@ -6,16 +6,30 @@ The connection to the signing devices is implemented in [another
repository](https://github.com/wizardsardine/async-hwi).
## Specter
## [Specter DIY](https://github.com/cryptoadvance/specter-diy)
[Specter DIY](https://github.com/cryptoadvance/specter-diy) version v1.5.0 and above is supported.
Version 1.5.0 and above of the firmware is supported for use in P2WSH descriptors.
## Ledger
Support for use in Taproot descriptors has been implemented but not yet released.
Minimum supported version of the Bitcoin application is 2.1.0 (the first version to have full
Miniscript descriptors support).
## [Ledger](https://github.com/LedgerHQ/app-bitcoin-new)
## BitBox02
The Bitcoin application is supported for use in P2WSH descriptors starting with version 2.1.0. It is
supported for use in Taproot descriptors starting with version 2.2.1.
[BitBox02](https://github.com/digitalbitbox/bitbox02-firmware) version 9.15.0 and above is
supported.
## [BitBox02](https://github.com/digitalbitbox/bitbox02-firmware)
Version 9.15.0 of the firmware is supported for use in P2WSH descriptors.
Support for use in Taproot descriptors is not yet available in the firmware.
## [Coldcard](https://github.com/Coldcard/firmware)
Support for use in both P2WSH and Taproot descriptors has only been released in Beta as of this
writing. It is only supported by the [Edge
firmware](https://github.com/Coldcard/firmware?tab=readme-ov-file#long-lived-branches).
As of this writing, Coldcard on Taproot will only be usable for descriptors which only use a single
key as their primary path. This is due to a discrepancy in how Coldcard derives [deterministically
unspendable Taproot internal
keys](https://delvingbitcoin.org/t/unspendable-keys-in-descriptors/304).
