What is Self Custody ?

One of Bitcoin’s value propositions is that it’s a digital bearer asset. You do not need to trust 3rd parties to keep your Bitcoin safe on your behalf. Only through self custody does Bitcoin guarantee protection against censorship and confiscation.

Think of Bitcoin like a dollar bill, if it’s not in your physical control, you don’t own it.

Equipment List

In order to follow along with this guide and create a robust self custody setup, you’re going to need some equipment.

  1. A Coldcard Hardware Wallet
  2. A SeedPlate
  3. At minimum 2 MicroSD cards for encrypted backups.

The two MicroSD cards are meant to be used for encrypted backups.

Purchase a inexpensive Microsd card to use only for interacting between your Coldcard and your computer.

This is the safest way to use the Coldcard because you don’t ever need to directly connect the Coldcard to an internet connected device.

Step 1 –  Acquire Bitcoin

KYC

An important consideration when choosing how you will acquire Bitcoin is KYC.

KYC stands for ‘Know Your Customer’, it is a regulation that any businesses with a banking relationship has to abide by, including Bitcoin exchanges.

These rules are imposed worldwide and are geared towards ensuring that a business acting as a money exchange and/or transmitter has ‘suitable’ information on every customer they serve.

KYC comes with potential risks

  • KYC information ties your personal identity to any Bitcoin you purchase. Since the Bitcoin ledger is transparent, this poses privacy concerns for users.

 

  • The potential for your private data held by these centralized entities being compromised carries privacy and security risks for you.

 

  • Censorship

 

  • Confiscation ( only if you don’t self custody ! )

NO KYC

You can choose to acquire Bitcoin in a more private way by using Peer to Peer services and software. This does not require you to give up your personal information in exchange for the privilege to buy Bitcoin.

Common payment methods include bank transfer, cash deposited in the seller’s bank account, in-person cash (face-to-face) trades as well as payment networks such as Zelle, Alipay, even Cash App and PayPal.

Step 2 –  Setup A Hardware Wallet

Generate a 24 word seed (wallet)

A passphrase ( sometimes referred as the 25th seed word ) is a user defined addition to the seed. Using a word or group of words adds another layer of security on top of your 24 word seed.

This additional layer of security prevents someone with your 24 word seed to be able to access the wallet.

Always store the passphrase SEPARATE from the 24 word seed.

Step 3 –  Backup Seed Words On Steel

Backing up seed words onto steel provides protection against extreme conditions.

This includes being waterproof, fireproof up to certain thresholds, shockproof, as close to indestructible as possible.

Always store the passphrase SEPARATE from the 24 word seed. If you store the seed words and passphrase together, it becomes a central point of failure.

By separating the two, you create an additional layer of security for your Bitcoin wallet.

Step 4 –  Create Encrypted Backups

The MicroSD encrypted backups should never be exposed to an internet connected device unless you need access to your wallet information in the case of an emergency.

The best way to use the MicroSD card in an emergency, would be in a new Coldcard device, isolated from any internet connected devices.

The only other time encrypted MicroSD backups should be interacted with are during your annual checkups. You will attempt to restore the wallet on a Coldcard to verify it’s still viable.

You want to separate backups for security reasons. If all the backups are in 1 location and it gets compromised, your shit out of luck.

Step 5 –  Choose A Software Wallet

In order to use the hardware wallet (Coldcard) to receive and send Bitcoin transactions, a watch only wallet is exported from the Coldcard to the software wallet.

A software wallet acts as a bridge between the Bitcoin network, and the wallet created and secured on the Coldcard.

Specter Wallet is the easiest way to setup a private Bitcoin full node and use a software wallet that seamlessly interacts with many hardware wallets.

If you want to have maximum security and privacy – using specter is the way to go.

Step 6 – Test & Verify

Open  your wallet to find an unused Bitcoin address

Address explorer is a feature the Coldcard wallet offers to make sure your are depositing to a Bitcoin address that belongs to your wallet.

This gives you confirmation that the address you are being shown in the wallet software is an address you control, and not generated by malware/virus on your computer.

Congratulations

Make sure you go back and check on your backups at a set interval of time – a few times a year is good practice. You want to be comfortable restoring your backups should the need arise.
