Struct SdkLwkSigner 

pub struct SdkLwkSigner { /* private fields */ }

A software signer

Implementations

impl SdkLwkSigner

pub fn new(sdk_signer: Arc<Box<dyn Signer>>) -> Result<Self, NewError>

Creates a new software signer from the given mnemonic.

Takes also a flag if the network is mainnet so that generated extended keys are in the correct form xpub/tpub (there is no need to discriminate between regtest and testnet)

pub fn fingerprint(&self) -> Result<Fingerprint, SignError>

Trait Implementations

impl Signer for SdkLwkSigner

fn sign_message( &self, _message: &str, _path: &DerivationPath, ) -> Result<MessageSignature, Self::Error>

Message signing is not used by the SDK (LWK only invokes this for its own AMP0 software/hardware signers, which the SDK does not use) and the SDK’s Signer abstraction does not expose a recoverable-sign-at-path primitive, so this is intentionally unsupported.

type Error = SignError

The user defined error type returned by the signer.

fn sign( &self, pset: &mut PartiallySignedTransaction, ) -> Result<u32, Self::Error>

Try to sign the given pset, mutating it in place. returns how many signatures were added or overwritten

fn slip77_master_blinding_key(&self) -> Result<MasterBlindingKey, Self::Error>

Return the slip77 master blinding key

fn derive_xpub(&self, path: &DerivationPath) -> Result<Xpub, Self::Error>

Derive an xpub from the master, path can contains hardened derivations

fn xpub(&self) -> Result<Xpub, Self::Error>

Return the master xpub of the signer

fn identifier(&self) -> Result<XKeyIdentifier, Self::Error>

Return the full identifier of the signer

fn fingerprint(&self) -> Result<Fingerprint, Self::Error>

Return the fingerprint of the signer (4 bytes)

fn keyorigin_xpub( &self, bip: Bip, is_mainnet: bool, ) -> Result<String, Self::Error>

Return keyorigin and xpub, like “[73c5da0a/84h/1h/0h]tpub…”

fn is_mainnet(&self) -> Result<bool, Self::Error>

Return true if the signer is for mainnet.

fn wpkh_slip77_descriptor(&self) -> Result<String, String>

Return the Witness Public Key Hash, slip77, descriptor for this signer
