Terms of Service
Last Updated: October 28, 2025
Welcome to DeCA, a decentralized perpetual futures trading protocol that enables users to engage in on-chain trading and cooperative investment through smart contracts. These Terms of Service ("Terms") govern your access to and use of the DeCA protocol, including its website, user interface, smart contracts, and any related services (collectively, the "Services").
By accessing or using DeCA, you acknowledge that you have read, understood, and agreed to these Terms in full. If you do not agree, you must discontinue use of the Services immediately.
1. Nature of the Services
DeCA is a decentralized, non-custodial protocol deployed on public blockchains. It allows users to trade perpetual futures, create or participate in CoTrade Pools, and interact with smart contracts autonomously and transparently. DeCA operates without intermediaries, custodians, or centralized control. All transactions and activities are executed directly on-chain by users through their connected wallets.
DeCA provides access to an open-source interface and protocol but does not act as a broker, exchange, clearinghouse, or financial advisor.
2. Eligibility
By using DeCA, you represent and warrant that:
You are at least 18 years old or of legal age in your jurisdiction.
You have full legal capacity and authority to enter into these Terms.
You are not located in, and are not a citizen or resident of, any jurisdiction where the use of DeCA or similar decentralized trading protocols is prohibited by applicable law.
You are not subject to any sanctions or restrictions issued by any government or regulatory body.
You are solely responsible for ensuring that your use of DeCA complies with all applicable laws and regulations in your jurisdiction.
3. Non-Custodial Nature
DeCA is a non-custodial protocol. It does not hold, store, or have access to your funds, private keys, or assets. You are in full control of your wallet and are solely responsible for safeguarding your private keys, recovery phrases, and access credentials. DeCA cannot recover lost wallets or reverse on-chain transactions. All actions performed on DeCA are executed via blockchain smart contracts and are irreversible once confirmed.
4. Assumption of Risk
By using DeCA, you acknowledge that:
Trading digital assets and perpetual futures involves significant financial risk, including the potential loss of your entire investment.
Market volatility, leverage, liquidation risk, and smart contract vulnerabilities can lead to unexpected outcomes.
You interact with DeCA entirely at your own risk.
Past performance of any CoTrader, CoTrade Pool, or trading strategy does not guarantee future results.
Blockchain transactions are public, irreversible, and transparent.
You are solely responsible for your investment decisions, and DeCA, its developers, and contributors shall not be held liable for any losses arising from your participation in the protocol.
5. Prohibited Activities
When using DeCA, you agree not to engage in any of the following activities:
Violating any applicable laws, regulations, or sanctions.
Using the protocol for fraudulent, deceptive, or illegal purposes.
Attempting to hack, exploit, or disrupt smart contracts or the DeCA interface.
Engaging in wash trading, price manipulation, or other forms of market abuse.
Uploading malicious code, malware, or harmful scripts.
Accessing the Services through automated systems (bots or scrapers) except through approved APIs.
Violation of these restrictions may result in the suspension of access or reporting to competent authorities where applicable.
6. No Financial Advice
All content, analytics, and information available through DeCA are for informational and educational purposes only. DeCA does not provide investment advice, recommendations, or endorsements. Nothing in the protocol, its documentation, or its interface constitutes financial, legal, or tax advice. You are solely responsible for evaluating the suitability and risk of any trading activity you engage in.
7. Fees and Rewards
DeCA’s operations and fee structure are transparently defined within its smart contracts and documentation. All fees are applied according to on-chain logic and executed automatically without manual intervention.
DeCA charges a 10% fee on net profits generated when a CoTrade Pool is closed. This fee is deducted only when users earn profit and is distributed as follows:
5% to the Platform, supporting protocol maintenance, security, and ecosystem development
5% to the Pool Creator (Host), rewarding their role in structuring and managing the CoTrade Pool
If no profit is realized, no fee is charged.
No fees are applied on share purchases, share holding, or trading volume. Fees are only applied when profit exists, ensuring that DeCA operates under the principle that the platform succeeds only when users succeed.
All fee deductions and distributions occur on-chain, immutably and transparently, through audited smart contracts.
By using DeCA, you acknowledge and agree that these automated profit-based fee deductions will be applied upon pool settlement in accordance with the protocol logic.
8. Intellectual Property
Unless otherwise stated, all rights in the DeCA name, design, logo, website interface, and documentation belong to the DeCA team or their respective owners. You are granted a limited, non-exclusive, revocable license to use the DeCA interface and documentation for personal, non-commercial purposes. You may not reproduce, distribute, or modify DeCA’s intellectual property without prior written consent.
Open-source components of DeCA are governed by their respective licenses, which may grant broader rights subject to their specific terms.
9. Smart Contracts and Third-Party Integrations
DeCA relies on smart contracts and may integrate with third-party blockchain services such as:
Wallet connection providers (e.g., WalletConnect, MetaMask)
Oracle networks
Liquidity or data aggregators
DeCA does not control or guarantee the performance, security, or availability of any third-party services. You acknowledge that your use of such third-party components is at your own risk and subject to their own terms and policies.
10. No Warranty
DeCA is provided on an “as is” and “as available” basis, without warranties of any kind, express or implied. We do not guarantee that the protocol or its website will be uninterrupted, error-free, or secure. DeCA does not warrant that the results of using the protocol will be accurate, reliable, or profitable.
You acknowledge that blockchain technology and decentralized systems carry inherent risks, including but not limited to software bugs, exploits, and technical failures.

13. Termination
DeCA reserves the right to restrict, suspend, or terminate access to its website or interface at any time, without prior notice, if a user is found to be violating these Terms or applicable laws. Termination of website access does not affect the operation of the on-chain smart contracts, which remain autonomous and permissionless.
14. Changes to the Terms
DeCA may amend or update these Terms periodically. Any modifications will take effect immediately upon publication on the official DeCA website. Your continued use of the Services after such changes constitutes acceptance of the updated Terms. Users are responsible for reviewing these Terms regularly to stay informed of any updates.
15. Governing Law
These Terms are governed by and construed in accordance with the principles of international decentralized software law, without regard to conflict of laws rules.
