These Staking Terms of Use apply to all Users who access digital asset staking functionalities through the Nebeus Platform. Please read this article carefully before activating a Staking Program.

Introduction and Scope

These Staking Terms and Conditions (“Terms”) govern the access and use of digital asset staking functionalities made available through the Nebeus platform (the “Platform”), accessible at https://nebeus.com. The Platform allows eligible Users to participate in staking services made available through the Platform and provided and operated by regulated third-party providers.

The Platform acts as a commercial interface and user access point for staking operations. All underlying technical, custody, and validator operations are performed by authorised third-party providers or group entities acting strictly in a technical or operational capacity, integrated within the group’s infrastructure layer. No direct service provision is made by the Platform itself, nor by any group entity in a service provider or validator capacity.

These Terms apply exclusively to Users who:

1. hold a valid and verified Nebeus account;
2. have successfully completed identity verification processes (KYC/KYB); and
3. initiate one or more staking operations through the Platform in accordance with these Terms and nay applicable product-specific disclosures.

Please read carefully Clause 19 regarding the Legal Notice.

Parties, Acceptance and Binding Effect

These Terms and Conditions (the “Terms”) govern the Staking Programs made available through the Nebeus platform. These Terms constitute a legally binding agreement between:

Rintral Capital S.L. (hereinafter “Capital”), a company incorporated and existing under the laws of Spain, with registered office at Carrer de la Llacuna, 11, 08005 Barcelona, Spain, Tax Identification Number (CIF) B21849609, (“Rintral” or the “Company”),

and

the individual or legal entity who registers on the Platform and accepts these Terms electronically at the time of activation of a Staking Program (the “User”).

These Terms become legally binding upon the User at the moment the User electronically accepts them through the Platform, including by activating a Staking Program or by selecting the relevant confirmation mechanism made available by the Platform.

Electronic acceptance shall have the same legal effect as a handwritten signature, to the extent permitted under applicable law.

The User represents and warrants that (i) they have full legal capacity to enter into this agreement; (ii) where acting on behalf of a legal entity, they are duly authorised to bind such entity; and (iii) they have read and understood these Terms prior to acceptance.

Definitions

For the purposes of these Terms, the following definitions shall apply:

Account Holder: a natural person or legal entity who has successfully registered and verified a Nebeus Account, has accepted the applicable terms and disclosures, and holds Eligible Assets qualifying for participation in the Staking Program.

Platform: the digital interfaces, including the website (https://nebeus.com) and any associated mobile or desktop applications, through which Users may access information and request or initiate participation in the Staking Program.

Staking Program: the set of staking functionalities made available through the Platform, enabling Users to delegate Eligible Digital Assets to regulated third‑party providers for a predetermined Staking Period in exchange for potential rewards, as defined by the applicable plan and asset.

Staked Assets: the digital assets deposited by the User and committed to a specific Staking Program. Such assets remain contractually locked and unavailable for withdrawal, transfer, pledge, or other use during the Staking Period.

Reward(s): the yield, return, or other staking-based incentive potentially earned by the User as a result of participation in the Staking Program, as determined by the relevant blockchain network or third-party provider, and credited in accordance with the selected staking plan, applicable protocol rules, and the applicable payout schedule.Rewards are only credited if the User remains staked through the applicable payout date. Where a User initiates an unstaking request prior to a scheduled payout date, no reward shall be credited for the corresponding accrual period.

Reward(s) calculation: commences on the calendar day immediately following any staking activation, balance modification, or unstaking event (the "Cycle Start Date"). Each position maintains a single active reward cycle at any given time. Any modification to the staked balance — including additional staking, partial unstaking, or full unstaking — results in a full reset of the active reward cycle, and a new Cycle Start Date is established. Rewards accrued prior to a cycle reset are not forfeited but are held internally as Pending Rewards. Pending Rewards are released and credited to the User's account solely upon the User's completion of a full, uninterrupted reward cycle following the reset event.

Pending Rewards: are retained indefinitely and do not expire. There is no limit to the number of interrupted cycles after which Pending Rewards may accumulate. All Pending Rewards remain credited to the User's account until released in accordance with these Terms.

