# Wasmbindings

### Core Concept

**WASM Bindings** (WebAssembly bindings) are interfaces that allow CosmWasm smart contracts to interact with **native blockchain modules** beyond the standard Cosmos SDK bank and staking modules. They provide a bridge between WebAssembly smart contracts and the underlying blockchain's specialized functionality.

We currently only support queries for our custom modules.
