Token BulkSender

This DAPP was used to send token or ETH to many addresses in one transaction, and that can help user to save tx fee

Demo

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 1–200 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:

Install MetaMask. Make sure you have an account in MetaMask which has a token balance. Make sure your MetaMask is pointed to the network that you would like to use. Make sure your MetaMask account is unlocked. Go to https://bulksender.app Wait for the full page to load. Select a token from the dropdown that you would like to send. Provide either EXCEL or CSV or TXT file with addresses and values. Click next. You need to approve a enough amount to our contract. Once the approve transaction is complete, click Next, go to the sending list, and click send, MetaMask will automatically generate a transaction for your token (200 addresses per transaction). Done!

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