— Specter Wallet is a Bitcoin desktop wallet that connects directly to your own Bitcoin Core node, offering superior user experience and privacy compared to Electrum's reliance on remote servers.

— The Specter DIY hardware wallet uses off-the-shelf components (developer board, QR code scanner, optional secure element card reader) to reduce supply chain risk compared to dedicated hardware manufacturers.

— PSBTs (Partially Signed Bitcoin Transactions) and QR codes enable air-gapped communication between coordinators and signing devices, with animated QR codes able to handle large transaction data.

— Trezor One is outdated and problematic for Specter use due to passphrase vulnerabilities and inability to display passphrases on device; newer hardware wallets handle these issues better.

— Future roadmap includes bundling Bitcoin Core directly into Specter with a setup wizard defaulting to pruned nodes, reducing initial setup friction from 20+ steps to near-instant deployment.

— Multi-sig wallets become more practical and private as adoption increases and Taproot enables more flexible signing policies without on-chain visibility penalties.

— Run a pruned node locally with Specter on your laptop or home computer to achieve full node verification without requiring significant storage; this is now feasible for most users and far more private than light clients.

— Use hardware wallet diversity in multi-sig setups (e.g., mixing Coldcard with Specter DIY) to avoid single points of failure and gain flexibility combining QR codes and SD card transport methods.

— Defer Lightning adoption for now; Lightning infrastructure is promising but not yet urgent given current low on-chain fees; focus instead on custody, privacy, and self-sovereignty through tools like Specter.
