# Welcome to InfraIO Pay **InfraIO Pay** is a crypto checkout platform for merchants. You add our JavaScript SDK, send customers to a hosted checkout, and the on-chain payment settles to your wallet. Stablecoin-first (USDT, USDC), non-custodial, with webhook-driven order confirmation. These docs are organized by what you want to do. ## Start here - [Quickstart](https://docs.infraio.xyz/en/get-started/quickstart) — Take your first test payment in about 10 minutes: load the SDK, open a checkout session, and receive the webhook. - [Concepts](https://docs.infraio.xyz/en/concepts/sessions) — How sessions, orders, payment intents, and webhooks fit together. - [API reference](https://docs.infraio.xyz/en/api-reference/authentication) — Endpoint-by-endpoint specs, request/response schemas, and error codes. - [SDK reference](https://docs.infraio.xyz/en/sdks/javascript) — `@lartech/infraio-checkout-js` — install, init, checkout modes (popup, redirect, embed), event callbacks. ## What InfraIO Pay is not - **Not a custodian.** Funds move on-chain from the buyer to your treasury wallet directly. We never hold your balance. - **Not a wallet requirement.** Customers pay from their own wallet (or use the per-order deposit address); you connect an existing wallet address when you sign up. [InfraIO Wallet](https://docs.infraio.xyz/en/wallet/overview) is a separate non-custodial passkey wallet. Per-order deposit addresses are EVM-only; on TRON, Solana and TON the buyer pays your wallet directly (see [Direct-to-wallet networks](https://docs.infraio.xyz/en/concepts/chains#direct-to-wallet-networks)). - **Not a fiat ramp.** Buyers aren't asked for identity verification; you receive what they paid, in the asset they paid in. If those constraints don't match your use case, [talk to sales](https://infraio.xyz/sales) about hybrid setups. ## Contact / support Email [contact@lartech.xyz](mailto:contact@lartech.xyz).
