Wasabi Preview 1 — hardware wallet coinjoin

Wasabi Preview 1 — hardware wallet coinjoin

Unofficial preview build from the kravens fork, based on official v2.8.1, merging all hardware-wallet coinjoin work into one build for testing and feedback:

• Trezor (Model T, Safe 3, Safe 5) — SLIP-25 coinjoin account, on-device authorization. Most mature; mainnet-verified.
• Coldcard Mk4/Mk5 — requires our custom Coldcard firmware (branch feature/slip19-coinjoin, or feature/slip19-coinjoin-edge for the edge/taproot line) adding SLIP-19 ownership proofs and the coinjoin HSM rules. Prebuilt signed images (Mk4 5.6.0 and Edge 6.6.0X for Mk4/Mk5) are on the firmware release. HSM policy is approved on the device, then signing runs unattended under it. Tested on Windows/Linux/Mac.
• Foundation Passport Prime — see the Coinjoin Signer dev demo on Foundation's app showcase. Requires a custom KeyOS firmware build (stock is not compatible). Developer demo.
• Krux — requires the coinjoin signing extension on the device plus the kruxd companion daemon. Developer demo.

Also includes a fix for the v2.8.1 initial-sync slowdown (filter-serving peers no longer disconnected on block download timeout).

⚠️ Experimental software, not signed by the Wasabi team. Use small test amounts. Verify downloads against the attached SHA256SUMS.txt, signed by SHA256SUMS.txt.sig — PGP key fingerprint 2536 F69E 9C37 2566 2B6C 146B DCF1 7F7A 0127 2020 (Kevin Ravensberg). If the built-in updater offers you an update, that is the official build without hardware-wallet coinjoin — decline it to keep testing. See PREVIEW.md for per-device setup and how to report feedback.
