Token Multisender Dapp smart contract. Airdrop tokens. Batch sending ERC20, ETH, Ethereum tokens. Send thousands of transfers in a few transactions. It can help user to save more tx fee and time than sending one by one

Problem:

Previously in Ethereum Network, additional tools were required in order to transfer many ERC20 tokens at once. Many people still do this manually, one transaction at a time. This process is time consuming and prone to an error.

Solution:

This Dapp allows a user to send thousands of token transfers in a very effecient way by batching them in groups of 145 token transfers per Ethereum transaction. This automation saves time by automatically generating transactions to MetaMask. Finally, this tool allows a user to maintain security of their account by delegating the trust of their private keys to a secure MetaMask wallet.

How to use:

1. Install Metamask.
2. Make sure you have an account in MetaMask which has a token balance.
3. Make sure your MetaMask is pointed to the network that you would like to use.
4. Make sure your MetaMask account is unlocked.
5. Go to https://rstormsf.github.io/multisender/#/
6. Wait for the full page to load.
7. Select a token from the dropdown that you would like to send.
8. Provide either JSON or CSV text in the textarea (see example below).
9. Click next.
10. If everything looks good, click next once again.
11. Wait for MetaMask to generate an approval transaction.
12. Once the approval transaction is mined, MetaMask will generate as many transactions as needed for your token transfers (145 addresses per tx).
13. Done!

You can test this tool on any test network, if you want to make sure that everything will work as expected.

How to setup dev environment

1. git clone [email protected]:rstormsf/multisender.git
2. cd contracts
3. I used node -v v9.7.1
4. npm install
5. deploy MultiSender contract OR use existing deployed version: 0xa5025faba6e70b84f74e9b1113e5f7f4e7f4859f currenty deployed on Kovan, Rinkeby, Ropsten, POA-network, POA-Sokol, Mainnet Instructions on how to deploy it is listed below.
6. cd ..
7. npm install
8. cp .env.example .env
9. open .env file and provide an address of multisender contract
10. npm run start

Contract Deployment

There are 2 ways to deploy the contracts: Upgradable and non-upgradable way. Non-upgrdable:

• cd contracts
• npm run flatten
• take flats/UpgradebleStormSender_flat.sol and deploy it using https://remix.ethereum.org/
  • select solidity 0.4.23 version in settings
• once deployed, call initialize function with parameter address of owner's contract

Disclaimer

This tool is not affiliated with https://poa.network This is a personal project of Roman Storm.

He is not responsible for any loss from transactions derived by MultiSender. Some of the underlying JavaScript libraries and Ethereum tools that were used are under active development. The website and smart contract has been thoroughly tested, there is always the possibility something unexpected happens resulting in losses of Ethereum and/or tokens.

Any ERC20 tokens you transfer to the Multisender will be sent out to the addresses that you provided.

The smart contract source code can be audited by anyone in this repository.

I encourage you to assess its security before using the Mutlisender Dapp.

multisender's Issues

Add APIs for testnets

Proper structure

1. Integrate travis-ci or circleci
2. Write unit test and end-to-end test
3. Integrate netlify for predeployment's PR previews

Allow WalletConnect integration

Is there a reason one cannot connect their wallet using WalletConnect? Would be great to have that integrated

How to setup project in local environment

Hello Sir, it is an interesting project, could you kindly add a installation guide when you have free time? Thanks.
I tried to setup this project in my laptop but failed at the compiling the contracts.

Add localStorage support

Problem:
When navigating thru routes, multisender will still run a job that was asked previously such as recursive functions or setTimeout.

Solution:
If a route was changed from
/#/4 to /#/1
it should cancel out all processes and start everything again by cleaning up all data in it.

However if navigating from #/1 to #/3 - it should keep the state by storing it in localStorage, not JS mobx state.

How specifically does this save on gas?

How long did it take to succeed?

How long did it take to succeed? (145 transfer)

Incorrect amount sent

I have tried to send USDT to 2 addresses using multisender and it screwed up decimals.
Instead of sending 50 USDT, it sent 5k USDT and instead of 233 USDT it sent 23k...

It showed correct amount in the UI and also for allowance but in the end, it just pulled more from my wallet.

multisend problem

Good morning,

I have sent the ANG token to more than 5000 addresses:
https://etherscan.io/tx/0x43db3eec14796721a34edba3d37ae4c250a5ad4fcfcd312740d4016fedb70169

For this transaction more than 3 ETH were charged and actually deposited in your address:

For some reason the mutisend seems to be stuck. Can you please verify what is going on?
Thank you

out of gas error when sending erc1155 batch tx

Hello,

I've tried to use the contract to do an erc1155 airdrop, but have encounter a problem.
We used this contract before and it was working fine so I assume this is link to the Berlin update

Opcode: [DELEGATECALL]
Error Message: out of gas

1. Is this a know issue?
2. Do you plan to fix this?
3. If yes, when?
4. If no, do you know any other solution I could use?

