The Multisender SDK is an npm package for distributing tokens to many recipients in batched on-chain transactions. Configure your API key below to start using the sandbox.
Overview
Multisender SDK provides a simple TypeScript API for sending tokens to hundreds or thousands of wallet addresses in a single flow. It handles batching, transaction submission, and status tracking automatically. To get started you need an active Multisender subscription and an API key.
Prerequisites
Node.js 18+, npm/yarn/pnpm, and an active Multisender subscription.
Installation
npm
Yarn
pnpm
Bun
npm install @smart_ex/multisender-sdk
Multisender SDK
An npm package (@smart_ex/multisender-sdk) that wraps the Multisender REST API. Install it in any Node.js or browser project to create distributions, manage recipient lists, and query chain/token catalogs.
API Key
A secret token that authenticates your requests. Generate one from the Multisender dashboard under Project Settings → API Keys. Keep it private — anyone with your key can create distributions on your behalf.
Project
Your Multisender workspace. A project holds your API keys, subscription plan, distribution history, and recipient lists. Each API key is scoped to one project.
Base URL
The API endpoint the SDK connects to. Defaults to the Multisender production API. Override it for local development or staging environments.
