# Supported Hardware

{% hint style="warning" %}
Hardware requirements can be changed during upgrades, therefore please check this page before upgrade
{% endhint %}

Swisstronik uses Intel SGX to protect user transactions and smart contract state. Since Intel SGX is a hardware solution, you should have appropriate hardware to run it. On Testnet stage we have tolerant requirements, but closer to mainnet we will significantly increase them to have production-grade security

### Hardware requirements:

* For now, you can use any **Intel CPU** which supports **SGX via SPS** and EPID remote attestation
* 32GB RAM
* 500 GB SSD

Just because an Intel SGX feature is supported in CPU does not mean that is enabled in the BIOS. Please check if it is enabled in BIOS
