokens available for people to trade. The first three are ways to swap; the fourth supplies tokens for those trades.
-
Aggregated swap: The Route Processor searches pools on the same blockchain, including pools on other decentralized exchanges. It fits a pair whose available tokens are spread across exchanges. It helps less when one pool already offers a strong quote.
-
Single-pool route: One pool holds both tokens and handles the whole trade. It fits a well-funded pair with enough tokens to absorb your order. It can give a poor price when your order is large compared with that pool.
-
Cross-chain swap: This moves value between blockchains, such as Ethereum and Arbitrum. It fits when the tokens you hold and want are on different chains. A same-chain route cannot make that move.
-
Providing liquidity: You deposit tokens into a pool and may earn part of its trading fees. It fits someone willing to hold a pool position, rather than make a swap. Your token balance can change as others trade, so it does not serve someone who simply wants to exchange tokens.
Aggregation Follows the Best Same-Chain Route
The Route Processor compares paths through available pools for the token pair and trade size you enter. It may use one pool directly or pass through an intermediate token, such as ETH. That second path can reach liquidity that the direct pair lacks.
Each pool changes price as a trade uses its reserves. This is price impact: a larger order usually gets a worse average price from a small pool. Routing through deeper pools can reduce that impact, but every pool used may charge a trading fee.
Say a $2,000 swap quotes 1,975 USDC through one pool and 1,988 USDC through two pools. Those figures are illustrative quoted outputs, with pool fees included. If the two-pool route costs $9 more in network fees, its $13 output advantage becomes $4.
This is the easy-to-miss test: compare what reaches your wallet, rather than counting pools or chasing the highest displayed rate. A route through more pools can be better for a large trade and worse for a small one. Enter your actual amount before judging it.
The Quote Shows the Next Step
Start by connecting a wallet and selecting the blockchain, input token, output token, and amount. The wallet needs some of that blockchain’s native token to pay gas, its transaction fee. If your tokens are on different blockchains, select the cross-chain option and check its separate transfer costs.
Before confirming a same-chain swap, inspect the route, quoted output, price impact, and network fee. Pool fees vary: a v2 pool typically charges 0.3%, while v3 fee tiers range from 0.01% to 1%. An interface fee may also apply, so use the displayed total for your pair.
Check minimum received, the fewest output tokens the trade will accept. It depends on your slippage tolerance, the price change you allow between submitting the trade and its completion. A wider setting may let a worse trade go through; a very tight one may cause it to fail.
If asked to approve a token, review the spending permission in your wallet before signing. Then review the swap itself and confirm it. For any trade size, choose the route that leaves you with the most usable tokens after its fees and network costs.
