Paper Wallet
A Paper Wallet is very simple. You write down your seed phrase on a piece of paper as a way to remember it and every time you initiate a transaction you have to manually enter your seed phrase. This requires you to store that paper somewhere safe that only you have access to.
Remember, if someone finds that paper they can steal your money, and if you lose it you will lose all your money. Make sure you store it safely where no one would find it.
