Spot swaps, pool models and trade controls
Sections ↑SyncSwap routes wallet-funded token swaps through several automated pool designs. A trader chooses the assets and execution limits; a liquidity provider commits capital to a pool and receives a claim on its assets. Its published network coverage includes ZKsync Era, Linea, Scroll, Sophon and Creator Chain. Pool availability and contract versions must be checked within the chosen network.[1]
DefiLlama’s combined SyncSwap Protocol page, captured on 21 October 2026, displayed approximately US$8.93 million of rolling 30-day spot volume, US$2.51 million over seven days and US$159,090 over 24 hours. The combined parent includes the legacy and V3 components. These are token-swap values, not registered customers or unique active people; they do not establish a worldwide exchange rank.[28]
Four liquidity models
| Model | How liquidity is used | Practical distinction |
|---|---|---|
| Classic | Constant-product, two-token pools, conventionally balanced by value. | Broad pair support; execution changes with reserves.Source 3 |
| Stable | A hybrid curve concentrates liquidity near the relationship between pegged assets. | Efficient near the intended peg; a depeg remains an economic risk.Source 3 |
| Aqua | A Curve V2-derived design adjusts its liquidity concentration and pricing parameters. | Automated rebalancing differs from manually selecting a fixed range.Source 4 |
| Range / V3 | Liquidity providers select price ranges. | Capital exposure depends on the selected bounds and subsequent price movement.Source 5 |
The router can combine pool models, use intermediate tokens and split one trade across different paths. Multiple Hops and Path Splits are separately configurable. A route therefore need not be a single direct pool exchange. Disabling a routing feature changes the paths considered; it does not guarantee a better final price or deeper liquidity.[7]
Before approving a swap
| Display or control | Meaning |
|---|---|
| Quoted output | The estimated token amount includes trading fees; it depends on the pool state used for the quote. |
| Price impact | The effect of the proposed trade on its achievable price. It differs from later market movement. |
| Slippage / minimum received | Sets the minimum acceptable output. A swap that cannot satisfy it reverts rather than completing below that bound. |
| Execution | An estimate becomes a completed exchange only after successful network execution. |
Pool fees, network costs and liquidity economics
Sections ↑There is no single maker/taker tariff covering SyncSwap. Its fee system permits model defaults, individual-pool settings and different rates for opposite trading directions. The documentation’s maximum configurable fee is 10%; that is a configuration ceiling, not the normal charge. Project fee delegation and proposed token-holder discounts must be distinguished from the rate actually returned for a trade.[9]
Cost components
| Component | How it affects the transaction |
|---|---|
| Configured swap fee | Inspect the pool, direction and current route quote. A remembered rate from another pair is insufficient.Source 9 |
| Liquidity entry or exit | The Fee Manager documentation describes charges when deposits or withdrawals change the pool balance. A balanced Stable withdrawal is treated differently from a conversion through one asset.Source 11 |
| Network execution | Approval, swap and liquidity-management transactions can require separate gas payments.Source 25 |
| ZKsync Paymaster | Supported ERC-20 assets, including documented USDC/USDT examples, can pay gas. Fully sponsored swaps apply only under the relevant campaign conditions.Source 12 |
For a transparent fee illustration, the liquidity guide uses a Classic rate of 0.10%, divided into 0.07% for liquidity providers and 0.03% for the protocol. Applied hypothetically to US$20,000 of compatible fee-base value, those components are US$20, US$14 and US$6. This is the guide’s example structure, not a verified universal current pool rate; price impact, gas and asset-price changes are excluded.[10]
Suppose a fee-inclusive quote returns 1,000 USDC and the chosen slippage tolerance is 0.5%. The corresponding minimum is 995 USDC. That five-USDC allowance is an execution boundary, not an extra fee automatically charged. A tighter bound can cause a revert; a reverted transaction can still consume gas.[8]
Aqua fees can respond to pool imbalance through minimum, maximum and gamma parameters. Integrators must use the current fee-data interface for Aqua rather than assume an older single-rate query describes the entire fee calculation. The integration guide also warns that the Fee Manager address can change: obtain it from the relevant Pool Master.[4]
