Description
How to set up a multisig wallet step by step: a 2-of-3 Bitcoin multisig in Sparrow, then an Ethereum multisig in Safe, with three hardware wallets, no company holding a key and no subscription.
Last week we explained what multisig is. This week we build one. It takes about an afternoon, and once it's done no single lost device, stolen seed or buggy firmware can take your coins.
What we cover:
• What you need: three hardware wallets from three different makers, metal seed backups, Sparrow and Safe
• Using a Trezor as one key (Trezor Suite doesn't create multisig, Sparrow coordinates it)
• Bitcoin: creating a 2-of-3 multisig in Sparrow
• The wallet file (output descriptor) and why two seeds alone can leave you stuck
• Checking the address on the device, a test deposit, and signing with two keys
• The recovery test: delete the wallet and rebuild it from the file
• Ethereum: creating a 2-of-3 Safe, signers, threshold and network fees
• The Safe trap: your Safe only exists on the network you deployed it on
• The Bybit hack and blind signing: what multisig can't protect you from
• The most common multisig mistakes
