NNCash — Terms of Service

Effective date: June 10, 2026 Last updated: June 10, 2026

These Terms of Service ("Terms") are a binding agreement between you ("you", "User") and NNCash Pte. Ltd. ("NNCash", "we", "us") governing your use of the NNCash mobile application (the "App"), the nncash.xyz website, and related services (collectively, the "Services").

By creating an NNCash account or using the Services, you accept these Terms and our Privacy Policy. If you do not agree, do not use the Services.

1. Definitions

2. Eligibility

To use the Services you must:

• Be at least 18 years old (or the age of majority in your jurisdiction, whichever is higher)
• Have the legal capacity to enter into a binding contract
• Not be a resident of, or located in, a jurisdiction where the Services are prohibited or where we do not offer them (currently we do not offer Services in jurisdictions subject to comprehensive sanctions, including those listed by the United Nations, EU, OFAC, or HMT)
• Not be on any sanctions or denied-parties list

We may refuse to open or maintain an Account for any User at our sole discretion, including for reasons of regulatory compliance, fraud prevention, or risk management.

3. Account creation

When you create an Account, you must provide accurate, current, and complete information. You are responsible for:

• Keeping your contact details up to date
• Maintaining the confidentiality of your login credentials (phone, email, OAuth tokens, biometric authentication)
• All activity that occurs under your Account, whether or not authorised by you

Notify us immediately at support@nncash.xyz if you suspect unauthorised access. You can also freeze your Wallet from inside the App (Wallet → Freeze) to immediately halt outgoing transactions.

We may suspend or close your Account if information you provided is materially false, incomplete, or out of date.

4. Identity verification (KYC) and account tiers

Use of the Services is subject to identity verification and tiered limits. Your tier determines your maximum balance and transaction limits.

Verification is performed by our partner Did.it. We may require additional information at any time to comply with KYC, AML, or sanctions obligations.

If you do not complete verification when required, we may:

• Restrict your ability to transact
• Freeze your Wallet
• Close your Account

KYC outcomes (approved / declined / pending) are recorded on your Account but the underlying identity documents are held by Did.it under its own privacy policy.

5. Wallet services

5.1 Custodial wallet model

When you create your NNCash Wallet, we provision an NNChain chain wallet on your behalf. The cryptographic keys for that wallet are held in the NNChain signing service which we operate. You do not currently hold the private keys yourself — this is a custodial model.

We maintain strict controls on key material:

• Access is restricted to senior operations staff with SUPER_OPS role
• Every privileged access is audit-logged
• An additional second factor is required at the custody backend before any key material can be released

We may offer a self-custody option in future releases.

5.2 Wallet address and on-chain transparency

Your Wallet has a unique chain address of the form nnc1…. This address is:

• Public — anyone you share it with (or anyone who scans your receive QR) can view it
• Pseudonymous — the address is not directly linked to your identity in the public ledger, but the link exists in our internal records
• Permanent — on-chain transactions are recorded permanently on NNChain and cannot be removed or reversed

You can verify your transactions on NNScan.org or via NNChain RPC endpoints.

5.3 Wallet freeze and unfreeze

You can freeze your Wallet at any time from the App (Wallet → Freeze). When frozen:

• Outgoing transactions are blocked
• Incoming deposits still arrive but cannot be withdrawn until you unfreeze

You can unfreeze at any time from the App, provided the freeze was your own action. If the freeze was applied by NNCash (e.g. for compliance or security reasons), you must contact support@nncash.xyz to discuss.

5.4 NNCash's right to suspend or freeze your Account

We may freeze your Wallet, suspend your Account, or refuse to process a transaction if we believe, in good faith, that:

• The Account is being used for prohibited activities (see §10)
• There is a risk of fraud, money laundering, sanctions violation, or other illegal activity
• We are legally required to do so (court order, regulatory request, sanctions designation)
• Your behaviour poses a risk to other Users or to the integrity of the Services
• You are in material breach of these Terms

When we freeze or suspend, we will notify you unless legally prohibited from doing so.

6. Transfers and payments

6.1 Sending funds

You can send funds to other NNCash Users by phone number, email, @handle, or QR code. Internal NNCash-to-NNCash transfers are processed instantly and recorded only in our private ledger.

Cross-chain deposits and withdrawals (entering or leaving NNCash) are settled on the NNChain network and may take several seconds to several minutes to confirm.

6.2 Receiving funds

You can receive funds by sharing your phone, email, @handle, chain address, or receive QR.

6.3 Limits

Transfer limits are determined by:

• Your KYC tier (see §4)
• Daily and monthly velocity limits
• Per-transaction limits
• Country-specific or asset-specific restrictions where applicable

We display applicable limits in the App.

