Product Information

A Bitcoin seed signer is a type of software or hardware tool that is used to sign transactions on the Bitcoin network. In order to sign a transaction, a user must have access to the private key associated with the address from which they wish to send funds. A seed signer uses the user’s seed phrase (a sequence of words that can be used to generate the private key) to sign the transaction, rather than requiring the user to enter their private key directly.

This allows for added security as the private key is never exposed and the seed phrase can be stored in a safe place, also it is useful for cold storage use cases as it allows for offline signing of transactions. The signed transaction can then be broadcast to the network to be included in a block and processed. Some hardware wallets like Trezor and Ledger support this feature.
