Blockstream Launches Jade Core to Simplify Bitcoin Self-Custody Without Sacrificing Security

Blockstream launched Jade Core on April 28, 2026 — a simplified, open‑source hardware wallet aimed at broadening Bitcoin self‑custody by combining guided onboarding, Bluetooth pairing and tight mobile/desktop integration while keeping private keys offline. The device emphasizes security (open‑source hardware/firmware, Blind Oracle PIN, device authenticity checks and clearer transaction displays) to reduce reliance on custodial platforms and supply‑chain risks. By lowering usability barriers, Jade Core may accelerate retail adoption of self‑custody solutions and reinforce demand for on‑chain Bitcoin ownership, a modestly bullish development for BTC market structure and long‑term adoption. Blockstream positions the product as part of a larger ecosystem linking retail tools with institutional rails, which could further support broader Bitcoin adoption.
