Metal Backup
A metal backup is a durable metal plate or device engraved with a cryptocurrency wallet's seed phrase, providing fireproof and waterproof protection for offline key storage.
What Is a Metal Backup?
A Metal Backup is a durable metal plate or device that stores a cryptocurrency wallet's seed phrase through engraving or punching. It protects the seed phrase from fire, water, and physical damage. Users also call it a steel backup, fireproof backup, or seed plate.
To create one, generate your wallet's seed phrase, typically 12 to 24 words from the BIP39 standard. Engrave or punch these words onto the metal using tools like letter stamps, lasers, or DIY kits. Some products provide tile systems where you insert letter tiles into slots. Store the completed backup in a safe location away from your primary wallet.
Metal backups matter because they secure recovery access to your crypto assets. Lose the seed phrase, and your funds vanish forever. Paper backups degrade or burn easily, while digital copies risk hacking. Metal withstands temperatures up to 2500°F, submersion, corrosion, and crushing, ensuring long-term reliability.
Key characteristics include materials like stainless steel or titanium for rust resistance. Types vary: punch-style for manual entry, laser-etched for precision, or modular tiles for error-proof assembly. Choose based on seed length and security needs. Examples include devices supporting multiple wallets on one plate.
A backup in cryptocurrency is a secure copy of a wallet's seed phrase or private keys. It enables recovery of funds if the original wallet is lost or damaged.

Example 1: Hardware Wallet Setup
Alice sets up her Trezor wallet. She writes the 24-word seed phrase on paper first. Then, she punches it onto a stainless steel plate using a CryptoSteel device. She stores the metal backup in a home safe.
- Tool: Letter punch kit
- Benefit: Withstands fire up to 2500°F
Example 2: Disaster Recovery
Bob's house floods. His paper seed backup dissolves. His titanium seed plate, engraved with a laser, survives submersion. He imports the seed phrase into a new Ledger wallet and recovers $50,000 in Bitcoin.
- Scenario: Natural disaster
- Key trait: Corrosion-resistant material
Example 3: Multiple Wallets
Charlie manages three wallets. He uses a Billfodl metal backup with modular tiles. Each wallet's 12-word seed gets its own row on the plate. He secures it in a bank vault.
- Feature: Supports 200+ characters
- Use case: Family or portfolio backup
Example 4: DIY Engraving
David buys blank stainless steel and stamp tools. He engraves his Electrum wallet's BIP39 seed phrase manually. This low-cost method creates a fireproof backup without buying a branded product.
- Method: Hand stamping
- Cost: Under $50
