Its a smart contract/ actor to facilitate sending the amounts to multiple addressess in a single transaction saving on gas cost.
When we have to repeat multiple transactions of same nature, we would prefer a way to save on the gas cost by bunching together the actions. This smart contract is designed to do send amount to multiple addresses in a single transaction. By taking complete transation information such as recipients' addresses and amounts to send, we can repeat the transfer logic in a single transaction.
The smart contract is written in solidity and tested in remix environment on Hyperspace testnet. It is just a learning step to use the filecoin testnet as any evm testnet. More need to be explored in terms of how native filecoin actors can be used to solve use cases related to decentralized storage.
