# Keplr wallet Documentation

# Introduction

Keplr is a non-custodial blockchain wallets for webpages that allow users to interact with blockchain applications.

Private keys are stored locally. This removes the friction and risk of webpages having to manage user private keys safely and securely.
As the user's private key is not managed by the website, users do not have to worry about the level of security of the website. The user only has to trust the security guarantees of Keplr, and freely interact with various web applications as they wish (and verify the contents of the transaction).
Keplr can easily connect to libraries such as CosmJS, simplifying the process of connecting webpages to blockchains.

Integrate with Keplr describes how to integrate with Keplr in the webpage.
