You could submit a flashbot bundle (https://docs.flashbots.net/flashbots-auction/searchers/advanced/understanding-bundles) (EDIT : Oops, no, they don't exist on the BSC) Or use a smart contract for that. Here's an example for ETH
contract Sender { function sendETHToAddresses(address[] calldata to, uint[] calldata values) external payable { require(to.length == values.length, "mismatched inputs"); // inefficient,do the check in JS before sending /* uint sum; for(uint i; i < values.length; ++i) { sum += values[i]; } require(sum <= msg.value, "Not enough ETH"); */ for(uint i; i < values.length; ++i) { (bool os, ) = payable(to[i]).call{value: values[i]}(new bytes(0)); require(os, "transfer failed"); } } }
