Zashi x Keystone Hardware Wallet Integration
This integration marks a significant evolution in Zcash usability by enabling cold storage of shielded ZEC. The Zcash community has faced setbacks with other hardware wallet platforms in the past, but Keystone emerged as a collaborative partner willing to push boundaries and innovate alongside the Electric Coin Company. The Keystone team received a ZCG grant to fuel their side of the work.
