Multisender Review 2026: A Developer SDK for Token Batches

Multisender is a TypeScript SDK for distributing ERC-20 and native tokens to many wallet addresses in batched transactions on EVM chains. It is aimed at developers building a distribution workflow into an application, rather than people looking for a standalone wallet interface.

The SDK includes recipient-list management, CSV imports, recipient validation, draft reviews, calldata generation, and distribution tracking. It supports Node.js and browser environments, and requires Node.js 18 or later for Node.js use.

An active subscription and API key are prerequisites. Multisender prepares transactions but does not sign or submit them, so users retain control of transaction approval and must check the calldata and recipients before sending.

The SDK connects to Multisender’s service using an API key. Its methods can retrieve supported-chain and project information, manage recipient lists, validate distribution recipients, and create or prepare distributions. Lists can be assembled directly or imported from CSV, and can be reused for later sends.

For a distribution, Multisender prepares transaction calldata for the relevant token and recipients. The single-step flow creates and prepares a distribution in one call; the two-step flow creates a draft for review before preparation. The SDK does not sign or submit the transaction: the user or application must do that on the selected EVM chain.

An active Multisender subscription is required, but subscription prices, distribution-volume limits, and any additional charges are not published here. Check the current plans in the Multisender dashboard before subscribing.

Blockchain transaction gas is separate from the subscription. The user signs and submits the generated transactions, so network gas costs depend on the chain and transactions involved.

Multisender generates transaction calldata but does not sign or submit transactions. Review recipients, token amounts, network, and transaction details before signing; a mistaken or malicious transaction can still result in irreversible losses. API keys authenticate requests and should be stored securely, particularly because the secret is shown only once when created.

Multisender does not publish audit details, information about its security track record, or team details. The product description does not establish the security of its service or smart-contract interactions. Subscription and regulatory details are also not published.

Multisender is for developers who want a TypeScript interface for preparing token distributions to many addresses, especially when they need reusable recipient lists, CSV imports, or a review step before a batch is prepared. It is less suitable for users seeking a no-code transfer interface or a service that signs and submits transactions for them.
