Learn before
you transact.
An interactive tutorial for building practical Bitcoin and self-custody knowledge—one short lesson at a time.
Sparrow turns unfamiliar wallet concepts into clear explanations, guided walkthroughs, and quick knowledge checks.
Start with the foundations, then go deeper.
Move from Bitcoin basics to transaction review, fees, UTXOs, hardware workflows, privacy, backups, and common mistakes. Each module is divided into short lessons that are easy to revisit.
Short lessons with useful practice.
- Plain-language explanations of technical ideas.
- Step-by-step walkthroughs that make each concept concrete.
- Knowledge checks that help you confirm what you understood.
- Bookmarks and private notes for your own questions and takeaways.
Practice careful thinking before real actions.
Explore how to review recipients, amounts, fees, change, confirmations, signing flows, backups, and privacy tradeoffs. The goal is not to rush you—it is to help you recognize what deserves a pause.
Progress that stays close.
Completion, bookmarks, and lesson notes are stored locally so you can pick up where you left off. Search the course, filter by topic, choose light or dark appearance, enlarge lesson text, and continue learning offline after the course has loaded once.
A tutorial, not a financial product.
Sparrow: Self-Custody is for education. It does not create an account, manage funds, connect to a financial service, or replace independent verification. The lessons use fictional practice examples and are not financial, legal, tax, or investment advice.
Useful whether you are starting out or reviewing your setup.
Use Sparrow to learn the vocabulary, prepare better questions, revisit a concept before a transaction, or build a personal checklist for safer self-custody.
