Connext Browser SDK

The Connext Browser SDK is the simplest way to add micropayments to any web app.

Connext is the protocol for p2p micropayments, built using state channels on the Ethereum blockchain. This SDK creates a Connext client inside of an iframe in your browser page, and then uses that client along with some minimal UI components to dispatch transfers to a recipient.

The SDK supports the following features:

• 🎩 Email-based login via Magic.
• 💳 Debit card on/offboarding via Moonpay.
• ⛽ End-to-end Ethereum gas (transaction fee) abstraction.
• 💵 Transfers in USD by default, with optional customizeability to other currencies.
• 🦊 Login using any popular Ethereum wallet such as Metamask. (coming soon!)

Installation

You can install the SDK using npm:

npm i --save connext

Usage

After installing, import the SDK into your web app, instantiate it and open the login UI.

import ConnextSDK from "connext";

const connext = new ConnextSDK();

// login
await connext.login();

// publicIdentifier
const publicIdentifier = connext.publicIdentifier;

// balance
const balance = await connext.balance();

// deposit
await connext.deposit();

// transfer
await connext.transfer("indra987zxy...", "12.5");

// withdraw
await connext.withdraw();
