# Unification Mainchain Documentation

Welcome to the documentation for Unification's Mainchain. These docs cover how to build and install the und application, how to run a node on MainNet, TestNet and DevNet, and how to interact with the Mainchain network.

IMPORTANT!

If you are upgrading your und binary from a previous version to v1.8.x, Cosmos SDK v0.46.x uses a new keyring interface, and your keyring will be migrated the first time you interact with the upgraded und

Please ensure you back up your keystore first, and make sure you have safely copied private keys and written down mnemonics!

On Linux systems, for example, the keyring may be located in

$HOME/.local/share/keyrings/UndMainchain.keyring

Safely backup your keyring and any keyfiles you may be using!
