SyncSwap: Five Networks Change the Right Way to Swap
Short answer:SyncSwap is now a multi-network ZK-rollup DEX. Its current documentation lists five supported networks—ZKsync Era, Linea, Scroll, Sophon, and Creator Chain—so last year’s “move everything to ZKsync Era first” advice is outdated. Start on the network where your token already lives; bridge only when necessary.
Five rollups replace the zkSync-only answer
The important change is scope. SyncSwap is no longer best understood as a ZKsync Era-only exchange. As of 17 August 2026, its documented network list is precisely five: ZKsync Era, Linea, Scroll, Sophon, and Creator Chain.
That changes the first question. Do not ask, “How do I get this onto ZKsync Era?” Ask, “Which of those five networks already holds my funds?” A swap still happens within one supported network; the five-network expansion does not turn SyncSwap into an automatic cross-chain swap service.
Linea exposes why the old route wastes a step
Imagine holding USDC on Linea and wanting ETH. An older guide might tell you to bridge the USDC to ZKsync Era, then swap there. That adds a bridge, another transaction, another fee, and another opportunity to choose the wrong token or network.
The current route is simpler: connect the wallet to Linea, select the correct USDC and ETH assets, review liquidity, price impact, fee, and minimum received, then swap on Linea. If Linea lacks a usable pool for that pair, the answer is not automatically “bridge to ZKsync Era”; compare the cost and liquidity of bridging against using the market where the funds already sit.
Four pool models decide how the price is found
SyncSwap’s current DEX design uses four named pool models:
- Classic for general and volatile assets across a broad price range.
- Stable for closely related assets such as USDC and USDT, or some liquid-staking tokens.
- Aqua for high-volume pairs, with automated concentration and dynamic fees.
- Range for concentrated liquidity around chosen price bands.
Its Smart Router can compare routes through these models. That is the practical difference from a single-pool exchange: the best result may come from a multi-pool path, but only where liquidity actually exists. A supported network is not a guarantee that every token pair is tradable.
ERC-20 names the format SyncSwap can use
SyncSwap works with on-chain assets such as USDC, USDT, WETH, WBTC, and eligible liquid-staking tokens when the relevant network has a pool. The asset must be on the network selected in the wallet, and the token contract must be the intended one. “USDC” on Linea and “USDC” on ZKsync Era are different network balances.
Ethereum mainnet marks the first hard limit
SyncSwap does not directly swap an Ethereum-mainnet balance inside a rollup pool. A mainnet USDC balance must first be bridged into a supported environment. The same limit applies to assets on Base, Arbitrum, Optimism, Polygon, BNB Chain, Solana, or any other network outside the current five.
It also will not take fiat or native Bitcoin. BTC must arrive as a supported tokenized representation such as WBTC, and even then a live pool is required.
Paymaster changes the old “keep ETH for gas” rule
SyncSwap’s Paymaster and native account-abstraction support can allow gas payment in an ERC-20 token or enable gasless trading on eligible routes. That makes last year’s blanket instruction—“you must hold native ETH before every swap”—too broad. Keep a fallback for fees, however, because Paymaster availability depends on the network, wallet, transaction, and current app support.
One network decides the recommendation
If your funds are already on one of the five listed rollups and the pair has adequate liquidity, use SyncSwap on that network and avoid an unnecessary bridge. If the funds are on an unsupported chain, bridge first—or choose another exchange that operates there. The deciding difference is not the brand; it is the asset’s network and the liquidity available for the exact pair.
