In this episode of BTC Sessions, Ben delves into the advanced features of Sparrow Wallet, a desktop Bitcoin wallet geared towards power users. The tutorial covers a range of topics, including signing and verifying messages to prove ownership of Bitcoin addresses, verifying software downloads using digital signatures, and sending Bitcoin to multiple recipients through manual and automated methods. Ben also discusses UTXO management for privacy, fee targeting strategies, sweeping private keys from paper wallets, utilizing NFC-enabled devices like TapSigner, and using testnets for risk-free experimentation. Additional features covered are PayNyms for creating static payment addresses without revealing personal information, understanding the settings screen and derivation paths, using border wallets for secure cross-border travel, exporting wallets for compatibility with other platforms, and bumping transaction fees for faster confirmation.