Wallet funding, liquidity withdrawals and bridges
Sections ↑A swap spends assets from the signing wallet through the selected contracts. Token approval and trade execution are distinct authorisations; the published router also supports permit-based approval. Confirm the spender, token, amount, recipient and network. A wallet connection by itself is not authority to spend a balance, while a previously granted allowance can remain after the browser closes.[25]
Liquidity entry and exit
| Position | Documented process | What can change |
|---|---|---|
| Classic LP tokens | Mint LP tokens when adding liquidity; burn them to redeem the underlying pair. | The redemption is a pool share, not repayment of the original quantities.Source 13 |
| Classic single-asset exit | burnSingle converts the other withdrawal component into the selected asset. | The embedded swap adds pricing and fee exposure.Source 13 |
| Aqua LP tokens | The pool exposes proportional burn and single-token burnSingle exits. | Pool state, rebalancing and the chosen withdrawal mode affect the result.Source 14 |
| Range position | The Portfolio provides remove/rebalance controls for Range positions; deployments identify a Position NFT Manager. | Check the position and displayed assets. A full current Range-specific exit walkthrough was not established.Source 23Source 6 |
For example, a hypothetical 1% pro-rata claim on a Classic pool holding 100 ETH and 200,000 USDC corresponds to 1 ETH and 2,000 USDC before applicable fees and rounding. If trading changes the reserves, the same percentage produces different quantities. Choosing a single-token exit then adds a conversion; it does not preserve the original two-asset example.[13]
The Vault reference concerns the older shared-vault design. It records ETH and WETH against a common balance, unwraps incoming WETH and can return native ETH or wrapped WETH according to the withdrawal mode. This internal bookkeeping is not a bank balance. Later deployments expressly omit the V1 vault, so its instructions should not be applied indiscriminately to V2, V2.1 or V3 positions.[15]
SyncSwap Move is documented as an Ethereum–ZKsync ERC-20 bridge, with additional bridge providers linked separately. Bridging into a network and swapping within it are different operations. An Ethereum withdrawal can require a claim step; check the source transfer, destination asset and final claim status. A listed third-party bridge has its own execution, liquidity and recovery conditions.[16]
Contract custody, administration and audit scope
Sections ↑Where control sits
| Layer | Relevant control |
|---|---|
| V1 versus later pools | The deployment page lists a V1 vault and expressly no vault for V2, V2.1 and V3.Source 6 |
| Pool registry | Pool Master registers pools and restricts which factories can create them.Source 17 |
| Configuration | Pool Master exposes changes to the Fee Manager, forwarder registry and factory whitelist. Decentralised execution does not mean every setting is fixed.Source 17 |
| Aqua parameters | The reference exposes amplification/gamma ramping values and timing. Changing parameters can alter future pool behaviour.Source 14 |
The Aqua assessment explains that V2 moved assets from the shared vault into individual pool contracts. Retaining the wallet key therefore coexists with contract custody of committed liquidity. Recovery of a browser or wallet display does not itself redeem a position; an exit still needs a valid transaction against the relevant contract.[19]
Audits inspected
| Report | Scope and limitation |
|---|---|
| Zellic, 4 May 2023 | Reviewed Classic Pool, Stable Pool and Vault at a specified repository commit. Router, front end, infrastructure and key custody were excluded. The report identified one low-impact finding.Source 18 |
| Zellic, 26 January 2024 | Examined the Aqua port of Curve twoCrypto V2. It found one medium- and one low-impact issue, and stated that the underlying Curve mathematics and full differential testing were outside or incomplete within its scope.Source 19 |
| Current security inventory | Lists further V2/Aqua and other-product reviews. This inventory does not by itself establish that all current V3 deployments have been independently reviewed.Source 20 |
An audit evaluates defined code and assumptions; it does not establish a per-customer insurance limit or compensation fund. The inspected reports do not promise reimbursement following a wallet compromise, price loss or failure outside their reviewed scope.[18]
Eligibility and territorial restrictions
