Static Methods

calculateTweek(ProjectiveECCPoint pubPoint, {List? script}) → List<int>

_calculateTweek computes and returns the TapTweak value based on the ECPublic key and an optional script. It uses the key's x-coordinate and the Merkle root of the script (if provided) to calculate the tweak.

hashTapTweak(ProjectiveECCPoint pubPoint) → List<int>

Compute the TapTweak hash for a P2TR address.

liftX(ProjectiveECCPoint pubKeyPoint) → ProjectiveECCPoint

Lift the x-coordinate of a public key for P2TR.

taggedHash(dynamic tag, List<int> dataBytes) → List<int>

Compute a tagged hash for P2TR operations.

tweakPublicKey(ProjectiveECCPoint pubPoint, {List? script}) → ProjectiveECCPoint
