Chargebacks in crypto transactions can be a serious concern for merchants who offer fiat-to-crypto exchanges or wallet top-ups. Unlike traditional payments, crypto adds layers of complexity that make handling disputes more challenging — but also more manageable if you know how to prepare. In this article, we’ll walk through the key issues, best practices, and evidence you’ll need to safeguard your business and successfully defend against chargebacks.
What is a chargeback in crypto?
Chargebacks are essentially disputes initiated by cardholders through their bank, claiming they didn’t authorize or didn’t receive the service they paid for. In the context of crypto, this often involves transactions where fiat currency is exchanged for cryptocurrency, or where wallets are topped up.
The challenge with crypto is that transactions are irreversible on the blockchain. Once funds are sent, they can’t simply be “pulled back,” which means that traditional chargeback mechanisms clash with how cryptocurrencies fundamentally operate. This makes it critical for merchants to clearly document and prove every step of the transaction.

Two main scenarios: crypto purchases vs. wallet top-ups
In practice, crypto-related businesses typically deal with two transaction models.
- The first is a direct crypto purchase, where fiat is exchanged and crypto is immediately delivered to the wallet specified by the customer.
- The second is a wallet top-up, where funds are added to a digital wallet account, from which the customer may later purchase crypto or withdraw to another wallet.
In both cases, the key to protecting against chargebacks lies in properly defining what service was delivered. For a crypto purchase, the service is the delivery of crypto to the provided wallet. For a wallet top-up, the service is crediting the wallet balance.
The importance of robust Terms & Conditions
Your best defense starts long before any chargeback arises. Well-crafted Terms & Conditions (T&Cs) clearly explain what the transaction entails, your refund or cancellation policies, and the customer’s responsibilities. For instance, T&Cs should explicitly state that refunds are not possible if the fiat currency has already been converted to crypto or if the funds have been withdrawn.
It’s equally important to include disclaimers that the merchant is not liable for losses due to incorrect wallet addresses provided by the customer, or for any fluctuations in cryptocurrency value. Having the customer accept these terms — via a checkbox or, even better, a signed declaration — right before payment significantly strengthens your position in the event of a dispute.
What evidence do you need to defend a chargeback?
When a chargeback is filed, you’ll typically be asked to provide evidence such as screenshots of your T&Cs and proof that the customer accepted them. But depending on the transaction type, more documentation is essential. For direct crypto purchases, this means showing the transaction hash, the recipient wallet address, and a blockchain explorer screenshot confirming delivery.

For wallet top-ups, you should prepare evidence like wallet statements showing the credited amount and updated balance. If the funds were later used to buy crypto or were withdrawn, transaction history can further prove that the customer received the service they paid for.
Additional best practices: going beyond the basics
If your system captures device fingerprints, IP addresses, or even behavioral data tied to each transaction, these can be invaluable during a chargeback investigation. Showing that the same IP and device were used for the top-up, crypto purchase, and any withdrawal builds a strong case that the legitimate account holder completed the transactions.
It also helps to maintain a record of the customer’s transaction history with your platform. A pattern of successful transactions without prior disputes can help tilt the balance in your favor by demonstrating a longstanding, satisfactory relationship.
Chargeback Protection Checklist for Crypto Transactions
Navigating chargebacks in crypto isn’t just about reacting when a dispute arises — it’s about proactively building a system that minimizes risk from the start. Below you’ll find a practical checklist covering the most important safeguards discussed in this guide. Use it to audit your current processes and close any gaps before they turn into costly chargebacks.
- Clearly structured Terms & Conditions
Make sure your T&Cs explicitly state what service you provide (crypto purchase vs. wallet top-up), include a detailed refund and cancellation policy, and disclaim liability for incorrect wallet addresses or currency fluctuations.
- Customer acceptance before payment
Require customers to actively accept your T&Cs and refund policy — ideally with a checkbox such as:

“I have read and accept the Terms and Conditions and the Cancellation Policy (Refund Policy).”
- Maintain strong evidence for each transaction
- For direct crypto purchases: store the transaction hash, recipient wallet address, and a blockchain explorer screenshot confirming delivery.
- For wallet top-ups: keep wallet statements showing the credited balance and any subsequent crypto purchases or withdrawals.
- Collect device & network data
Capture device fingerprints, IP addresses, and timestamps to tie user actions (top-up, crypto purchase, withdrawal) to the same session or environment.
- Follow Visa’s best practices
- For custodial services: keep records proving the account balance was updated, along with device/IP data.
- For self-custodial on-ramps: store on-chain evidence showing funds were delivered to the wallet address provided by the customer.
- Keep a history of successful transactions
A track record of prior transactions without disputes can strengthen your position if a chargeback does occur.
Chargebacks in crypto payments don’t have to be a barrier to growth. By setting clear expectations through solid Terms & Conditions, collecting robust evidence for each transaction, and using advanced tools like device tracking, you put your business in the strongest position to defend against disputes.
