Crypto-wallet Guide

A small guide we put together on different types of cryptowallets

What is a crypto wallet? 🤔

To keep it simple, a cryptocurrency wallet is a piece of software that stores the private and public keys to your cryptocurrency. Cryptocurrency wallets interact with the blockchain to send, receive, and keep track of cryptocurrencies.

How does it work?

Unlike your traditional paper wallet, a crypto wallet only stores private and public keys. Crypto wallets work like a safe, where the private key acts like the combination to gain access inside the safe. Just like you protect important combinations and passwords you should avoid sharing your private keys, to prevent losses of your crypto-assets.