Staking Period: the specific duration during which the Staked Assets remain locked under the relevant staking arrangement, and during which the User may not access or otherwise dispose of such assets.

Third‑Party Provider: any regulated external validator, blockchain protocol, custodian, staking infrastructure operator, or technical service provider engaged within the group’s infrastructure layer to perform staking, custody, or validation activities in connection with the Staking Program.

Eligible Assets: the digital tokens or cryptocurrencies explicitly approved and supported for staking via the Platform, including (without limitation) USDC, EUROC, and other assets that may be added from time to time and displayed within the Staking Program interface.

All other capitalised terms shall have the meaning given to them in the Nebeus General Terms of Use, unless otherwise expressly defined herein.

Eligibility and Activation

4.1. Access to the Staking Services is strictly limited to Users, whether natural persons or legal entities, who maintain a verified Nebeus Account and have successfully completed all applicable identity verification procedures in compliance with prevailing anti-money laundering (AML) and counter-terrorist financing (CFT) laws and regulations.

4.2. Eligibility requirements are as follows:

1. Individual Users must:
   1. be at least 18 years of age or of legal majority in their jurisdiction of residence;
   2. possess full legal capacity to enter into binding agreements; and
   3. complete Know Your Customer (KYC) verification through the Platform.
2. Corporate Users must:
   1. be duly incorporated and validly existing under the laws of their jurisdiction;
   2. provide valid incorporation and governance documentation; and
   3. complete Know Your Business (KYB) procedures, including the identification and verification of directors, authorised representatives, and ultimate beneficial owners.

4.3. Access to the Staking Program may be restricted, suspended, or denied to Users domiciled or resident in jurisdictions subject to international sanctions, trade restrictions, or classified as high‑risk under applicable laws or Nebeus’ internal compliance policies.

4.4. To activate a Staking Program, the User must:

1. select a supported Eligible Asset via the Platform interface;
2. specify the desired staking amount;
3. choose a lock‑up period and applicable reward structure; and
4. review and accept all program‑specific terms and disclosures, including yield estimates, payout schedules, withdrawal rules, and risk factors.

4.5. Program activation requires express acceptance through the Platform via secure electronic confirmation. Upon confirmation, the staking arrangement becomes binding for the full duration of the selected Staking Period. Each activation of a Staking Program generates a Program Confirmation (Annex I), which sets out the specific economic and operational parameters selected by the User and forms an integral part of these Terms.

4.6. During the Staking Period, Staked Assets shall remain contractually locked and inaccessible. The User may not withdraw, transfer, pledge, or otherwise utilise such assets until the expiry of the applicable period.

4.7. By initiating a staking transaction, the User expressly acknowledges that they understand the mechanics of staking and assume all associated risks, including, without limitation: market volatility, liquidity constraints, technical disruptions, validator failures, and changes in protocol rules.

4.8. Nebeus reserves the right, in its sole discretion and in compliance with applicable law, to:

1. decline or defer activation requests;
2. suspend or restrict User access to staking features; and
3. request updated identity or compliance documentation at any time.

4.9. Failure to provide requested documentation may result in temporary suspension or permanent disqualification from participation in the Staking Program.

Staking Program Description

5.1. The Staking Services accessible via the Nebeus Platform allow Users to delegate Eligible Assets for a defined period in exchange for potential staking rewards. These rewards are generated through integrations with regulated third-party infrastructure providers and validator networks operating within supported blockchain ecosystems.

