Losing access to your Bitcoin wallet can be a stressful experience; This guide details the crucial information needed for recovery, acting as a ‘recovery data sheet’. Important: Treat this information with the utmost security – it’s the key to your funds!
Understanding Wallet Recovery
Bitcoin wallets don’t actually store your Bitcoin. They store the cryptographic keys that allow you to access and spend your Bitcoin on the blockchain. Recovery revolves around regaining control of these keys. Different wallet types have different recovery methods.
Types of Wallets & Recovery Methods
- Custodial Wallets (e.g., Coinbase, Binance): Recovery relies on the exchange’s account recovery process – typically email, SMS, and security questions. Document all associated email addresses, phone numbers, and answers.
- Software Wallets (e.g., Electrum, Exodus): These use a Seed Phrase (12-). This is the most common recovery method. Never share your seed phrase with anyone!
- Hardware Wallets (e.g., Ledger, Trezor): Also use a Seed Phrase, but it’s generated and stored offline on the device, enhancing security. Keep the device and seed phrase safe.
- Paper Wallets: Contain both the public and private keys printed on paper. Store the paper securely and protect it from damage.
Essential Recovery Data Sheet Information
Create a secure document (preferably offline) containing the following. Do not store this digitally on easily accessible devices.
Wallet Type
Wallet Name: (e.g., Ledger Nano X, Electrum)
Wallet Version: (e.g., 4.3.2)
Date of Wallet Creation: (Approximate date)
Seed Phrase (If Applicable)
Seed Phrase (12/): (Write it down exactly as it appears, including capitalization and spacing. Consider using a metal backup.)
Seed Phrase Generation Method: (e.g., BIP39, SLIP39)
Passphrase (Optional): (If you used a passphrase, record it securely. This adds an extra layer of security.)
Custodial Account Information (If Applicable)
Exchange Name: (e.g., Coinbase)
Email Address: (Primary email associated with the account)
Backup Email Address: (If any)

Security Questions & Answers: (Document these carefully.)
Hardware Wallet Information (If Applicable)
Device Model: (e.g., Ledger Nano S Plus)
Firmware Version: (Check the device for the current firmware version)
PIN Code: (Do not record this! This is for access, not recovery.)
Seed Phrase Location: (Where you stored the seed phrase backup)
Transaction History (Optional, but helpful)
Recent transaction details can help verify wallet ownership during recovery. Keep a record of:
- Date of last transaction
- Amount of Bitcoin sent/received
- Transaction ID (Hash)
Security Best Practices
- Never share your seed phrase or private keys with anyone.
- Store your recovery data in a secure, offline location.
- Consider using a metal seed phrase backup for durability.
- Regularly review and update your recovery information.
- Be wary of phishing attempts.
