@BlockstreamJade hardware wallets are unaffected by the COLDCARD RNG vulnerability. Jade derives entropy from multiple independent sources (the companion app, user input, battery state, and more) as well as the chip's hardware RNG, which draws on Bluetooth radio noise.
If you're running the "No-Radio" firmware, Jade already compensates by design, seeding from internal chip noise on every boot and continuously mixing in sensor data.
The engineering behind Jade's RNG is solid.
