# Mainnet on Polygon

MainNet on Polygon is the production network for processing tasks in a secure, decentralized, and confidential cloud environment.

Requirements for running a node on polygon:

* MATIC (recommended 10 MATIC/node)
* NETWORK defined into the config file. ( NETWORK=AUTO or NETWORK=POLYGON)
* TASK\_EXECUTION\_PRICE defined 

Config file example:

#### You can either manually update the settings in the config file or just upgrade to the latest git version and run the installer to select the appropriate option for you:

$ cd \~/mvp-pox-node && sudo git pull && ./etny-node-installer.sh

\*\*\* 1. Automatic = This option will set polygon Mainnet if your wallet has MATIC, otherwise will set bloxberg Mainnet (recommended for most users)

\*\*\* 2. Polygon Mainnet (ECLD) = This option will set polygon Mainnet and you should ensure that your wallet contains MATIC for gas fee
