Terms of Service & User Agreement

PLEASE READ THESE TERMS OF SERVICE AND USER AGREEMENT (THESE "TERMS") CAREFULLY. BY CONNECTING A DIGITAL WALLET, ACCESSING, BROWSING, OR USING THE INTERFACE AT POLYYARD.APP (AND ANY ASSOCIATED SUBDOMAINS, MOBILE INTERFACES, APIS, OR SMART CONTRACT ROUTERS, COLLECTIVELY THE "INTERFACE" OR "PLATFORM"), YOU ("USER," "YOU," OR "YOUR") AGREE TO BE LEGALLY BOUND BY THESE TERMS IN THEIR ENTIRETY.

IF YOU DO NOT AGREE TO THESE TERMS, DO NOT ACCESS OR USE THE INTERFACE.

---

1. Nature of the Interface (Non-Custodial Relayer & Software Only)

1.1. Pure Software & Graphical User Interface. PolyYard is an open-source, decentralized graphical user interface and communications relayer. The Interface provides web-based access, data visualization, and cryptographic message-relaying tools that interact with autonomous, public, immutable smart contracts deployed on the Polygon PoS network (Chain ID: 137) and third-party decentralized order matching systems (specifically, Polymarket's Central Limit Order Book ("Polymarket CLOB") and the Gnosis Conditional Tokens Framework ("CTF")).

1.2. No Custody of Funds. PolyYard, its founders, operators, contributors, affiliates, and agents (collectively, the "Operator," "we," "us," or "our") NEVER hold, take custody of, escrow, manage, possess, or control any digital assets, tokens, collateral, private keys, or seed phrases of any User at any point in time. All digital asset transfers, approvals, and contract executions occur directly between your self-custodial wallet, decentralized liquidity protocols, and third-party smart contracts.

1.3. No Market-Making or Counterparty Relationship. The Operator does not act as a broker, dealer, exchange, liquidity provider, clearinghouse, market maker, financial intermediary, investment adviser, commodity trading advisor, or custodian. The Operator is not a counterparty to any prediction, order, trade, swap, or position created or settled through the Interface. All trades are matched peer-to-peer or against third-party liquidity providers via the Polymarket protocol.

1.4. No Discretion or Control. The Operator has no power, ability, or authority to halt, cancel, reverse, modify, or settle transactions executed on public blockchain networks or to alter market resolution determinations established by decentralized oracles.

2. Eligibility, Prohibited Jurisdictions & Sanctions

2.1. Eligibility. You represent and warrant that you:

• Are of legal age in your jurisdiction to enter into a binding agreement (and in no event under eighteen (18) years of age);
• Possess the legal capacity, right, power, and authority to agree to these Terms;
• Understand the inherent financial, cryptographic, and technical risks associated with Web3 applications, smart contracts, and decentralized prediction markets.

2.2. Prohibited Jurisdictions (Geofencing). You are strictly prohibited from accessing, using, or interacting with the Interface if you are a citizen, resident (tax or otherwise), national of, or located in:

• The United States of America (including its territories and possessions);
• Cuba, Iran, North Korea, Syria, the Crimea region, the Donetsk People's Republic (DNR), the Luhansk People's Republic (LNR), or any other country or territory subject to comprehensive sanctions by the United States (OFAC), the United Nations Security Council, the European Union, the United Kingdom, or other applicable governmental authorities (collectively, "Sanctioned Jurisdictions");
• Any jurisdiction where the use of decentralized prediction markets, digital asset relayers, or decentralized exchanges is illegal, restricted, or requires regulatory licenses that the Operator does not hold.

2.3. Sanctions Compliance. You represent and warrant that neither you nor any beneficial owner or entity controlling you is:

• Listed on any sanctions or restricted parties list maintained by OFAC, the UN Security Council, the UK HM Treasury, or the EU;
• Intending to use the Interface to facilitate, directly or indirectly, any transaction involving a designated individual, entity, or sanctioned territory.

2.4. Anti-Circumvention & VPN Prohibition. You agree not to access the Interface through any virtual private network (VPN), proxy server, onion routing network (Tor), or other technological mechanism designed to circumvent IP-based geofencing or disguise your true geographical location. Any such circumvention constitutes a material breach of these Terms and will result in immediate termination of access.

3. User Representations, Warranties & Acknowledgments

By using the Interface, you explicitly represent, warrant, and agree that:

• Sophistication: You have sufficient knowledge and experience in financial, cryptographic, and digital asset matters to evaluate the risks and merits of using decentralized prediction markets.
• Sole Responsibility: You are solely responsible for securing your wallet credentials, private keys, seed phrases, hardware keys, and passwords. Any loss of access to your wallet is irreversible and cannot be recovered by the Operator.
• Tax Obligations: You are solely responsible for determining, reporting, collecting, and remitting any and all taxes, duties, and assessments arising from your digital asset activities conducted through the Interface.
• Regulatory Compliance: Your use of the Interface complies with all laws, rules, and regulations applicable to you in your local jurisdiction.

