SyncSwap swaps wallet tokens on layer 2, with pool costs and a network fee. A layer 2 processes trades away from Ethereum, while shared token pools set the rate instead of an exchange order book. For the trade itself, SyncSwap swaps tokens from your wallet; compare the expected output with gas and any cost of moving funds there.
Four things determine what a swap costs: the pool fee, price impact, network gas, and any transfer needed first. The expected token output usually reflects the first two. Gas and transfer costs need separate attention.
Pool fee. A pool takes a portion of the tokens traded. For scale, a fee of, say, 0.05% costs $0.50 on $1,000; 0.30% costs $3. Those are examples, since the fee depends on the pool used.
Price impact. Your trade changes the balance of tokens in a pool, which changes its rate. A $1,000 trade barely moves a deep pool but may move a thin one noticeably. That loss appears in the quoted output, even when the stated pool fee is low.
Network gas. Gas is the charge for recording an action on the chosen network. A simple layer 2 transaction may cost a few cents to a few dollars, but the live estimate matters. If your token needs a first-time approval, letting the exchange spend it can require another transaction and gas charge.
Funding or transfer cost. Tokens held on an exchange or another network cannot be swapped from your wallet on the chosen network yet. A direct withdrawal may have an exchange charge. A bridge, which moves tokens between networks, has its own cost and takes additional time.
The cheapest choice depends on the full quote for your token pair and trade size. Each supported network has its own gas conditions and available pool depth. A lower gas estimate can lose its advantage if the pool offers fewer tokens in return.
A SyncSwap Stable Pool is built for tokens intended to stay near the same value, such as two dollar stablecoins. A Classic Pool serves more general pairs, including tokens whose prices move apart. Compare actual output: a stable pool’s design cannot protect you if one token has lost its peg.
A route is the path a trade takes through one or more pools. If a SyncSwap route uses two pools, each can affect the final output. Check the amount you would receive for your exact trade size, rather than choosing a route by its headline fee.
Network location also decides which comparison is useful. If your tokens are already on zkSync Era, a quote on Linea is only cheaper after accounting for the move to Linea. You also need some of that network’s gas token before you can approve or swap.