Sections ↑The website terms require legal contractual capacity, no previous service suspension and lawful use in the user’s residence. They exclude Bosnia and Herzegovina, Burundi, China, DR Congo, Cuba, Ethiopia, Guinea, Guinea-Bissau, Iraq, North Korea, Libya, Mali, Nicaragua, Niger, Somalia, South Sudan, Sudan and Syria, plus specified OFAC-sanctioned jurisdictions. Representatives must have authority for an entity they use the service for.[21]
Support, unfinished transactions and records
Sections ↑The Community page links the official Discord entry point through syncswap.xyz/discord. That is an assistance route, not evidence of a telephone dealing desk, fixed response time or power to undo a confirmed transaction. For an unresolved operation, retain the chain, public wallet address and transaction hash; distinguish an unsigned request, pending transaction and confirmed failure before repeating it.[22]
Portfolio tracks token holdings, price trends and active positions across Classic, Stable, Aqua and Range pools, with links to DeBank and Zerion. This can help locate a position but is not an independently verified tax statement. Keep transaction hashes, input/output quantities, gas and LP changes across the relevant chains. A native consolidated tax certificate or complete CSV export was not established from the inspected dashboard documentation.[23]
The terms assign tax determination to users and permit partial or complete website suspension without notice. They provide individual JAMS arbitration, with intellectual-property exceptions.[21]
Legal counterparty and financial permission scope
Sections ↑The agreement names SyncSwap Labs, called the Foundation, without establishing an incorporation jurisdiction or entity-specific financial permission. A protocol contract address cannot resolve that legal-entity gap.[21]
Technical modularity explains how the service operates, rather than who carries a regulated customer obligation. The exchange overview separates pool models and replaceable components; it does not supply a financial licence or an insured cash account.[2]
Protocol versions and deployment continuity
Sections ↑V1 launched on ZKsync Era in 2023. The integration documentation describes later V2/V2.1 changes, including Aqua and protection against read-only reentrancy. It specifically warns against using V1 pools as price oracles. That limitation matters for applications building on pool prices; an available swap route does not establish suitability as collateral-pricing infrastructure.[4]
Version distinctions in the current deployment register
| Network | Documented scope |
|---|---|
| ZKsync Era | V1, V2/V2.1 and V3 components; the V3 router can route earlier pool versions. |
| Linea and Scroll | V1 and later router/Aqua components are listed; do not assume complete V3 parity. |
| Sophon and Creator Chain | V2.1 and V3 components, including Range factories and Position NFT Managers. |
The 1 January 2025 V3 announcement introduced Range pools, initially on ZKsync. It was an extension of SyncSwap’s pool family, not a separate exchange operator. Its prospective token and incentive statements are historical plans; current token status needs separate evidence.[5]

Developer access, token plans and reward displays
Sections ↑Programmatic responsibilities
| Task | Published integration method |
|---|---|
| Find candidate pools | Query the applicable Pool Master for the token pair and pool type. Different protocol versions need separate discovery. |
| Read executable inputs | Obtain reserves, amplification and current fee information before applying the pool’s own pricing algorithm. |
| Produce a quote | An output calculation describes a particular state and amount; it does not sign or execute a transaction. |
The published router code checks deadlines and minimum output and offers permit-based authorisation. These are concrete controls in that code; integrations must verify the deployed version rather than copy an address from an old example. Keeping a bot online is not the same as maintaining valid balances, approvals and transaction parameters.[25]
The SYNC token documentation still says the token has not been created and its contract address is to be announced. A proposed supply or future staking utility is therefore not an established tradable token, current fee discount or redemption promise. No active staking service is included in this profile’s structured service list on that evidence.[26]
The loyalty documentation describes non-transferable ySYNC accounting, with eligible fees contributing to an epoch reward share. The displayed points are not a withdrawable dollar balance or a guaranteed one-for-one token entitlement. Reward availability, epoch eligibility and any claim must be verified in the current programme; historical genesis and projected veSYNC descriptions do not establish a funded October 2026 payout.[27]
