Excessive payout list of addresses _payoutEth would lead to a revert. Rendering users unable to receive eth
use of .transfer() may revert if the recipient’s fallback function consumes more than 2300 gas. This may lead to a revert leading to recipients unable to recieve their payout.
The .transfer() function intends to transfer an ETH amount with a fixed amount of 2300 gas. This function is not equipped to handle changes in the underlying .transfer() functions which may supply different amounts of gas in the future. Additionally, if the recipient implements a fallback function containing some sort of logic, this may inevitably revert, meaning the vault and owner of the contract will never be able to call certain sensitive functions.
Consider using .call() instead with the checks-effects-interactions pattern implemented correctly. Careful consideration needs to be made to prevent reentrancy.
