BatchSend

With our BatchSend, users can enter CSV (addresses, the specific amounts for each address) and send tokens in a single transaction. The tool can be used on initial token distributions and airdrops. To use the app, users should connect their MetaMask wallets, specify the ERC-20 Token contract address and once they enter the CSV; approve and confirm the transaction. The users can also see their balances once they have connected their wallets. The project is deployed on the Filecoin Hyperspace testnet.

We have created a smart contract in order to send tokens to multiple addresses on a single transaction. The contract takes the input values that are in CSV and sends the specified ERC-20 tokens for each address. Thanks to the smart contract, users are able to send to multiple addresses on a single transaction. On the front end, we implemented Metamask as the wallet service to connect with our app and created a unique design. We used ethers.js library to connect the smart contract and Metamask. We also used Filecoin Hyperspace testnet; deployed an ERC-20 token to test the app.
