Self-Custody: How to Secure Your Bitcoin

Don’t trust, verify!

Exchanges, other people or certain wallets may promise to protect your bitcoin, but the truth is, the only person who can protect your bitcoin is you.

Here are some ways you can verify your BTC is secure: 🧵👇

Create & control your keys.

Storing BTC on an exchange is technically storing them in someone else’s custody. Self-custody begins with creating your own keys.

Shared custody could be useful for businesses or families if secured through multisig or Shamir backup. 1/

Generate & keep your seed offline.

The risk of interception or observation is high if you create a seed online.

Use your Trezor hardware wallet to generate your seed offline and store it on paper or steel using Cryptotag Zeus plates or Cryptosteel capsules. 2/

Use a passphrase.

Backup your back up with a passphrase. This extra layer of protection keeps your bitcoin safe even if someone finds your seed or your device.

Keep in mind that your passphrase is space and case sensitive. 3/

See for yourself.

Promises and certificates of security are not enough - make sure that you can see how a company or device’s security is achieved.

Trezor’s hardware and firmware has always been completely open source so users can verify everything themselves. 4/