6.4 Fees

Fees vary by Asset, transaction size, country, and channel. The fee for each transaction is displayed in the App before you confirm. By confirming, you authorise us to deduct the displayed fee.

Current fee schedule: see # or the in-app quote.

6.5 Irreversibility

Transactions on NNCash, once confirmed, are generally irreversible. We do not offer chargebacks. If you send to the wrong recipient, your recovery depends on the recipient's willingness to return the funds.

Always double-check the recipient before confirming.

6.6 Cross-chain withdrawals

On-chain withdrawals to external NNChain addresses cannot be reversed by NNCash once broadcast. NNCash is not responsible for funds sent to an invalid or unsupported destination address.

7. Swap services

The App offers swaps between supported Assets at the prevailing market rate provided by our liquidity partner.

• Quoted rate is indicative and may change between quote and execution
• Slippage tolerance is configurable; if execution price exceeds the tolerance, the swap is cancelled
• Network fees for cross-chain swaps are passed through to you
• We do not guarantee that any swap will succeed or that liquidity will be available

Swaps may be subject to additional KYC checks for amounts above certain thresholds.

8. Deposits and withdrawals (fiat / bank)

If you fund your Wallet via bank transfer or other fiat method:

• Settlement times depend on your bank, payment rail, and country (typically 1-3 business days)
• We may impose holds on incoming deposits for fraud or compliance reasons
• Fees are disclosed before you initiate the deposit
• Withdrawals to your bank are subject to identity verification, sanctions screening, and applicable limits

Bank deposits/withdrawals are facilitated through licensed payment partners and are subject to those partners' terms.

9. NNTerminal merchant services (Phase 2 — where applicable)

If you operate as a merchant using the NNTerminal device or merchant portal:

• Additional terms apply (see merchant agreement)
• You agree to provide accurate business information
• You are responsible for compliance with consumer-protection, tax, and refund laws in your jurisdiction
• We may require additional KYC documents for the business entity

10. Prohibited use

You agree NOT to use the Services for, or in connection with, any of the following:

• Money laundering, terrorism financing, or proliferation financing
• Sanctions violations or transactions involving sanctioned persons, entities, or jurisdictions
• Fraud, identity theft, or impersonation
• Illegal gambling
• Sale of illegal goods or services (including controlled substances, weapons, or stolen property)

• Using automated means (bots, scrapers) without our written permission
• Reselling, sublicensing, or otherwise commercially exploiting the Services without authorisation
• Misrepresenting your identity, location, or intentions

If we determine you have engaged in any prohibited use, we may immediately:

• Freeze your Wallet
• Suspend or terminate your Account
• Reverse pending transactions
• Withhold funds for as long as required by law
• Report to law enforcement or regulators

11. Anti-money laundering (AML) and sanctions

NNCash complies with all applicable AML, counter-terrorism financing, and sanctions laws in jurisdictions where we operate. You agree:

• Funds you deposit are from lawful sources
• You will provide additional information about the source of funds upon request
• You consent to sanctions screening of yourself and your counterparties
• We may report suspicious activity to applicable financial intelligence units

We use automated monitoring + manual review to detect unusual patterns. Detection or suspicion of money laundering or sanctions evasion will result in Account suspension, fund freezing, and reporting to authorities.

12. Disclaimers and risk warnings

12.1 Not financial advice

NNCash does not provide investment, tax, legal, or financial advice. Information shown in the App (such as swap rates, balances, or chain statuses) is for informational purposes only.

12.2 Crypto / token risks

Holding and transacting Assets — particularly NNC and stablecoin-pegged assets like NUSD — carries financial risks:

• Volatility: prices can fluctuate rapidly
• Liquidity: certain Assets may have limited or no liquidity at times
• Technology: bugs, exploits, or chain forks may affect Asset availability
• Counterparty: stablecoins depend on the solvency and policies of their issuers
• Custody: the NNChain custody backend is operated by us; an incident there could affect Wallet availability

You acknowledge these risks and agree to use the Services at your own risk.

12.3 "AS IS" basis

To the maximum extent permitted by law, the Services are provided "as is" and "as available" without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, accuracy, or uninterrupted availability.

• Our total cumulative liability for any claim arising from or related to the Services shall not exceed the greater of (a) the total fees you paid to NNCash in the 12 months preceding the claim or (b) USD 100
• This limitation applies whether the claim is based on contract, tort, statute, or any other legal theory

Some jurisdictions do not allow the exclusion of certain warranties or limitation of liability for consequential or incidental damages; in such jurisdictions, our liability is limited to the greatest extent permitted by law.
