Multi-device signing
FROST spreads signing power across devices, so one screen never becomes one point of failure.
Shared when needed.Private when it matters.
Threshold security for everyday use, with a post-quantum control path for recovery and high-risk wallet authority.

Everything in one place
Core features.One wallet.
Umbra privacy
Veil uses Umbra for shielded balances and private transfers without changing the wallet feel.
Future-proof control
WOTS+ authority is reserved for recovery, rekey, and irreversible control flows.
Solana-native surface
Extension-ready UX, familiar transaction flow, and a clean path into existing apps.

Threshold signing
Pick the quorum.
Vaulkyrie supports assisted fast signing and full multi-device threshold quorums. Change the mode and the signing geometry updates with it.
Private lane
Threshold custody stays separate.
Umbra gets its own local signer and its own recovery phrase, so the quiet rail can move without dragging the threshold path with it.
own signer / own recovery / quiet rail
Shielded pool
Balances can leave the public map.
Public SPL balances can be shielded into encrypted Umbra accounts, so the amount no longer sits in the open ATA view.

Private notes
Notes move. The inbox claims.
Receiver-claimable notes move through Umbra, then the inbox scans and claims them back into encrypted balance without exposing a straight path.

StrongholdPQC where

it fits.
Daily spend stays native. Stronghold only rises for recovery, rekey, and irreversible wallet authority.
FROST handles spend
SPENDRoutine transfers still leave as standard Ed25519 signatures on Solana.
Recovery opens the slower lane
WOTS+Stronghold only wakes when recovery or authority rotation needs the one-time path.
Next-key progression stays forward-only
XMSSEach high-risk action commits the next authority hash instead of reusing the same control key.
Pinocchio keeps only the state that matters
PINOOnchain state stays minimal while the deeper control lane moves off the routine spend path.
FAQCommon
Common
questions.
It is one wallet suite with three ways to hold: Shared, Veil, and Stronghold.
Yes. Vaulkyrie is built to feel familiar when you connect it to everyday Solana apps.
Because one lost device should not mean one lost wallet. Shared control keeps the hold spread out.
It is the deeper hold for funds that should stay put, a quantum-safe vault with WOTS+ admin authority reserved for recovery, rekey, and other high-risk control flows.
Wallet suite
Choose the mode that matches the risk.
Vaulkyrie is being built as a Solana wallet suite: shared-control vaults, post-quantum recovery paths, privacy-oriented transfer flows, and developer tools that can plug into existing products.
Browser Extension
Use Vaulkyrie from the browser wallet surface while the production extension moves toward review.
Coming SoonThreshold Vault
Split wallet control across devices and approve with threshold coordination instead of one hot key.
Dev PreviewPQC Wallet
Test Winternitz-style one-time authority flows for post-quantum recovery and admin paths.
ResearchPrivacy Vault
Route private-transfer workflows through the wallet suite while keeping the user experience familiar.
ExperimentalSDK and CLI
Integrate Vaulkyrie into developer workflows as the npm package and crates move toward release.
PreparingBuilt in the open
The wallet, docs, extension packaging, SDK, and CLI are moving toward public developer previews. Start with the documentation, then follow the organization for releases and package announcements.
