How blockchain can lower payment processing fees

Where traditional card-processing fees come from

A card payment connects several participants: your customer's issuing bank, the card network, your acquiring bank, and the payment services your business uses. Your merchant rate pays for that arrangement. Depending on your contract, the costs appear as one bundled price or as separate charges on your statement.

Visa describes interchange as a fee between acquiring and issuing banks. Merchants pay their financial institution a negotiated merchant discount, which can include several services. That distinction matters when comparing prices: a headline processing rate does not always tell you what the whole transaction costs.

A different payment rail removes some layers of cost

When a customer pays directly from a supported crypto wallet, the transfer runs on a blockchain instead of through a card network. There is no card issuer charging interchange for that blockchain transfer and no card-network assessment on it. A payment platform can still charge for checkout, payment detection, conversion, and the other services it provides.

This is the practical reason blockchain can reduce fees. It changes the infrastructure used to move the payment. The benefit can be especially useful when customers already hold a supported stablecoin, because they can pay without first buying it through a separate service.

Network choice also matters. Base's documentation explains that its transaction costs include execution and Ethereum security components, and that fees vary with network activity. A low-cost network can help, but a blockchain fee should never be described as permanently fixed or zero.

Which fees still apply?

Compare the cost from the customer's starting currency to the money your business can use. A small network fee alone is not the price of a complete merchant payment service. Depending on the route, your calculation may need all of the following:

• The payment platform's processing fee, including any account-specific rate or agreed markup.
• Blockchain network fees for the relevant transfers.
• Conversion fees or exchange-rate differences when the source asset and settlement asset differ.
• Payout or bank-transfer fees when moving proceeds to your destination.
• Applicable verification or other service charges, plus your team's reconciliation work.

A practical Ulasend pricing example

Ulasend publishes processing rates starting at 0.5%. New accounts automatically start at a standard 1% platform rate; existing agreed rates remain in effect, and approved referral markups may apply. Check your account's rate and the fee schedule before making a cost comparison. Network, conversion, bank-transfer, and other applicable service fees are separate.

For illustration, a 1% processing fee on a $1,000 payment is $10. If your existing provider's comparable processing charge is $30, the processing-only difference is $20. This is arithmetic using hypothetical comparison inputs, not a quote or a promise of $20 in net savings. Add each route's other costs before deciding which is cheaper.

Merchants can pay Ulasend's processing fee from their proceeds or pass it to customers as a separate checkout line. Passing a fee changes who pays it; it does not remove that cost from the transaction.

Buying crypto with a card is a separate cost

If a customer first buys crypto with a credit or debit card, that purchase still uses card rails. The purchase provider may charge card-processing, conversion, and network fees. Receiving crypto at the end does not make the earlier card purchase free.

For a useful comparison, ask whether your customers already hold the supported asset and network. Then review the full quote and the amount the business receives. An attractive merchant fee can be less attractive to a customer who must pay additional costs to obtain the payment asset.

Compare real payments before changing your checkout

Start with a typical order value and your current monthly statement. Compare the same volume, currency, customer location, and payout destination. Include refunds and the time spent reconciling payments in your operating budget, rather than treating every sale as an ideal transaction.

Offer a supported stablecoin route where it makes sense for your customers, then measure completed payments and total costs. Ulasend's fee schedule and supported-assets guide are the best starting points for checking the available setup.
