Some tokens contracts like USDT don't comply with the erc20 standard, the transfer() doesn't return a boolean. https://github.com/code-423n4/2022-09-frax/blob/55ea6b1ef3857a277e2f47d42029bc0f3d6f9173/src/frxETHMinter.sol#L199
Use the safeErc20 library from OpenZeppelin.

Not really medium risk. Technically you could use safeTransfer, but if someone were to accidentally send something to this contract, it would most likely be either ETH, FRAX, frxETH, or sfrxETH, all of which are transfer compliant.
