Sound familiar?

International clients are ready to pay, but their cards don't go through — orders die at checkout

Card processing for your niche is expensive or unavailable: high-risk rates eat the margin

Chargebacks: a payment reversed a month later, the goods unrecoverable, the dispute lost

Ready-made crypto processors take heavy fees and hold your funds on their side

Who crypto payments solve a real problem for

Crypto payments on a site aren’t a fashion tribute but an answer to three concrete pains. An international audience: clients from countries whose cards don’t pass your acquiring — lost revenue that USDT returns in one payment. High-risk niches: where bank acquiring is expensive or unavailable, a network fee of fractions of a percent changes the economics. And chargebacks. For digital goods and services, a payment recalled a month later is an uncompensated loss. A confirmed blockchain transaction is final.

A checkout that doesn’t scare the client

The crypto-is-complicated fear is cured by the right flow. The client sees a familiar invoice: the sum, the address, a QR code, a rate-lock timer. They pay from any wallet — the site itself waits for the network confirmations and switches the order status via a webhook. No send-a-transaction-screenshot and manual reconciliation. For the client it’s no harder than paying by card. For you it’s a fully automatic process.

Edge case engineering — what separates working acceptance

Crypto payments’ real complexity isn’t in the acceptance but at the edges. The client sent 2% less: the wallet’s fee. Paid twice. The payment arrived after the timer expired. The network is congested. We design scenarios for each case. A top-up in one link. Automatic crediting or refund of the overpayment. A late-payment policy. Without this, accepting crypto turns into a queue of stuck orders in support. With it, it runs like clockwork.

Volatility and custody: the rate isn’t your problem

Accepting BTC doesn’t mean holding the rate risk. Auto-conversion swaps volatile coins into stablecoins right after confirmation. The rate is locked at the payment’s moment, the till holds predictable USDT. The scheme is non-custodial. Funds arrive at your wallets, no middleman holds your money or can freeze it. A panel with per-wallet reconciliation and exports gives accounting a working tool, not a blockchain explorer printout.

The launch and the frame

The integration takes 3-6 weeks. Connecting to your site and books, configuring the coins and confirmations, edge case tests on a testnet, launch with monitoring. An important honesty: the legal scheme — the jurisdiction, the paperwork, the accounting — you build with your lawyers. Regulation differs by country and changes. Our zone is a flawless technical implementation of the scheme you chose. From smart contracts to reports compatible with your books.

Client reviews

Client reviews

Half the audience is countries whose cards don't pass. Crypto payments opened those markets within a month. The client pays USDT, the subscription activates automatically. Revenue grew by a third simply because the money could arrive.
Demid S.SaaS founder
Chargebacks were our main pain. A digital product can't be returned, and we lost the disputes with the processor. With crypto that class of problems vanished completely: a confirmed payment is final.
Lev T.Digital goods store owner
We principally wanted a non-custodial scheme after the stories of frozen funds at processors. Here the money arrives straight to our wallets, the stablecoin conversion is automatic. There are no middlemen in the chain.

FAQ

FAQ about crypto payments

01How much does crypto payment integration cost?

Integrating acceptance into the site from $5,500, launched in 3-6 weeks. The price depends on the coin and network list, the conversion scheme and the depth of the link with your accounting. The quote follows a free task review.

02Is it legal? How do we account for such payments?

Regulation depends on your business's jurisdiction and changes. Here we're the technical side, not the legal one. The working scheme — the entity, the jurisdiction, the accounting — you define with your lawyers. We implement it technically and provide transparent reports for the books.

03Which coins and networks do you support?

The base is USDT on TRC-20 and ERC-20, the most common payment routes, plus BTC and ETH. We add coins and networks for your audience. For each we configure the confirmation count: the balance of speed and reliability.

04How do we protect against rate volatility?

Two mechanisms. The rate timer in the invoice: the sum is fixed for the 15-30 minutes of payment. And auto-conversion of volatile coins into stablecoins right after confirmation. You accept BTC — you hold USDT. The rate risk shrinks to minutes.

05What about refunds if there are no chargebacks?

Refunds remain your business decision, not one imposed by a bank. The panel lets you send a refund to the payer's wallet in a couple of clicks. The difference is that you make the call. A payment can't be recalled behind your back a month later.