5.2. Each Staking Program is characterised by a specific set of parameters, including:

1. Lock-Up Period – the duration during which the staked digital assets are contractually locked and inaccessible to the User. Assets may not be transferred, traded, withdrawn, pledged, or otherwise used until the expiry of this period;
2. Reward Rate – the projected yield or staking return, generally expressed as an annual percentage rate (APR). Rates may be fixed or variable and are subject to revision based on market conditions, validator performance, protocol changes, or technical considerations;
3. Reward Cycle and Payout Schedule — Rewards are calculated on a cycle basis. Each reward cycle begins on the calendar day following the staking activation or the most recent balance modification event. The scheduled payout date is determined at the start of each cycle and is automatically rescheduled upon any balance modification. Rewards are credited only upon completion of a full, uninterrupted reward cycle. No partial or pro-rata payout is made mid-cycle.
4. Eligible Assets – digital assets approved and supported for staking, as published on the Platform interface. These include, but are not limited to, USDC, EUROC, and other assets listed from time to time. Asset availability may vary based on jurisdiction, regulatory status, or technical integration;
5. Reward Currency – in general, staking rewards are distributed in the same currency as the staked asset. However, where applicable, alternative reward currencies may be used and will be clearly disclosed in the program terms.

5.3. All key terms and parameters of each Staking Program — including projected yield, lock-up duration, payout schedule, risk warnings, and asset eligibility — are clearly presented to the User through the Platform interface prior to activation. The User must review and expressly accept such conditions before any staking transaction becomes effective.

5.4. Staking operations conducted via the Platform are off-chain in nature and do not involve on-chain staking smart contracts. Staked Assets are held within systems operated by authorised infrastructure partners under contractual arrangements with the group. Users do not directly interact with validator nodes, and no blockchain-level delegation is initiated by the User.

5.5. The Platform operator does not guarantee the continuity, availability, or profitability of any staking return. All reward projections are indicative and subject to change. The Platform reserves the right to suspend, modify, or terminate any Staking Program at any time, with prior notice where feasible.

Asset Lock-Up and Reward Structure

6.1. By confirming participation in a Staking Program via the Platform, the User agrees to irrevocably commit the specified Eligible Assets for the full duration of the selected Lock-Up Period.

6.2. Upon activation:

1. Irrevocable Lock-Up – The Staked Assets are immediately immobilized and rendered inaccessible for the entire Staking Period. Early withdrawal, transfer, or cancellation is not permitted, unless explicitly enabled in the program-specific conditions;
2. Reward Calculation – Staking rewards are calculated based on the committed amount, reward rate, and program duration. Reward rates presented on the Platform are indicative and may be adjusted at any time due to validator performance, network dynamics, or protocol changes; Any modification to the staked balance resets the active reward cycle in full. Rewards accrued prior to such reset are retained as Pending Rewards and released only upon completion of a subsequent full, uninterrupted reward cycle by the User.
3. Staking Infrastructure – Staked Assets are allocated through institutional infrastructure partners, including regulated validators, custodians, or staking intermediaries engaged under contractual terms with the Platform operator or its affiliates. These arrangements may be off-chain or interact with blockchain-based protocols, depending on technical design;
4. Use of Delegated Assets — Without prejudice to the User's continued legal ownership of the delegated or staked crypto-assets, the User acknowledges and agrees that Rintral Capital S.L. shall have discretion, within the scope of the applicable staking program and in coordination with the Platform Operator and authorised service providers, to determine the manner, methods, and operational processes by which rewards are generated. Rintral Capital S.L. is not required to disclose or provide transparency regarding the specific internal allocation, deployment, counterparties, or operational handling of such delegated assets, provided that such use remains consistent with the applicable program parameters and does not result in a transfer of ownership of the assets to Rintral Capital S.L. The User's sole entitlement arising from participation in such programs shall be the receipt of the applicable rewards (if any) and the return of the delegated or staked assets in accordance with the relevant program terms.
5. Reward Distribution — Rewards are credited upon completion of each full reward cycle. Where a User has accumulated Pending Rewards from one or more prior interrupted cycles, such Pending Rewards shall be released and credited together with the rewards earned upon completion of the first subsequent full, uninterrupted cycle. No interim, partial, or pro-rata distribution shall be made.
6. No Governance Rights – Participation in staking does not grant the User any voting, governance, or control rights in relation to the underlying blockchain protocol or validator network.

6.3. Reward outcomes may deviate from initial projections due to rounding mechanisms, validator downtime, network errors, or technical disruptions. While best efforts are made to work with reliable providers, no guarantee of performance or continuity is provided.

