2026-07-21 — Initial release

InfraIO Pay is live. Crypto checkout for merchants — stablecoin-first (USDT / USDC), non-custodial, with on-chain settlement straight to your merchant wallet and webhook-driven order confirmation.

What ships in this release:

  • JavaScript SDK — @lartech/infraio-checkout-js. Drop in the SDK and open a hosted checkout in popup, redirect, or embed mode. See the SDK reference.
  • REST API — an HMAC-SHA256-signed B2B surface for your backend plus a dashboard (JWT) surface, under https://api.infraio.xyz (https://api-dev.infraio.xyz for test). See the API reference.
  • Hosted checkout — buyers pay from their own wallet or a generated deposit address; the page settles the on-chain transfer and returns control via onSuccess / onCancel (or your success_url / cancel_url).
  • Webhooks — HMAC-signed over timestamp + "." + body, with a documented event catalog, automatic retries, and per-delivery replay. See Webhooks.
  • Refunds — merchant-initiated refunds plus a customer-facing refund-request flow: mint a token, point the buyer at a hosted form, and settle to a destination they choose. See Refunds.
  • Multi-chain, stablecoin settlement — pay across supported EVM networks; test mode runs on real public testnets. See Chains & assets.
  • Localised checkout — the checkout and refund pages render in 10 languages, following the locale you pass to the SDK.

Start with the Quickstart.
