What Does SyncSwap Cost to Swap or Add Liquidity?

SyncSwap costs depend on the pool used, the size of the trade or deposit, and the network transaction fee. For a swap, the pool fee is taken from the trade and the pool’s reserves determine how much the other token you receive. For liquidity, you supply tokens to a pool and may pay a fee if the deposit is imbalanced.

What does SyncSwap charge for a swap?

A swap can cost a pool fee, any price impact, and network gas. The pool holds reserves of two tokens and uses a pricing curve to calculate how much of the second token a trade receives. The fee reduces the amount available to that calculation; price impact comes from the trade changing the reserve ratio. A large trade against a shallow pool can move the price more than a small trade against a deep pool.

SyncSwap has Classic and Stable pools, which use different pricing curves for different kinds of pairs. A route that passes through more than one pool can encounter a fee at each step. Before signing, compare the quoted output with the amount sent and check the displayed network fee. Slippage tolerance is a limit on how far execution can move from the quote; it is not an extra fee.

If you need to compare a swap with providing liquidity, use syncswap, a decentralized exchange native to zkSync Era and other Ethereum layer 2 networks, to swap tokens or provide liquidity in classic and stable pools. The pool type matters because its curve affects how a trade uses the reserves.

How much does it cost to add liquidity?

Adding liquidity means depositing both tokens into a pool in the proportions it currently holds, then receiving a share that represents your part of the pool. The transaction has a network gas cost. The deposit may also incur a pool fee if the amounts are unbalanced, because one token is supplied in excess of the pool’s current ratio.

Think of the pool ratio as a recipe: a balanced deposit matches it, while an imbalanced one leaves the pool with too much of one ingredient. In a Classic pool, the contract applies a fee to the excess amount to account for the swap that would otherwise bring the deposit into balance. That means the total cost can depend on the pair’s current reserves as well as the amounts you provide. SyncSwap’s current pool fee is not one universal rate: the fee manager can set default and pool-specific fees, and Aqua pools can use dynamic fees.

• Pool fee: A share of each swap, set for the pool and deducted through the trade calculation.
• Price impact: The change in the pool’s exchange rate caused by your trade size relative to its reserves.
• Network gas: The cost of submitting a swap or liquidity transaction on the network.
• Deposit imbalance: An extra pool cost may apply when a liquidity deposit does not match the pool’s token ratio.

How can you estimate the total before signing?

Start with the specific pair and pool, since fees and available reserves vary. For a swap, review the quoted output and the network fee; for a deposit, check the token amounts, the pool ratio and any fee shown in the transaction details. The quote is a snapshot, so the final execution can differ if the pool changes before the transaction is processed.

SyncSwap’s cost is therefore not a single percentage that applies to every action. For most users, the practical comparison is the amount received or deposited after pool effects, plus the gas shown for that transaction. Check the token addresses and transaction details before confirming, especially when adding liquidity to a pool you have not used before.