Staking Period and Early Withdrawal

7.1. The duration and structure of each Staking Program depends on the applicable program type. Certain programs operate on a fixed Lock-Up Period basis, during which Staked Assets remain fully immobilized until the scheduled maturity date. Other programs operate on an open-cycle basis, under which the User may modify their staked balance at any time, subject to the reward cycle reset mechanics described in Section 3 (Definitions) and Section 6.2(b) and (e) of these Terms. The applicable program type is disclosed to the User prior to activation.

7.2. Where a fixed Lock-Up Period applies, the selected Staking Period is binding and cannot be altered once confirmed. Users are solely responsible for selecting a lock-up duration consistent with their financial strategy, liquidity needs, and risk appetite.

7.3. Where an open-cycle program applies, the User may stake additional assets, partially unstake, or fully unstake at any time. Any such balance modification will reset the active reward cycle in full, as described in Section 3. No early access restrictions apply to the staked balance itself, but rewards accrued prior to the reset will be retained as Pending Rewards and released only upon completion of a subsequent full, uninterrupted reward cycle.

7.4. In exceptional cases—such as network-wide disruptions, validator slashing events, or force majeure circumstances—the Platform operator reserves the right to suspend or terminate Staking Programs before maturity. In such cases, affected Users will be notified and advised on any remedial or compensatory measures available.

7.5. Upon conclusion of the Staking Period, both the original Staked Assets and any associated rewards shall be released and credited back to the User’s Platform Wallet. The payout currency will match the original staked asset unless otherwise specified.

7.6. The Platform disclaims liability for any loss, liquidity constraint, or missed market opportunity resulting from the User’s voluntary commitment to a fixed-duration staking arrangement.

Interest Payout and Taxes

8.1. Rewards earned through the Staking Program are distributed in accordance with the terms selected at activation. Unless otherwise specified, rewards are calculated from the applicable Cycle Start Date and credited upon completion of the full, uninterrupted reward cycle. Where a User has accumulated Pending Rewards from one or more prior interrupted cycles, such Pending Rewards are released and credited together with the rewards earned upon completion of the first subsequent full, uninterrupted cycle.

8.2. Users may choose the reward currency during onboarding, subject to technical feasibility. Reward options typically include the same asset staked (e.g., USDC, EUROC) or another equivalent digital asset, as displayed on the Platform.

8.3. All staking rewards are shown on a gross basis before taxes. In accordance with applicable tax laws, the Platform operator or its appointed agents may apply withholding tax, where required by regulation or based on User residency status.

8.4. The withholding rate and applicable tax treatment depend on the User’s country of residence, asset type, and any relevant bilateral tax treaties. Users may request documentation (e.g., Tax Withholding Certificate) to support their tax reporting.

8.5. Each User is solely responsible for reporting and fulfilling any local tax obligations arising from their participation in staking activities. The Platform does not provide tax advice and disclaims responsibility for underreporting, misreporting, or tax penalties.

8.6. Users consent to the Platform’s compliance with applicable reporting standards, including DAC7, FATCA, CRS, and other global frameworks. Data may be shared with competent tax authorities where legally required.

8.7. Tax provisions, including applicable withholding mechanisms, are further governed by Clause 33 of the General Terms of Use.

Service Fees

9.1. Service fees may apply to specific Staking Programs and are disclosed transparently on the Platform before activation.

9.2. Such fees may include, without limitation:

1. Staking Management Fees – covering infrastructure, compliance, and operational support;
2. Reward Sharing Fees – a percentage of accrued rewards retained by the Platform or its infrastructure partners;
3. Early Termination Penalties – applicable only where early redemption is contractually permitted;
4. Third-Party Costs – including validator commission, blockchain gas fees, and custody-related charges, where relevant.

9.3. The applicable annual percentage rate (APR), net of all fees, is presented clearly during activation. By confirming participation, the User authorizes the deduction of such fees from the final amounts distributed.

9.4. No retroactive or undisclosed charges shall apply. The Platform ensures all fee structures are disclosed, fixed at onboarding, and accessible within the User’s transaction history.

