To stake Osmosis, you first need to get it. A fast and convenient way to get OSMO is to buy ATOM on centralized exchange first and then swapp one to OSMO using Osmosis DEX. ATOM is a native token of the Cosmos network as well as OSMO is a native token of the Osmosis network.
The guide below shows how to do all of that using Keplr wallet, OKex centralized exchange and Osmosis decentralized exchange in sequential order.
