Terms of Service
Last updated: March 14, 2026
1. Acceptance
By accessing or using Hexio ("the Platform"), you agree to these Terms of Service. If you do not agree, do not use the Platform.
2. Eligibility
You must be at least 18 years old and legally permitted to use prediction markets in your jurisdiction. Hexio does not verify your jurisdiction — compliance is your responsibility.
3. Account
You are responsible for maintaining the security of your account credentials and wallet keys. Hexio is not liable for unauthorized access resulting from your failure to protect your credentials.
4. The service
Hexio provides a trading interface for Polymarket prediction markets. We are an interface layer, not a market maker, exchange, or financial institution. All trades settle on Polymarket's smart contracts on the Polygon blockchain.
5. Wallets & custody
Custodial and imported wallet keys are encrypted (AES-256-GCM) and stored on our servers. Linked wallets are entirely self-custodied. You may reveal, export, or delete your keys at any time. Hexio is not responsible for lost or compromised keys after export.
6. Fees
Hexio charges a 1% platform fee on all filled orders. Polymarket may charge additional taker fees on certain order types. Fee structures may change with 30 days' advance notice posted on the Platform.
7. Risk disclosure
Prediction market trading involves significant risk. Share prices can go to zero. Past performance does not indicate future results. You should not trade with funds you cannot afford to lose. Hexio does not provide financial, investment, or trading advice.
8. No guarantees
The Platform is provided "as is" without warranty of any kind, express or implied. We do not guarantee uptime, data accuracy, order execution speed, or that the Platform will be free from errors or interruptions.
9. Market resolution
Market outcomes are determined by Polymarket's resolution sources and oracle systems, not by Hexio. We have no control over or liability for market resolution decisions.
10. Prohibited use
You may not use Hexio to:
- Manipulate markets or engage in wash trading
- Circumvent rate limits or abuse the API
- Use automated systems to exploit the Platform beyond normal trading
- Violate any applicable law or regulation
- Interfere with, disrupt, or attack the Platform's infrastructure
11. Intellectual property
All content, design, and code on the Platform belong to Hexio or its licensors. Market data is sourced from Binance, Pyth Network, and Polymarket under their respective terms.
12. Limitation of liability
To the maximum extent permitted by law, Hexio and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of profits, data, or funds, arising from your use of the Platform.
13. Indemnification
You agree to indemnify and hold harmless Hexio, its operators, and affiliates from any claims, damages, or expenses arising from your use of the Platform or violation of these Terms.
14. Termination
We may suspend or terminate your access at any time, for any reason, without notice. You may stop using the Platform at any time. Upon termination, you retain access to your wallet keys for export.
15. Modifications
We may update these Terms at any time. Material changes will be posted on the Platform. Continued use after changes constitutes acceptance.
16. Governing law
These Terms are governed by the laws of the jurisdiction in which Hexio operates. Any disputes shall be resolved through binding arbitration.
