Want to create your own 24 word Seed Phrase for your Bitcoin wallet? You can select the first 23 from the official list of 2048 words, but the 24th word must be calculated. This is what SeedPicker can help you with. You will also get the corresponding Extended Public Key, which will enable you to create multisig wallets without needing a hardware wallet (or together with hardware wallets)

Make sure your 23 words are generated in a random and secure fashion! Read the guide for how to accomplish this.

SeedPicker has been developed and tested to work well with Specter Desktop.

SeedPicker is 100% Open Source software. Requests or contributions are always welcome!
