CosmWasm

    Cosmos created CosmWasm, a blockchain, decentralized application (dApp), and smart contract development framework for developers working on the Cosmos Network. Iris Network (IRIS), OKExChain (OKT), Persistence (XPRT), and others are among the leading blockchain ecosystems that use CosmWasm. CosmWasm is a WebAssembly-based (WASM) iteration that enables software engineers to build smart contracts in Rust, Go, or AssemblyScript on multiple chains using the Cosmos Inter-Blockchain Communication (IBC) Protocol interoperability solution. CosmWasm is designed to be a mature tooling system for smart contract deployment and testing, as well as for easy integration with the Cosmos SDK.
