Frequently Asked Questions
Bitcoin is a decentralized digital currency that allows people to send and receive money over the internet without relying on banks or traditional financial institutions.
The Lightning Network is a fast and low-cost payment network built on top of Bitcoin. It allows for instant transactions with very low fees, making it ideal for micro-payments like cashback rewards.
Back4Sats is a Bitcoin cashback service. We partner with online stores to share a portion of their sales commission with you — in Bitcoin. It’s an easy way to earn sats while you shop.
There’s no catch. When you shop through Back4Sats, the store pays us a commission for referring you. We share most of that commission with you as Bitcoin cashback. It's a win-win!
Cashback payouts typically take around a month or a few months, depending on the store. This delay exists because merchants need to confirm that the purchase was not returned before approving the reward.
No account is needed! Just provide your BOLT12 invoice from your Lightning wallet before shopping, and we’ll automatically send your cashback once it’s ready.
You can optionally create an account using your Lightning Wallet, Google, or a traditional email and password. Either way, your cashback will be securely tracked and paid out.
Not yet. For now, withdrawals are only supported via the Lightning Network, but support for standard on-chain Bitcoin addresses is planned.
You can monitor your cashback status directly in your Back4Sats account dashboard.
Currently, cashback is only paid out to Lightning wallets. Support for other wallet types is planned for the future.
Tax regulations vary by country. In many places, cashback rewards are considered income. We recommend consulting a tax advisor familiar with cryptocurrency.
No. Cashback is paid only after the store confirms the purchase was not returned or refunded, ensuring the reward is valid.
No installation of our app is required! You just need to have a Lightning wallet installed—like Phoenix, BlueWallet, or any other Lightning-compatible wallet. Creating an account is optional for easier cashback tracking.
We partner with a growing list of online stores across various categories. Visit our website to see the current list of supported merchants.
Absolutely. We do not sell or share your personal data. Your information is stored securely and used only to process cashback rewards.
No, we do not see your personal data. Stores do not share that information with us. We only receive necessary details like purchase amount and commission to track and pay your cashback securely.
If your order is changed or canceled, cashback will not be awarded, as the purchase is no longer valid for rewards.
Most stores do not have a minimum purchase requirement, but some partners may set their own thresholds. Check the specific store details on our website.
Back4Sats works with many international stores, but availability depends on each merchant. Check the store list for details.
No, Back4Sats is completely free for shoppers. Stores pay us a commission for referring you, and we share most of it with you as cashback. The small remaining part helps us maintain and improve the service.
We convert the cashback amount from fiat to satoshi at the moment the cashback is registered by the store—not when it’s finally approved. Registration usually happens within about 2 days. At this point, we know exactly how many satoshi you will receive if the cashback is later confirmed, and this amount will not change.
