Osmosis is Layer-1, Proof-of-Stake (PoS) blockchain built using the Cosmos SDK that has optimized its design to be a sandbox for automated market makers (AMMs). The chain enables developers to design and deploy customized AMMs by using its various modules and leveraging Osmosis' on-chain governance system. Osmosis' native token, OSMO, grants holders the right to vote on proposed network changes and earn rewards for helping secure the network. Its first application, also called Osmosis, is an AMM that features ATOM and OSMO as its initial base trading pairs.
