Required Methods

fn sign_ecdsa( &self, message: Sighash, pk: LegacyPk, origin: Option<&KeyOrigin>, ) -> Option<Signature>

Create signature with a given key for inputs requiring ECDSA signatures (bare, pre-segwit and segwit v0).

fn sign_bip340_key_only( &self, message: TapSighash, pk: InternalPk, origin: Option<&KeyOrigin>, merkle_root: Option<TapNodeHash>, ) -> Option<Signature>

Create signature with a given internal key using Schnorr signatures with BIP-340 signing scheme (taproot).

fn sign_bip340_script_path( &self, message: TapSighash, pk: XOnlyPk, origin: Option<&KeyOrigin>, ) -> Option<Signature>

Create signature with a given script path and x-only public key using Schnorr signatures with BIP-340 signing scheme (taproot).

fn should_sign_script_path( &self, index: usize, merkle_path: &TapMerklePath, leaf: TapLeafHash, ) -> bool

Detect whether a given taproot script spending path should be signed for a given input index.

fn should_sign_key_path(&self, index: usize) -> bool

Detect whether taproot key spending path should be signed for a given input index.
