Terms of Service

Last update: 2024-08-23

  1. Acceptance of Terms. By downloading and using the Yopaki mobile application ("the App") provided by Aztec Solutions, Inc. ("Yopaki"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree with these Terms, you should not use the App.

  2. Privacy: By accepting these terms, you are also accepting the use of your data as described in our Privacy Policy.

  3. Services and Game Rules. The App provides an online card gaming platform. The App offers a mobile version of the game Loteria. Games last for 1 week and then reset. Users do not have to pay or purchase anything to play but may win Bitcoin as a reward. Rewards are not guaranteed. The rewards will not be paid out in the initial months until the Bitcoin withdrawal functionality is implemented. By using the App, you agree to abide by the game rules and guidelines established by Yopaki.

  4. Eligibility and Verification. Rewards may only be payable to users who can verify their email and phone number. Yopaki reserves the right to verify a user's identity through ID verification and a video call if the reward is over USD 100. The App is intended for users who are at least 13 years of age. By using the App, you confirm that you are at least 13 years old.

  5. Compliance and Restrictions. The App complies with OFAC international regulations. Users from OFAC-sanctioned countries are not permitted to register, play, or participate in any activities offered by the App. Yopaki reserves the right to terminate accounts and void any associated rewards of users found to be in violation of this clause. It is the responsibility of each user to ensure they are not subject to OFAC sanctions prior to using the App.

  6. Referral Rewards. As part of our ongoing efforts to enhance your experience with the App, we offer a referral program that allows you to earn additional rewards. For each new user you refer to the App who successfully registers and participates, both you and the referred party will receive a bonus of 500 satoshis ("SATS"). Please note that the terms of this referral program, including the reward amount, are subject to change at any time without prior notice. We encourage you to stay updated with the latest terms to maximize your benefits from this program.

  7. Minimum Payout Threshold. To ensure a streamlined and efficient payout process, we have instituted a minimum threshold for rewards payouts and withdrawals. Users must accumulate at least 21,000 SATS, either through gameplay winnings or referral bonuses, before they can initiate a withdrawal of their rewards. This policy is in place to optimize transaction costs and enhance the overall user experience on our platform. Please ensure that your accumulated rewards meet or exceed this threshold before requesting a payout.

  8. Wallet. The Yopaki application enables you to create a non-custodial cryptocurrency wallet for Bitcoin, and to use the Wallet to store, send, request, and receive Bitcoins. Our application is intended for use by persons who are very knowledgeable about cryptocurrency generally and non-custodial wallets in particular. If you use our service, you represent that you qualify as such a person.

    a. Responsibility for the wallet's seed. The application uses a 12-word phrase ("Seed", "Mnemonics") as a seed to a Lightning wallet and a BIP32 hierarchical wallet. This seed gives access to all assets stored in the wallet. If you use Yopaki to create a Wallet, the wallet will use an algorithm to generate a seed. This seed is stored on your device only. We do not know, store, or have access to your seed. We cannot provide assistance if you lose or forget your seed. It is your responsibility to carefully guard your seed and make a backup. You must not give the seed to anyone. Seed and impact of their loss or misappropriation If you permanently forget or lose your seed, you will never be able to recover any funds in your wallet and will suffer a complete, irrecoverable, and catastrophic loss of all funds in your wallet. Yopaki has no responsibility and will not be liable for any loss or damage you suffer from the loss or misappropriation of your seed.

    b. Securing access to the application. If available on your device, Yopaki provides a way to prevent unwanted access to your wallet, using the device's biometrics system. It is your responsibility to make sure your device's biometrics authentication system is properly configured and only grants access to you. Keeping your device up-to-date and secure You must make sure the device the application is running on is secure, especially that its Operating System is up-to-date, with the latest security patches available. Your device must not be rooted; otherwise, the application will not be secure, and your seed will be exposed.

    c. How it works. Yopaki in-app wallet is a non-custodial, Bitcoin-only wallet that uses the Lightning Network to store, receive, and send payments over Lightning. You need to have a working Internet connection to use the wallet. The application connects to a Lightning node ("Peer") managed by Yopaki, and in cooperation with the peer will automatically open, maintain, and close Lightning payment channels. Those channels are secured using multisig transactions signed with your seed and the peer's. The wallet's balance is the aggregate usable balance of your payment channels. Payments are relayed by the peer through your channels. If you cannot connect to the peer, you will not be able to send or receive payments. As much as possible, the wallet and the peer will cooperate in order to make payments complete properly, either with a failure or a success. However, in some cases, including but not limited to payment errors or connection issues, a payment may not be able to complete properly, in which case the channels that forwarded the faulty payment will have to be force-closed (see the Termination section).

