Introduction

recv is a non-custodial crypto payment gateway. Customers pay you on-chain, the funds land directly in your own wallet, and recv never touches the money. Instead of taking a percentage of every transaction, recv charges a flat subscription — there are no turnover fees.

What recv does

• Creates invoices. You generate a payment request for a USD amount on a specific blockchain network. recv converts the USD price into the payable on-chain amount, picks one of your payout wallets as the destination address, and returns a hosted checkout link plus a payment URI.
• Watches the chain. recv's watchers observe incoming transfers to your destination addresses and match them to open invoices.
• Confirms and notifies. When a matching transfer is seen, the invoice transitions (paid, underpaid, overpaid, manual_review), and recv fires a signed webhook to your endpoint.

Non-custodial model

You connect payout wallets per network in the Merchant Console. Every invoice is created against one of your addresses, so settlement is direct customer → merchant. recv's role is detection, accounting, and notification — not custody. There is no payout step, no recv-held balance, and no withdrawal flow.

Supported networks

recv settles payments on GRAM on TON, USDT on TON, TRON, Base, and BSC. See Supported Networks for the exact list and per-network notes.

Two ways to integrate

1. REST API (/v1). API-key-authenticated endpoints for creating and managing invoices, plus signed webhooks for status changes. Start with the Quickstart.
2. MCP server (AI agents). A Model Context Protocol server that lets AI agents (Claude Desktop, Cursor, etc.) create and check invoices, verify webhooks, and list networks as tools. See MCP / AI Agents.

Getting started

Create an account in the Merchant Console, add a payout wallet, then issue an API key from the Developer Portal. The Quickstart walks through it end to end with curl.
