2. Decide How Many Signatures You Need

Choosing signature requirements impacts security and usability. The most common setup is 2-of-3 multisig:

• Balance: Good mix of security and ease of use
• Backup: You can lose one key and still access funds
• Flexibility: Various setups possible

Quick comparison:

Setup	Required Signatures	Total Keys	Use Case
1-of-2	1	2	Personal backup
2-of-3	2	3	Most individual/small business users
2-of-4	2	4	Shared wallets with backup
3-of-5	3	5	Large organizations

3-of-5 isn't always best:

1. More complex to manage
2. Costlier (more hardware wallets)
3. Slower transactions

"The most common way that people lose bitcoin when self-custodying is by introducing too much complexity."

For most, 2-of-3 hits the sweet spot:

• Store keys in different locations
• Access funds if one key is lost
• Easier to manage

Remember: More keys = more security but also more complexity.

3. Choose and Set Up Hardware Wallets

Hardware wallets are crucial for multi-signature setups. They store private keys offline, boosting security.

"The order and spelling of the seed phrase words matter, but capitalization does not. Users should take their time to carefully write down each word in the correct order."

Each cosigner needs their own hardware wallet and unique recovery phrase. Follow steps carefully to secure shared funds.

4. Create and Safely Store Seed Phrases

Creating and storing seed phrases is vital. Each cosigner needs a unique seed phrase kept secure.

Steps:

1. Generate the seed phrase Your hardware wallet or software will create a 24-word phrase.

2. Write it down correctly

   • Read from device screen
   • Write on paper with pen
   • Double-check each word
   • Make a pencil backup

3. Verify your seed phrase Confirm by entering specific words in order.

4. Choose a secure storage method

Paper	Easy, cheap	Fire/water vulnerable
Laminated paper	Water-resistant	Ink may degrade
Metal plates	Fire/water-resistant	Pricier
Encrypted USB	Digital backup	Data corruption risk

5. Secure your backups

   • Use fireproof safe or safety deposit box
   • Consider tamper-evident bags
   • Spread copies across secure locations

6. Never store digitally Avoid cloud storage, email, password managers, phone notes.

7. Plan for emergencies Create access protocol for trusted individuals.

"Your bitcoin backup is your bitcoin. In a 2-of-3 setup, you can afford the loss/theft of one signing device and still be able to spend your bitcoin."

5. Set Up the Multi-Signature Wallet

Now, set up your multi-signature wallet:

1. Choose a wallet provider (e.g. Sparrow Wallet)
