Passive income with ETH?

i don't frequent this space but remember reading a couple of comments on reddit about users using their ETH to make passive income through lending (might have been using maker).

Googling leads to a wall of hits that may or may not be scams (ethlend, cryptolend, bitfinex) so i was hoping someone could enlighten me as to the best way to make passive income with eth trustlessly or with low, clear-cut risks.
