Multisend ERC20 tokens and Ether airdrop smart contract

I want to share the MultiSend contract I’ve developed:

This contract has methods to efficiently send ERC20 or Ether to many recipients at once.
It does not enforce any fee by itself, so you can safely use it in your own project as is, saving $100+ on the deployment fee.

The contract code is based on the OpenZeppelin contracts and open source. You are free learn, copy and use it in your own projects as you wish :slight_smile:

Currently, it is used in two of my projects:

  1. WordPress Ethereum Wallet plugin for the admin fee feature implementation, and
  2. The MultiSend app to efficiently airdrop ERC20 tokens or Ether to many recipients at once

Hi @olegabr,

Thanks for sharing :pray:

transact to MultiSend.multiTransfer_OST errored: Error encoding arguments: Error: expected array value (argument=null, value=“0xAb8483F64d9C6d1EcF9b849Ae677dD3315835cb2”, code=INVALID_ARGUMENT, version=abi/5.1.2) getting this error

if i want to use bep20 token, which one should i use, multitransfer_ost. i am having a hard time. can you plz tell me the right way.

Use multiTransferTokenEqual_71p for equal amounts token transfers, and
multiTransferToken_a4A for non-equal amount transfers.

Here you can find javascript code that uses it:
