KuvarPay: accept crypto on any chain, settle in local currency

A payment gateway that takes Bitcoin, Solana, Stellar and EVM payments, converts across five collection currencies, and settles the business in the currency it actually banks in.

The challenge

A business that decides to accept crypto inherits every hard part of it at once: which chains to support, which coins, how to price against a rate that moves while the customer is still on the checkout page, and how to end up holding money it can actually pay salaries with.

Doing that properly means running node infrastructure, an internal ledger, FX, and compliance in four different places. Most merchants are not equipped to run any of it, and the ones who try end up holding assets they never wanted.

What we did

We built one gateway across four chain families — Bitcoin, Solana, Stellar and EVM — so the merchant integrates once and never learns the differences between them. Customers pay in whatever they hold.

Collection is supported in five global currencies, with FX handled server-side and settlement amounts derived from the session rather than recalculated on the client, which is where rounding and timing errors normally creep in. The business is paid out in its own currency.

Around that sits the rest of a real payments product: hosted checkout, payment links, POS, an API with a sandbox simulator, split payments, subaccounts, and on-chain recurring billing through an upgradeable subscription contract. Settlement and webhook delivery run as queued background jobs so a slow chain never blocks a checkout, and the merchant dashboard streams status over server-sent events.

Identity checks run in-house, including on-device liveness detection, rather than being outsourced to a third party that would not cover every market we operate in.
