No. One of the core features of ONCHAIN® Ramp is that it abstracts gas from the buying experience. That means you don’t need to first acquire ETH, BNB, SOL, or any other gas token just to buy the digital asset you actually want.
Instead, ONCHAIN® Ramp allows you to purchase your intended asset directly—in one step. The complexity of managing gas tokens is handled behind the scenes, so you can focus on what you came for: getting the token you want, not the token you need just to get there.
That said, network gas fees still apply, as with any on-chain transaction. These fees are clearly shown during the order review step, so you’ll always know exactly what you're paying before you confirm.
In short: you may still pay gas, but you won’t need to think about gas.
