CosmWasm is a set of Rust crates providing the standard library for writing WebAssembly smart contracts on Cosmos SDK blockchains. It enables secure, type-safe, multi-chain smart contract development with native IBC interoperability.
Use cases
- write smart contracts for Cosmos blockchains in Rust
- build cross-chain dApps using IBC
- develop secure DeFi protocols resistant to reentrancy attacks
- generate JSON schemas for smart contracts
- verify and check compiled wasm contract blobs
- unit and integration test smart contract business logic
When to choose
- you are building smart contracts on Cosmos SDK chains
- you need native inter-blockchain communication via IBC
- you want Rust's type safety and testing tooling over Solidity
- you need multi-chain contract deployment from one codebase
When to avoid
- you are targeting EVM/Solidity chains like Ethereum
- you need contracts outside the Cosmos ecosystem
- you want a high-level language other than Rust for contract development
