So, you've created a seed phrase. What should you do now? Well, the first step is to write it down somewhere safe. Your seed phrase should be both fireproof and waterproof. Alternatively, you could also engrave it on a metallic plate. Manufacturers such as Trezor or Ledger make devices like this for this purpose. However, if you can't be bothered to invest in such a device, you can always use a paper wallet. It is, however, better to know how to get private key from seed phrase.
