We build payment rails.

Crypto payment gateway development is the engineering of systems that let merchants and users send, receive or settle value using cryptocurrencies — typically stablecoins — while handling the reconciliation and operational needs of a real payment product. Full builds include payment-intent infrastructure, settlement on the right chain and stablecoin, on/off-ramp integration, identity onboarding and transaction monitoring, reconciliation across blockchain and banking ledgers, dispute workflows and treasury automation.

Cost is driven mostly by geographic coverage, product surface complexity, banking-partner integration count and dispute-resolution framework — not by the crypto-transfer mechanics, which are usually the smallest piece. A crypto-only merchant checkout in one country is lighter than a cross-border remittance app serving eight corridors, which is lighter than a global rail with card issuing. Integration count is the number that moves the estimate most.

It depends on the corridor and on what your counterparties will actually accept. USDC tends to be the institutional default. USDT has the largest network effect, especially in Asia and Latin America. PYUSD suits PayPal-ecosystem products; EURC fits EUR-denominated flows. Regional stablecoins fit local treasury needs. Most serious products support several and route by user geography, because a single choice locks you out of corridors you will eventually want.

Checkout surfaces, a payment-intent service with idempotency and retry logic, settlement on appropriate chains and stablecoins, on/off-ramp integrations with multiple providers per geography, an onboarding and monitoring pipeline, a reconciliation engine with accounting sync, dispute-resolution workflow, treasury automation and operator monitoring. Licensing and banking-partner commercial relationships stay entirely with you and your counsel. We build the software and integrate the APIs.

For almost all teams, integrate providers. Building your own ramp is a multi-year undertaking with real capital behind it, and it is very rarely the constraint actually holding a product back. Integrating several providers per geography covers reliability and coverage gaps for a fraction of the effort. Building your own only starts to make sense once you already hold the banking relationships, coverage gaps are genuinely blocking growth, and the volume justifies running it as its own operation.

You and your counsel do. We are engineers, not advisers, and we do not take that on. What we do is build to the requirements they hand us. In practice that means your team tells us the onboarding depth, the monitoring and the reporting the product has to support, and we architect those into the data model directly rather than bolting a vendor on at the end. The difference matters: a system designed to keep a decision record can produce one later. A system that was not, cannot.

Merchant gateways serve businesses accepting payment for goods or services; remittance platforms serve individuals sending value across borders. Merchant gateways face chargeback and dispute workflows and accounting integrations. Remittance platforms face destination-country cash-out operations and consumer-facing screening, corridor by corridor. The engineering overlaps at the stablecoin-settlement core and diverges on the product surface.

Custom earns its place once your volume, geography or product surface outgrows what packaged providers will do. Multi-corridor settlement, unusual reconciliation, per-market routing and deep accounting integration are the usual triggers. Below that, a packaged provider gets you taking payments sooner and inherits fraud and banking infrastructure you would otherwise build. Plenty of our payment work sits on top of providers rather than replacing them, giving you the custom behaviour where it matters. We scope against your real volumes and corridors.
