Class MnemonicIdentity

Readonlydescriptor

compressedPublicKey

• compressedPublicKey(): Promise<Uint8Array<ArrayBufferLike>>

  Returns the compressed public key for this identity.

  Returns Promise<Uint8Array<ArrayBufferLike>>

sign

• sign(tx: Transaction, inputIndexes?: number[]): Promise<Transaction>

  Sign the provided transaction inputs.

  Parameters

  • tx: Transaction

    Transaction to sign

  • OptionalinputIndexes: number[]

    Optional input indexes to sign. When omitted, the implementation should sign every signable input.

  Returns Promise<Transaction>

signerSession

• signerSession(): SignerSession

  Returns a signer session used for musig2 tree signing flows.

  Returns SignerSession

signMessage

• signMessage(
      message: Uint8Array,
      signatureType?: "schnorr" | "ecdsa",
  ): Promise<Uint8Array<ArrayBufferLike>>

  Sign an arbitrary message using the requested signature type.

  Parameters

  • message: Uint8Array
  • signatureType: "schnorr" | "ecdsa" = "schnorr"

  Returns Promise<Uint8Array<ArrayBufferLike>>

toReadonly

• toReadonly(): Promise<ReadonlyDescriptorIdentity>

  Converts to a watch-only identity that cannot sign.

  Returns Promise<ReadonlyDescriptorIdentity>

xOnlyPublicKey

• xOnlyPublicKey(): Promise<Uint8Array<ArrayBufferLike>>

  Returns the x-only public key used by Taproot scripts.

  Returns Promise<Uint8Array<ArrayBufferLike>>

StaticfromSeed

• fromSeed(seed: Uint8Array, opts?: SeedIdentityOptions): SeedIdentity

  Creates a SeedIdentity from a raw 64-byte seed.

  Pass { isMainnet } for default BIP86 derivation, or { descriptor } for a custom derivation path.

  Parameters

  • seed: Uint8Array

    64-byte seed (typically from mnemonicToSeedSync)

  • opts: SeedIdentityOptions = {}

    Network selection or custom descriptor.

  Returns SeedIdentity
