Why Use a Metal Seed Phrase Wallet?
A cryptocurrency wallet's seed phrase (usually 12 or 24 words) is the only key to restoring the wallet. If lost or stolen, funds become inaccessible forever. Common storage methods include paper, safes, digital backups, but the most reliable solution is a metal wallet—engraving the seed phrase on metal plates resistant to high heat, water, and corrosion, completely isolating it from cyber attacks.
