About Project

CosmWasm is a new smart contracting platform built for the cosmos ecosystem. If you haven’t yet heard of it, please check out this intro (opens new window). The purpose of this documentation is to give a deep dive into the technology for developers who wish to try it out or integrate it into their product. Particularly, it is aimed at Go developers with experience with the Cosmos SDK, as well as Rust developers looking for a blockchain platform.

CosmWasm is written as a module that can plug into the Cosmos SDK. This means that anyone currently building a blockchain using the Cosmos SDK can quickly and easily add CosmWasm smart contracting support to their chain, without adjusting existing logic. We also provide a sample binary of CosmWasm integrated into the gaiad binary, called wasmd (opens new window), so you can launch a new smart-contract enabled blockchain out of the box, using documented and tested tooling and the same security model as the Cosmos Hub.
