Build recurring stablecoin payments

Virio is wallet-native recurring payments and programmable billing infrastructure for stablecoins. Everything is onchain, public, and permissionless — integrate with your own RPC and the @virio/sdk framework. No API keys, no accounts, no hosted services.

Getting started

Introduction

What Virio is, why recurring stablecoin payments matter, and how the protocol fits together.

Quickstart

Accept recurring stablecoin subscriptions on testnet in under ten minutes.

Build

Core Concepts

The mental model behind Virio — plans, subscriptions, permissions, execution windows, executors, fees, and settlement.

SDK Reference

Every method, option, and type in the @virio/sdk TypeScript client.

Drop-in Button

Add crypto subscriptions with one component — native React, Vue, and Angular entrypoints, plus a Web Component for plain HTML. WalletConnect, plan lookup, approvals and signing handled for you.

Webhooks & Events

React to settlement in real time — onchain events plus optional self-hosted signed webhooks.

Protocol

Smart Contracts

The onchain surface — VirioSubscriptionManager, VirioPayrollManager, and the EIP-7702 delegate.

Security

Threat model, protocol guarantees, and integration checklists for merchants, frontends, and executors.

Permissionless Subscriptions

How Virio handles recurring ERC-20 payments without custody, hosted accounts, or a privileged billing server.
