Terms of service

Poly Syncer is a copy-trading service for the Polymarket prediction-market protocol. The service mirrors trades from public Polymarket wallets to a user's own wallet through cryptographic message signatures. Poly Syncer never takes custody of user funds, never holds private keys, and never collects email addresses, names, or KYC information. These terms explain what that means in practice, and what each side agrees to when the service is used.

1. Acceptance of these terms

By connecting a wallet to Poly Syncer, signing an EIP-712 authorization, browsing the leaderboard on the free view-only tier, or paying for a Pro or Elite subscription, the user agrees to these terms in full. If a user does not agree with any part of this document, the user must not use the service. Continued use of the service after these terms are updated constitutes acceptance of the updated version.

These terms form a binding agreement between the user (the natural person or legal entity controlling the connected wallet) and Poly Syncer (the operator of the service). The agreement begins the moment the wallet is connected and continues until terminated under section 6 or section 13.

2. Eligibility

1. The user must be at least eighteen (18) years old, or the age of majority in the user's jurisdiction, whichever is greater.
2. The user must have legal capacity to enter into a binding contract.
3. The user must not be located in, ordinarily resident in, or accessing the service from a restricted jurisdiction listed in the AML and sanctions policy.
4. The user must not be a person or entity subject to economic sanctions administered by the United Nations, the United States Office of Foreign Assets Control, the European Union, the United Kingdom, or any other applicable sanctions authority.
5. The user is solely responsible for determining whether the use of prediction markets and copy-trading services is permitted under the laws of the user's jurisdiction.

3. Description of the service

Poly Syncer is execution infrastructure. The service watches public Polymarket wallets selected by the user, detects new positions on-chain, and submits matching orders from the user's own wallet. Poly Syncer does not give investment advice. The service has the following defining characteristics:

1. Non-custodial. User funds remain in the user's wallet at all times. Poly Syncer never holds, controls, or has signing authority over user assets beyond the narrowly scoped EIP-712 trade authorizations the user issues.
2. Permission-scoped. Authorizations specify maximum position size, maximum daily volume, and an expiration timestamp. The user can revoke authorizations on-chain at any time.
3. Read-then-mirror. The service reads on-chain Polymarket data, applies the user's filters and risk limits, and submits orders through a Flashbots-style private mempool to reduce front-running.
4. Best-effort execution. Latency, slippage, and partial fills are inherent to on-chain execution. Poly Syncer publishes its current end-to-end latency on the status page but does not guarantee fill prices or fill rates.

4. User responsibilities

The user is solely responsible for:

1. Securing the private keys to the connected wallet. Poly Syncer cannot recover lost keys, reverse signed transactions, or undo authorizations that have already been submitted on-chain.
2. Funding the connected wallet with sufficient USDC and POL (or the prevailing gas token) to cover trades and network fees.
3. Choosing leader wallets, categories, and risk limits. The selection of which wallets to copy is the user's decision and the user's risk.
4. Monitoring open positions and revoking authorizations when copy-trading is no longer desired.
5. Complying with all applicable laws, including tax-reporting obligations on any gains or losses arising from copy-traded positions.

5. Plans and billing

Poly Syncer is offered through three access levels described on the pricing section of the homepage:

1. Free. View-only access to the leaderboard and wallet detail pages. No payment method is required. The free tier does not include copy-trading; following wallets and running the mirror engine require a Pro or Elite subscription.
2. Pro — 299 USD per month. Up to 250 leader wallets, premium Polygon RPC routing, and access to all 25 market categories.
3. Elite — 499 USD per month. Unlimited leader wallets, priority RPC, priority support, and earliest access to new categories and features.

Subscriptions renew monthly on the same calendar day as the original purchase. Prices are quoted in US dollars and may be paid in USDC, USDT, or by card through a third-party processor. Poly Syncer may change pricing for new sign-ups at any time; existing subscribers receive at least thirty (30) days' notice before any price change applies to their renewal.

