Every input, every output, every byte — before you broadcast. Built for those who value financial self-sovereignty.
Browsers are inherently less safe than dedicated desktop applications — their wide capabilities mean a large attack surface. Sparrow runs natively on Linux, with a deliberately limited scope.
Sparrow doesn't try to fit your coins into an account model. It embraces Bitcoin's UTXO model. You see exactly which inputs and outputs were sent or received from an address, and you can trace the transaction graph as far back as the coinbase transaction.
Read the best practices guide →No bank can freeze it. No government can inflate it away. No company can decide your account violates their terms. Bitcoin belongs to whoever holds the keys.
But holding keys comes with responsibility. That's why the tools you use matter — they need to be transparent, auditable, and under your control. Sparrow is built exactly for that.
Sparrow doesn't collapse coins into a balance. It shows every unspent output with labels, history, addresses, inputs, and outputs.
When you send, address labels follow wherever they appear.
Import Coldcard, Ledger, Trezor, Jade, BitBox02, Passport, SeedSigner and more over USB or vendor file formats.
Animated UR QR signing means no USB, no length limits.
Sparrow connects to Bitcoin Core directly or via Fulcrum, ElectrumX, Electrs, EPS — all over SSL. Public servers are available for those starting out; the goal is to graduate to your own private setup.
Sparrow bundles Tor and routes all connections through it automatically — no Tor Browser or system-level setup required. Combined with coin control and BIP47 PayNyms, privacy is structural, not optional.
