Terms of Service

NexVault is non-custodial software deployed on the Nexus blockchain. It consists of four smart contracts — USDXVault, VaultGenesisBadge, ReferralRegistry, and AutoCompounder — that together form a fixed-rate USDX savings protocol.

These smart contracts are autonomous. Once deployed, they execute exactly as coded. No individual, company, entity, or organization controls the contracts or has the ability to access, move, freeze, or redirect user funds. The contracts are non-upgradeable: there is no proxy pattern, no admin upgrade key, and no mechanism to change the deployed code.

NexVault is not a bank. It is not a financial institution, investment fund, brokerage, money services business, or licensed financial services provider of any kind. NexVault is open-source software provided as-is under the MIT license. Using NexVault is equivalent to interacting directly with smart contract code on a public blockchain.

Nothing on nexvault.one, in the NexVault smart contracts, in the NexVault whitepaper, or in any NexVault communication constitutes financial, investment, legal, or tax advice. All content is provided for informational and educational purposes only.

• Users make their own independent decisions about whether to deposit funds, which tier to select, and how long to lock their capital.
• Past yield rates do not guarantee future returns. APY figures displayed on the website represent current rates, which are subject to change.
• GYDS (Global Yield Distribution System) yield rates are determined entirely by the Nexus blockchain infrastructure and are outside NexVault's control. Yield distributions may increase, decrease, or cease at any time.
• Users should consult their own financial, legal, and tax advisors before making any decisions related to the protocol.

By using NexVault, you acknowledge and voluntarily assume the following risks:

• Smart contract risk: NexVault smart contracts have undergone comprehensive internal testing with 174 passing tests across all functions, security properties, and edge cases. At initial launch, contracts have not yet been reviewed by a third-party security firm. A formal security audit is actively being funded and will be published publicly at nexvault.one/security upon completion. Users should deposit only amounts they are comfortable with until the audit report is published.
• Blockchain risk: The Nexus blockchain is a new network. Network issues, forks, consensus failures, validator downtime, or other infrastructure problems could affect the accessibility or security of deposits.
• Yield risk: GYDS distributions are variable. The yield rate may decrease or distributions may cease entirely. NexVault does not guarantee any specific return.
• Lock period risk: Locked deposits cannot be withdrawn before expiry under any circumstance. Lock periods of 1 year (LOCK_1YR), 3 years (LOCK_3YR), and 5 years (LOCK_5YR) are enforced by on-chain timestamps and cannot be overridden by anyone — including the protocol developer. The constant LOCK_IS_FINAL = true is encoded in the contract as an immutable declaration of this property.
• Regulatory risk: The legal status of DeFi protocols, stablecoins, and on-chain yield products varies by jurisdiction and is evolving rapidly. Users are solely responsible for compliance with all applicable laws and regulations in their jurisdiction.
• No insurance: Deposits in NexVault are not covered by the FDIC, SIPC, or any government or private deposit insurance scheme. There is no fund of last resort.
• Stablecoin risk: USDX is a stablecoin that maintains its peg through its own mechanism. NexVault does not guarantee the stability, redeemability, or value of USDX.

By depositing into NexVault, you acknowledge and accept all of the above risks. If you do not accept these risks, do not use the protocol.

To the maximum extent permitted by applicable law, the NexVault protocol developer, contributors, and all associated parties shall not be liable for any direct, indirect, incidental, special, consequential, or exemplary damages arising from or related to your use of the protocol.

This includes, without limitation:

• Loss of funds due to smart contract vulnerabilities, exploits, or bugs
• Loss of yield due to GYDS changes, reductions, or cessation
• Inability to withdraw funds during active lock periods
• Loss of value of USDX or any other token
• Network failures, blockchain reorganizations, or consensus issues on Nexus
• Any other protocol-related loss of any kind

Maximum aggregate liability to any user is zero. Users interact with autonomous, immutable smart contracts deployed on a public blockchain — not with a company, individual, or managed service. The protocol has no treasury, no insurance fund, and no mechanism to compensate users for losses.

At no point does NexVault, its developer, or any associated party hold, control, or have access to user funds. The distinction is absolute:

• The USDXVault smart contract is the sole custodian of deposited USDX. It is governed entirely by its immutable deployed code — not by any person, organization, or governance mechanism.
• The owner wallet (0x44e06FB3517Ee815BBA5612F783712Ac4f498ba0) has exactly one financial privilege: it can claim protocol earnings from the dev earnings function. This function enforces an on-chain invariant that the vault's USDX balance must always cover total user principal before any earnings can be withdrawn.
• The owner wallet cannot access, freeze, redirect, or withdraw user principal under any circumstances. This is not a policy — it is a mathematical constraint enforced by the smart contract code, verifiable by anyone on-chain.
• The owner address is a compile-time constant. There is no ownership transfer function. The address cannot be changed after deployment.

NexVault smart contracts are open-source software released under the MIT license. Anyone may read, fork, modify, and deploy the contract code for any purpose.

The NexVault name, the "V" logomark, the nexvault.one domain, and the website design are the intellectual property of the protocol developer. Use of the NexVault brand, name, or visual identity in connection with forked or modified contracts is prohibited without explicit written permission.

Anyone may fork the contracts. No one may represent a fork as NexVault or use NexVault branding to imply affiliation, endorsement, or continuity with the original protocol.

THE NEXVAULT PROTOCOL IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY. THIS INCLUDES, WITHOUT LIMITATION, IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.

The developer makes no representations or warranties that:

• The protocol will operate without interruption or error
• The protocol will be free from vulnerabilities or exploits
• Any specific yield rate will be achieved or maintained
• The protocol will be compatible with any particular wallet, network configuration, or jurisdiction

Users use the protocol entirely at their own risk and discretion.

These terms are governed by and construed in accordance with general principles of international commercial law, without regard to conflict of law provisions of any jurisdiction.

Any dispute, controversy, or claim arising out of or relating to these terms, or the breach, termination, or invalidity thereof, shall be settled by binding arbitration administered under internationally recognized arbitration rules. The arbitration shall be conducted in the English language.

By using the NexVault protocol, you agree to resolve any disputes individually and waive any right to participate in class action lawsuits, class-wide arbitration, or any other representative proceedings against the protocol developer or associated parties.

These terms may be updated at any time at the sole discretion of the protocol developer. Updated terms will be published at nexvault.one/terms with a revised "Last Updated" date.

Continued use of the NexVault protocol or website after the publication of updated terms constitutes your acceptance of those updated terms.

Important distinction: While these terms (a website document) can be updated, the NexVault smart contracts themselves cannot be changed after deployment. The on-chain rules — lock periods, yield formulas, access controls, and all other contract logic — are permanent and immutable regardless of any change to these terms.

NexVault is autonomous software. It does not have customer service, a support team, or a help desk.
