...It provides a rich graphical interface that exposes Bitcoin’s underlying UTXO model rather than hiding it behind abstractions, helping users understand every input, output, and fee involved in transactions. Sparrow supports advanced workflows such as Partially Signed Bitcoin Transactions (PSBT), multisignature setups, customizable fee selection, and comprehensive coin control — making it suitable for power users, privacy advocates, and those running their own full nodes. It integrates with a wide range of hardware wallets (e.g., Ledger, Trezor, Coldcard) and connects to Bitcoin Core or Electrum servers, including via Tor for enhanced anonymity.

...The AirGap Wallet is installed on your everyday smartphone. AirGap Vault is responsible for secure key generation. Entropy from audio, video, touch and accelerometer are used together with the output of the hardware random number generator. The generated secret is saved in the secure enclave of the device, only accessible by biometric authentication. Accounts for multiple protocols can be created. Transactions are prepared by the AirGap Wallet and then transferred to the offline device via QR code, where it is signed and sent back to the Wallet using another QR code. ...

...Coinjoin is a mechanism by which multiple participants combine their coins (or UTXOs, to be more precise) into one large transaction with multiple inputs and multiple outputs. An observer cannot determine which output belongs to which input, and neither can the participants themselves. This makes it difficult for outside parties to trace where a particular coin originated from and where it was sent to (as opposed to regular bitcoin transactions, where there is usually one sender and one receiver). Coinjoin can be applied multiple times, and as many transactions are grouped together, participants may save on transaction fees. ...
