# What is Swisstronik?

Swisstronik is a layer 1 solution built on the Cosmos SDK framework. It aims to combine the benefits of the Ethereum Virtual Machine (EVM) with the underlying infrastructure provided by the Cosmos SDK. This integration allows Swisstronik to offer Ethereum compatibility while providing additional features such as private EVM execution using Intel SGX.

## Why Cosmos SDK?

Cosmos SDK serves as the foundation for Swisstronik, providing essential components for the consensus and networking layers of the blockchain.

1. **Scalability**: The Cosmos SDK allows developers to optimize specific components of their blockchain application, enabling efficient handling of increasing transaction volumes without compromising performance or security.

2. **Interoperability**: With the Cosmos SDK, developers can integrate functionalities and smart contracts across interconnected blockchains using [Inter-Blockchain Communication (IBC)](https://tutorials.cosmos.network/academy/3-ibc/1-what-is-ibc.html), facilitating collaboration and expanding the possibilities for decentralized applications. This feature will be implemented in Testnet 2.0.

3. **Security**: The Cosmos SDK incorporates the battle-tested Tendermint consensus algorithm, ensuring that transactions and data on the Swisstronik blockchain are validated by a network of trusted validators.

## EVM-Module

Swisstronik incorporates an EVM-Module as its application layer, enabling developers to leverage the Ethereum Virtual Machine and seamlessly utilize the same tools available in the Ethereum ecosystem such as [Hardhat](https://hardhat.org/tutorial), [Solidity](https://docs.soliditylang.org/en/v0.8.20/), [EthersJS](https://docs.ethers.org/v5/), [Web3.js](https://docs.web3js.org/), etc.

This compatibility ensures that you can write smart contracts and develop decentralized applications on Swisstronik using the same tools and languages you are already familiar with from Ethereum. It also facilitates easy migration of existing Ethereum smart contracts to the Swisstronik blockchain, promoting code reusability and streamlining the development process.
