can use await this.bitgo.encryptAsync() instead of this.bitgo.encrypt() for the webauthn entry. it handles both v1/v2 based on encryptionVersion

webauthnInfo ?? undefined is a noop, just use webauthnInf

nit: use MPCv2PartiesEnum.USER instead of 1

Good catch on using a named constant. wouldn't work here though — this is the non-MPCv2 ECDSA path which uses 1-based indexing (1 = user, 2 = backup, 3 = bitgo). Used ShareKeyPosition.USER (= 1) from ../../../tss/types instead, which is the correct named constant for this code path.

What changed: - Thread webauthnInfo through createMpc/createKeychains so hardware authenticator (PRF-derived) encryption can be stored alongside the standard encryptedPrv on user keychains - Use encryptAsync instead of encrypt for webauthnDevices entries so v2 encryption is applied consistently - Replace ad-hoc literal 1 with ShareKeyPosition.USER in ecdsa.ts webauthn guard - Remove AddKeychainOptions annotation that was inadvertently excluding prv from the type - Rename WebAuthn passphrase param type to WebauthnKeyEncryptionInfo, move canonical definition to iWallets.ts, consolidate duplicate AcceptShareWebauthnInfo, and re-export from iKeychains.ts Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
