dashcore-lib/lib/crypto/ecdsa.js

Lines 225 to 228 in c3c3fe5

	ECDSA.prototype._findSignature = function (d, e) {
	var N = Point.getN();
	var G = Point.getG();
	// try different values of k until r, s are valid

There's no good reason to reimplement ECDSA signing in JavaScript when @noble/curves exists.

There's also definitely no need to be using the unmaintained elliptic package for its Point class.
