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

Take your first test payment in about 10 minutes: load the SDK, open a checkout session, and receive the webhook.

Quickstart

How sessions, orders, payment intents, and webhooks fit together.

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 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).
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 about hybrid setups.
