Changelog

What shipped. When it shipped.
Why it matters.

A single source of truth for Asylia's product, security, and hardware releases. No filler entries - if it is here, it moved the product.

v0.5.1·

Apr 27, 2026

Ledger PSBT signing is live

Ledger Nano X and Nano S Plus now complete the same register-and-sign flow as Trezor, directly inside Asylia.

Ledger support is now complete for the hardware families Asylia ships today. Ledger Nano X and Nano S Plus can register wallet policies and co-sign wsh(sortedmulti) PSBTs directly from the wallet.

What shipped

  • In-wallet PSBT signing through the Ledger transport.
  • Policy-aware review before a signature is accepted.
  • The same signer progress model already used for Trezor sessions.

Why it matters

Trezor and Ledger are now both first-class signers in Asylia. A 2-of-3 vault can mix the two families without leaving the product, exporting PSBT files, or round-tripping through Ledger Live.

Trezor PSBT signing now ships end-to-end

Register a Trezor Safe 3, Model T, or Safe 5 and co-sign any wsh(sortedmulti) PSBT directly from the wallet.

End-to-end Trezor support is live. Any multisig vault with a Trezor key in its quorum can now be signed from inside Asylia — no external tool, no manual PSBT export and re-import.

What shipped

  • signProposalWithTrezor wired into PsbtSignerList.
  • Full round-trip for 2-of-3 and 3-of-5 policies.
  • Progress feedback per signer, with graceful recovery when a device locks.

What's next

  • Ledger PSBT signing (registration is already live). Shipped in v0.5.1.
  • Device-state caching so the "re-open app" step disappears for repeat sessions.
v0.4.2·

Apr 14, 2026

Ledger key registration

Connect a Ledger Nano X or Nano S Plus and pull its xpub into a new or existing multisig vault.

Ledger support lands in two passes. The first — xpub registration — is live today. Open the + Add key modal, pick Ledger, step through the connect wizard, and the xpub is ready to be placed in a vault's quorum.

What shipped

  • WebHID-based transport, no companion app required.
  • BIP-48 derivation out of the box (m/48'/0'/0'/2').
  • Descriptor-aware address verification against the device.

What's next

  • PSBT signing on Ledger, closing the loop so the same device can co-sign without hopping out to Ledger Live. Shipped in v0.5.1.

Full interop export: Sparrow, Caravan, Core, Asylia-native

Every vault now ships four export formats so the same policy works in every major multisig UI.

Interoperability is a feature, not a fallback. Every vault's settings pane now exposes four export formats side by side, generated from the same wsh(sortedmulti) descriptor so the output is always in lockstep.

Formats

  • Asylia JSON — portable backup format for re-importing into another Asylia workspace.
  • Caravan JSON — drop-in for Unchained's browser multisig UI.
  • Sparrow JSON — config import for the Sparrow desktop client.
  • Bitcoin Core descriptor — importdescriptors JSON payload for bitcoin-cli, with a descriptor checksum.

Public beta. The door is open.

Asylia opens to the public. Anyone can create a wsh(sortedmulti) vault, pair a Trezor, and sign real transactions today.

The Asylia workspace is open to the public.

The product is deliberately narrow: Bitcoin only, wsh(sortedmulti) only, Trezor signing at this milestone with Ledger signing next (now live in v0.5.1). The shape is going to stay narrow. We would rather ship one calm script that is reviewed, tested, and interoperable than a wide menu of policies with uneven implementations.

Thank you to everyone who tested Asylia through the private alpha. The feedback shaped the keys dashboard, the PSBT review step, and the calm chrome that now runs through every surface.

Audit scoping begins

First external review of btc-core and hardware transports is in planning with two Bitcoin-native audit firms.

The first external audit is now in the scoping phase. We are talking with two reputable Bitcoin-native audit firms about a btc-core + hardware-transport review as the first pass, covering descriptor parsing, PSBT construction, BIP-48 derivation, and the Trezor / Ledger transport glue.

When the audit lands, the full report and any findings will be published on this changelog unredacted, alongside the fix commits.

Until then, the MIT packages are open for community review:

  • @asylia/btc-core
  • @asylia/blockchain-data-btc
  • @asylia/hw-trezor
  • @asylia/hw-ledger
  • @asylia/shared-types