6. Cancellation and refunds

1. The user may cancel a subscription at any time from the control panel. Cancellation takes effect at the end of the current billing period. The user retains access until that period ends.
2. Poly Syncer does not pro-rate partial months. Fees already paid are non-refundable except as required by applicable law or as expressly provided in this section.
3. If a paid subscription is cancelled within seven (7) days of the first paid invoice and no copy-trading authorizations were used during that window, the user may request a full refund by contacting support.
4. Poly Syncer may suspend or terminate access immediately if the user breaches these terms, in which case no refund is owed.

7. Acceptable use

The service must not be used to:

1. Engage in market manipulation, wash trading, spoofing, or any practice that would constitute market abuse on a regulated venue.
2. Attempt to bypass the sanctions screening, geographic restrictions, or rate-limiting controls described in the AML policy.
3. Reverse-engineer, scrape at industrial scale, or otherwise extract proprietary signals or rankings produced by Poly Syncer.
4. Probe, scan, or attack the infrastructure outside the scope of a coordinated disclosure under the security policy.
5. Use the service for any illegal purpose, or in any way that infringes the rights of third parties.

8. Intellectual property

The Poly Syncer name, logo, software, documentation, leaderboard methodology, ranking signals, and aggregate analytics are the property of Poly Syncer or its licensors. Users receive a limited, non-exclusive, non-transferable, revocable license to access and use the service for the duration of their subscription, solely for the user's own copy-trading activity.

On-chain Polymarket data referenced by the service is public and is not owned by Poly Syncer. Aggregations, derived rankings, and visualisations of that data, however, are the original work of Poly Syncer and are protected by applicable copyright and database rights.

9. Disclaimers

Poly Syncer is provided on an "as is" and "as available" basis. Poly Syncer makes no warranties, express or implied, including but not limited to merchantability, fitness for a particular purpose, accuracy, or non-infringement.

1. No investment advice. Nothing on the site, in the panel, or produced by the service is investment advice, financial advice, legal advice, or tax advice. Leaderboards are informational. The decision to copy any wallet is the user's alone.
2. Prediction-market risk. Prediction markets are speculative. Positions can go to zero. Users may lose the entire amount allocated to a copied position. The full risk picture is described in the risk disclosure, which forms part of these terms by reference.
3. No execution guarantee. Network congestion, RPC outages, smart-contract bugs, and other on-chain conditions can cause delayed, partial, or failed fills. Past leader performance does not predict future copy-trade performance.
4. Third-party services. Poly Syncer depends on third-party infrastructure including Polygon RPC providers, the Polymarket protocol, and payment processors. Poly Syncer is not responsible for failures or breaches that originate with those providers.

10. Limitation of liability

To the maximum extent permitted by law, Poly Syncer, its directors, officers, employees, and contractors will not be liable for any indirect, incidental, special, consequential, or punitive damages, including lost profits, lost revenue, lost data, or trading losses, arising out of or relating to the use of or inability to use the service.

The total aggregate liability of Poly Syncer to any user for all claims, in contract, tort, or otherwise, will not exceed the greater of (a) the fees the user paid to Poly Syncer in the twelve (12) months immediately preceding the event giving rise to the claim, or (b) one hundred US dollars (USD 100).

Some jurisdictions do not allow the exclusion or limitation of certain damages. In those jurisdictions, the limitations above apply only to the extent permitted by law.

11. Indemnification

The user agrees to indemnify and hold harmless Poly Syncer and its personnel from any claim, demand, loss, liability, or expense (including reasonable legal fees) arising out of or relating to (a) the user's use of the service, (b) the user's breach of these terms, (c) the user's violation of any applicable law, or (d) the user's infringement of any third-party right.

12. Changes to these terms

Poly Syncer may update these terms from time to time. The "last reviewed" date at the top of this page reflects the most recent revision. Material changes will be announced in the changelog at least fourteen (14) days before they take effect. Users who do not agree with an update should stop using the service before that date.

13. Governing law

These terms are governed by the laws of the jurisdiction in which the operator of Poly Syncer is incorporated, without regard to its conflict-of-law principles. Any dispute arising from or connected to the service must first be raised through good-faith correspondence with the operator. If the dispute cannot be resolved informally within sixty (60) days, it will be submitted to the courts of that jurisdiction, except where mandatory consumer-protection law requires otherwise.

Nothing in this section limits any non-waivable rights a consumer may have under the laws of their place of residence.
