Carbon

Carbon is a decentralized cross-chain financial protocol built atop of Cosmos-SDK. Engineered by Switcheo Labs, Carbon is designed specifically to support scalable and secure trading of derivatives and sophisticated financial instruments such as options, futures and bonds.

Carbon also acts as a building block for cross-chain DeFi by bridging the Cosmos and Ethereum ecosystems, allowing for cross-chain money markets and permissionless listing of tokens from IBC, EVM and non-EVM chains.
