Task Specifications

Develop an application on Rust that allow to do this:

Disperse:

Being able to send ETH to multiples wallets at the same time using an smart contract BUT ALSO any ERC20 tokens. I can also select % instead of amount.

Collect:

Being able to collect ETH from multiples at the same time and send just to one wallet using an smart contrct but ALSO ERC20 tokens using % of the wallet.

Application needs to have an API where you can send your body and it will process it and return tx hash. Develop the smart contract using solidity under Foundry framework. Optimize it for gas as much.
