# WASM

Web Assembly

The Metaverse.Network also support WASM smart contract via pallet-contracts module, which provides a secure sandbox for deploying and executing WebAssembly (Wasm) smart contracts. 

Developers can utilize any programming language that compiles to Wasm, ensuring it aligns with the pallet-contracts API for compatibility. To streamline development and reduce the need for repetitive coding, the preferred approach involves using a domain-specific language (eDSL) designed for pallet-contracts, like **ink!** (Rust-based), with potential for more options as the ecosystem evolves. 

In this tutorial, you will learn how to deploy the WASM smart contract using [Flipper contract](https://github.com/paritytech/ink/blob/v4.0.0/examples/flipper/lib.rs) with **!ink.** 

Below is a summary of steps in this tutorial

1. Set up !ink environment
2. Build Flipper contract with !ink
3. Deploy using [Polkadot.JS](https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Falphanet-rpc-gcp.bit.country#/contracts)
