To use our services, you will need a hardware wallet which is a device that stores your private keys offline and can generate a new address for every transaction, protecting both your and your customers’ privacy.
We recommend the Ledger Nano S as an inexpensive option. Get one now. (Affiliate link — helps us out if you order through that link. Thanks!)
Another good option is anything by Trezor.
Both Ledger and Trezor have other products as well, but the ones referenced above are the least expensive options and, used correctly, are just as good as the more expensive options. We help our clients to understand best practices when it comes to wallets. It’s super easy!
Please note: Never buy a hardware wallet from a third party. Order directly from either Ledger or Trezor. Supply chain attacks are uncommon but possible, and ordering the wallet from the manufacturer gives you extra peace of mind.