Thanks a lot!

gas required exceeds allowance

I follow the instruction .

1. deply the contract flats/UpgradebleStormSender_flat.sol
2. invoke initialize method
3. approve to contract

then I invoke multisendEther or multisendToken method and get the error as title describe.
Please give me some help :)

Second tx does not appear after approve tx is confirmed

I am testing Multisender on Rinkeby.

I have created a multisend with 3 recipients, transferring 1 DAI to each.

I am using Frame + Aragon Agent (a smart contract account).

I have passed a proposal in my Aragon organization to confirm the approval tx:

However the Multisender dapp does not ever send the second tx needed to complete the transfer, and it gives me an error message suggesting I contact support:

Any idea what might be going wrong here?

Not a number: 2,647,733.007

if metamask native eth balance is big like: 2,647,733.007 eth, it doesn't work when user navigates to second screen.

Sending multiple ERC721 tokens to an address.

1. We should either be allowed to enter multiple addresses to send
2. or multiple token IDs separated with commas.

I want to send 65 NFTs to the same address. 103 to another, 1 to another, 30 to another. I want to send the NFTs randomly from my address, but I can make a CSV myself, that is easy. I can just pick out Token IDs randomly.

But the main issue is stated above. I should be able to send more than one NFTs to the same address.

This is on Avalanche Network C-Chain by the way.

TypeError: window.Web3 is not a constructor

Getting this error after npm run start in the last step. I can see the MultiSender screen for one second then I get the error. I have used nvm to use the same version of Node.js during installation as the author.

(anonymous function)

151506 | // Checking if Web3 has been injected by the browser (Mist/MetaMask)
151507 | if (typeof web3 !== 'undefined') {

Unable to use it with multisig

Hello,
I want to add multisendToken transaction to multisig contract.

However when I confirmed the transaction in the multisig contract, and the multisendToken got executed but it also got reverted.

Do you know why? This is the transaction: https://kovan.etherscan.io/tx/0x4a72d6a70e25bb53da862d388dda85d5778f29ac9061af82e6919add7af8c727

ETH转账问题请教

你好。打扰了，我有个问题想请教一下。我现在有一个以太坊私钥，很多年前的。导入okex钱包后可以看到里边的余额，但无法交易，咨询了客服，告知我我这个是ETH分叉之前的老地址，不支持地址重放保护机制，所以无法转账，建议我找一个没有这种保护机制的小钱包尝试一下。请问对这些有了解么，可以付费解决，打扰您了，谢谢

Can you guys make it run over the KCC (kucoin community chain).
Thanks guys

Add repeat tx hash

if for some reason tx failed, as a user, I should be able to insert a tx hash and repeat it again.

How to do it?

1. Validate tx hash
2. Check status, if it was successful, just offer user to execute it
3. if status was 0x1 which means failed, try to see if

• it was out of gas by checking if gasLimit == gasUsed in that txHash. If so, increase gasLimit and offer to resubmit
• if it was multisend ether, maybe the reason was not enough eth balance at the time of execution.

There is pending PR #2 which hasn't been tested fully and maybe it could be reused.

multi-send ERC20 token not work

I use it, I thought it called the transfer function, but called the approve function, this is not my purpose

Metamask(4.9.3) is not working

Metamask version 4.9.3 is not working with RPC Error.

Transfer transaction may fail when chain reorgantzaion happens

In usual cases, there are two transaction we need to send to use multisender.
The first one is to approve tokens for multisender contract and the second one is to actually do the transfer.

However, cases can happen where chain organization happens when approve transaction is reverted, but multisender has already make user send the second transfer transaction at this time, which will definitely fail because tokens are not approved.

This will cause users to lose transaction fee for transaction failure.

"NaN ETH" values on VIP tab

There value stated to buy VIP access is "NaN ETH", believe this to be wrong. Link to site is here

Refer to screen capture below

On BSC very large gas limit

try to send USDT to 4 address but get error "Insufficient BNB balance on your account Please have at least 0.5 BNB"
Transaction Fee for one simple transfer is 0.0005 BNB

add ETH multisend function

Besides ERC20 multisend, we need to also add multisendEth on contract and on front end side

Add statistics

Every tx emits an event Multisended
Collect all events, calculate all token balances, write a nice UI that shows how much total token transfers has been transferred using this tool.

setting up the project on gitpod

Hi, I have a similar project to work on currently I can't get it running on gitpod. I can share the workspace with you, it basically gives error with node-gyp error and can't run npm install. If you can help to set it up, it will be awesome. Thanks
