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

type Error = SignError

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>
