What is CosmWasm?

CosmWasm is a blockchain, decentralized application (dApp), and smart contract development framework created by Cosmos for developers building on the Cosmos Network. Leading blockchain ecosystems employing the use of CosmWasm include: Iris Network (IRIS), OKExChain (OKT), Persistence (XPRT), and others. CosmWasm is a WebAssembly-based (WASM) iteration designed to allow software engineers to easily build smart contracts in Rust, Go, or AssemblyScript on multiple chains through the Cosmos Inter-Blockchain Communication (IBC) Protocol interoperability solution. CosmWasm is built for easy integration with Cosmos SDK and as a mature tooling system for smart contract deployment and testing.
