Onramper is a real company, founded in Amsterdam in 2019 and operated by Onramper B.V., and its widget is embedded by well-known wallets. It is not a scam. It is also not what many searchers assume: it is not an exchange, not a money transmitter and not the seller of your coins. Its own documentation says it is not involved in the transaction between you and the on-ramp. Every order is filled by a partner such as Transak, Banxa or MoonPay, and it is that partner's license, verification and compliance that apply.
That is why the legitimacy question is really about the route. If Onramper sends you to a licensed U.S. on-ramp, you are dealing with a licensed U.S. on-ramp. If it sends you to a partner that is thin in your state, you are dealing with that. Onramper's small Trustpilot profile, under 2 out of 5 from fewer than twenty reviewers, is dominated by people who could not get an answer after an order stalled, which is a support problem rather than a fraud problem, but it is the problem to weigh.