4. Prohibited Activities

You agree that you will not engage in, assist with, or facilitate any of the following activities:

• Market Manipulation: Wash trading, front-running, spoofing, layering, quote stuffing, pump-and-dump schemes, or any activity intended to manipulate market volume, oracle inputs, or pricing.
• Oracle Griefing & Tampering: Any attempt to exploit, corrupt, delay, front-run, or manipulate decentralized oracle resolutions (including UMA Optimistic Oracle assertions or disputes).
• Illegal Activities: Money laundering, terrorist financing, proliferation financing, sanctions evasion, illegal gambling, fraud, extortion, blackmail, or trafficking.
• Malicious Software & Attacks: Deploying viruses, malware, trojans, worms, logic bombs, or automated scripts/bots intended to degrade, disrupt, or overload the Interface infrastructure, backend relayers, or RPC nodes.
• Reverse Engineering: Decompiling, reverse engineering, or attacking the backend relayer proxies, rate limiters, or geofencing filters.

5. Relayer Operations, Fees & Dust Mitigation

5.1. Operator Markup & Relayer Fee. To sustain the technology infrastructure, hosting, and relayer operations of PolyYard, the smart contracts and order routing engine may automatically deduct a non-custodial software relayer fee (e.g., fifty basis points or 0.50%) on orders processed through the Interface.

5.2. Pull-Over-Push Accounting. You acknowledge and accept that relayer commissions are tracked via an internal smart contract accumulator (accumulatedTreasuryFees) and swept periodically by the protocol treasury. Such fees are software convenience fees for interface access and relay services, not asset management fees, brokerage commissions, or interest.

5.3. Minimum Bet Threshold ($1.00 USDC). To prevent transaction execution failures, EVM rounding anomalies, and sub-atomic token dust issues resulting from integer division on 6-decimal USDC, the Interface and smart contracts enforce a strict minimum order size of 1,000,000 base units ($1.00 USDC). Any order below this threshold will be automatically rejected.

5.4. Gas & Network Fees. You are solely responsible for paying all network transaction fees ("gas") required by the Polygon PoS network or any originating cross-chain source networks. The Operator has no control over network congestion, gas price fluctuations, or failed transactions due to insufficient gas limits.

6. Third-Party Protocols & Cross-Chain Bridging Risks

6.1. Polymarket Protocol Dependency. The Interface relies completely on Polymarket's external CLOB APIs, WebSocket data feeds, and Gnosis CTF contracts for order matching, share minting, and payouts. The Operator has no control over Polymarket's availability, API downtime, matching algorithm updates, smart contract bugs, or business cessation.

6.2. Decentralized Oracle & Resolution Risk. All market resolutions and collateral releases are governed by decentralized oracles (including the UMA Optimistic Oracle v3). The Operator does not adjudicate, verify, vote on, resolve, or reverse market outcomes. You assume all risks associated with ambiguous market criteria, disputed oracle assertions, oracle liveness failures, or malicious voter coordination.

6.3. Cross-Chain Bridge Protocols (Li.Fi / Symbiosis). Cross-chain swaps (such as bridging USDT from Tron or Binance Smart Chain into Polygon USDC) are executed via third-party decentralized bridge aggregators and intent solvers (including Li.Fi and Symbiosis). The Operator does not process, hold, bridge, or validate cross-chain funds. Any bridge failure, solver default, delayed finality, or exploit occurring on an external bridge protocol is strictly between the User and the respective bridge provider.

10.2. Arbitration Details. The seat and legal place of arbitration shall be Dubai International Financial Centre (DIFC) / Cayman Islands (or another neutral offshore jurisdiction determined by the Operator). The language of the arbitration shall be English. The number of arbitrators shall be one (1), appointed in accordance with the applicable Rules.

10.3. WAIVER OF CLASS, REPRESENTATIVE, OR CONSOLIDATED ACTIONS. ALL CLAIMS AND DISPUTES MUST BE ARBITRATED OR LITIGATED ON AN INDIVIDUAL BASIS AND NOT ON A CLASS, COLLECTIVE, REPRESENTATIVE, OR PRIVATE ATTORNEY GENERAL BASIS. YOU EXPRESSLY WAIVE ANY RIGHT TO PARTICIPATE AS A CLASS REPRESENTATIVE OR CLASS MEMBER IN ANY CLASS ACTION, COLLECTIVE ACTION, OR CONSOLIDATED PROCEEDING AGAINST THE OPERATOR.
