I want to make one dapp in order to transfer many ERC20 tokens at once. Many people still do this manually, one transaction at a time. 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.

Hello, i'm a solidity and Dapp developer, i have a solution like that, works like the one you want to clone but much more simpler interface, you can upload a csv with 100 addresses and amounts, and execute the transfer using metamask. Please send a message for more information