Risk Disclosure and Disclaimers

10.1. Staking carries inherent financial and technical risks. By joining the Staking Program, Users acknowledge and accept the following non-exhaustive risks:

1. Market Volatility – Staked assets and rewards may experience sharp fluctuations in value due to market dynamics;
2. Protocol Risks – Validator slashing, governance changes, forks, or unexpected protocol behavior may result in reward loss or principal impairment;
3. Infrastructure Risk – The Platform relies on third-party providers for validation, custody, and execution. Technical failures, custodian insolvency, or service outages may delay or impair staking operations;
4. Legal and Regulatory Risk – National or supranational regulations may affect the legality, availability, or taxation of staking services in the User’s jurisdiction;
5. Reward Uncertainty – Indicated APRs are projections, not guarantees. Performance depends on validator behavior, network congestion, and external variables;
6. Asset Lock-Up – Assets cannot be withdrawn during the Lock-Up Period, impacting liquidity planning;
7. Force Majeure – System outages, cyberattacks, or acts of God may disrupt the staking lifecycle or asset return schedule.

10.2. Users are strongly advised to perform independent risk assessments and consult financial or legal advisors before engaging in staking activities via the Platform.

Fraud Prevention and Misuse

11.1. Account Security: Users are solely responsible for safeguarding their login credentials, device access, and account integrity. Any unauthorized access or anomalous activity must be reported immediately via the Platform’s designated support channels.

11.2. Compliance Monitoring: The Platform and its infrastructure providers reserve the right to monitor all staking-related activity for the purpose of fraud detection, regulatory compliance, and system integrity. Unusual or suspicious behavior may trigger automated or manual investigation protocols.

11.3. Prohibited Conduct: Users shall not:

1. Circumvent lock-up restrictions or attempt early withdrawal without entitlement;
2. Create duplicate or proxy accounts to manipulate reward eligibility;
3. Exploit smart contract or interface vulnerabilities for unauthorized gain;
4. Participate in any activity deemed unlawful, abusive, or inconsistent with staking program purposes.

11.4. Enforcement and Remedial Measures: In case of actual or suspected misuse, the Platform may:

1. Temporarily or permanently suspend access to staking services;
2. Withhold or reclaim rewards obtained through prohibited means;
3. Disable affected User accounts and initiate internal compliance actions;
4. Notify competent authorities, including law enforcement or financial regulators, where required.

11.5. Users acknowledge that the Staking Services are subject to rigorous internal and external compliance standards. Cooperation with any related investigation is a condition of continued participation.

Suspension and Termination of Services

12.1. Access to the Staking Services may be suspended or terminated without prior notice if:

2. The User fails to satisfy ongoing eligibility or verification criteria;
3. Regulatory instructions, court orders, or legal restrictions apply;
4. System security, user protection, or force majeure events require urgent action.

12.2. Suspension may result in temporary inaccessibility of Staked Assets, delayed rewards, and disabled platform features. In the event of termination, non-locked assets will be returned to the User’s Wallet subject to applicable verification and processing fees.

12.3. The Platform will notify affected Users via electronic means, except in cases where legal restrictions prevent prior disclosure. Termination shall not affect rights accrued before such date or obligations arising thereafter.

12.4. Locked Assets shall remain governed by the original terms of the Staking Program until the expiry of the Lock-Up Period, unless required otherwise by legal or regulatory intervention.

Limitation of Liability

13.1. To the maximum extent permitted by law, Capital, the Platform, its service providers, and affiliates disclaim liability for:

13.2. Users agree to indemnify and hold harmless the Platform, and affiliated personnel against any claim arising from violation of these Terms, applicable law, or misappropriation of services.

13.3. No Fiduciary Relationship: Participation in staking does not create an agency, trust, or fiduciary relationship. The Platform acts solely as a facilitator and does not manage user funds in a discretionary or advisory capacity.

Communications and Notifications

14.1. All staking-related communications shall be issued via the Platform interface and/or to the email address associated with the User’s verified account. It is the User’s responsibility to maintain accurate and up-to-date contact information.