    d. Outgoing Lightning payments. The wallet delegates route calculation to the peer and provides the peer with a range of acceptable fees that the peer can use at discretion.

    e. Incoming Lightning payments. The peer will try to use existing payment channels when possible. If none are able to accept the payment, the payment will fail.

    f. Outgoing Lightning payments. The wallet delegates route calculation to the peer. When sending payments, the wallet allocates a fixed fee to the peer to route the payment. If no route can be found, the payment fails and funds come back to the wallet.

    g. Incoming Lightning payments with enough liquidity. When a payment is incoming to the wallet, and the wallet has enough inbound liquidity, the payment is received without incurring any fees.

    h. Incoming Lightning payments with no channel, or insufficient liquidity When a payment is incoming to the wallet, and the wallet has no channel, the peer will open a new channel. When a payment is incoming to the wallet, and the wallet already has a channel but insufficient liquidity, the peer will automatically splice the funds into that existing channel. In both cases, channel creation or splice-in, the operation involves an on-chain transaction whose fees are paid by the wallet. In addition, a fee is paid to the peer for the operation. The wallet may reject the splice-in or the channel creation at discretion, for example, if the fee is too high. In that case, the payment fails. This is done automatically, using user-configurable settings in the wallet.

    i. Payments to on-chain addresses ("swap-out"). The wallet is able to splice funds out of their channels and send these funds to an on-chain Bitcoin address. The wallet may use a feerate of its choosing for this operation. This operation decreases the capacity of the channels involved in the splice.

    j. On-chain transactions to the wallet ("swap-in"). The wallet can receive funds on an on-chain multisig address managed by both the peer and the wallet. After confirmations, funds on that wallet will be swapped to Lightning channels. The swap involves an on-chain transaction whose fees are paid by the wallet. Only after the swap will the wallet be able to spend these funds. The wallet may reject swap-in attempts, including if the fee is too high. This is done automatically, using user-configurable settings in the wallet. In that case, funds remain on the swap-in wallet as unspent outputs. Unspent outputs on the swap-in wallet will be able to be swapped as long as they are within the delay of the multisig scheme. Once that delay has passed, unspent outputs will not be eligible for swap. Instead, the user will be able to spend these funds on-chain.

    k. Requesting liquidity. The user is able to manually request inbound liquidity from the peer, against a fee that is paid to the peer. The peer provides this liquidity for a given duration. During that duration, the peer will not voluntarily close or splice the requested amount of liquidity out of the channel. After that duration has expired, any requested liquidity that has not been used can be spliced out by the peer.

    l. Fee credit. On some platforms, the wallet is able to use a fee credit system, managed by the peer, and used to prepay the fees for incoming Lightning payments. This allows the user to accept an incoming payment even if that payment is too small to cover the incoming fees by itself. When that happens, some or all of the incoming amount accrues to the user's fee credit. This fee credit will be consumed when a channel is spliced or force-closed, or when another incoming payment arrives that cannot pay its own fees. The terms and amount of the fee credit system may vary from peer to peer, and Yopaki reserves the right to stop offering fee credits at any time.

  9. Platform Compliance. The App complies with all guidelines and policies of the Apple App Store and Google Play Store.

  10. Account Misuse. Yopaki reserves the right to suspend or terminate your account if it suspects any misuse or fraudulent activity.

  11. Amendments. Yopaki reserves the right to amend these Terms at any time. You will be notified of any changes, and continued use of the App will signify your acceptance of these changes.

  12. Ambassador Program. The Yopaki Ambassador Program is designed to reward the most dedicated and influential users. Once a user reaches the milestone of successfully referring 100 people to the App, not only will the user unlock a reward of 20,000 sats, but will also be granted the status of a Yopaki Ambassador. As an Ambassador, the user unlocks the exclusive benefit of earning 21% back from any fees incurred by any of the users referred, which will be applicable to current and future transactions within the App (including but not limited to buy, sell, and other transactional features). Please note that the Ambassador Program is subject to specific terms and conditions, which will be provided upon achieving Ambassador status.
