Just curious, this PR is intended to replace the sCrypt-Inc/bsv dependency with the bitcoin-sv/ts-sdk dependency, correct? Is it still on going?

Copilot

Pull Request Overview

This PR refactors the codebase to use a new TypeScript SDK abstraction layer instead of directly using the bsv library. The main purpose is to introduce a chain abstraction through a factory pattern that enables support for multiple blockchain implementations while maintaining compatibility with existing code.

Introduces a new Chain factory pattern with BSV implementation
Removes direct bsv library dependencies and replaces with abstracted interfaces
Updates test files to use the new SDK patterns and transaction handling
Migrates utility functions to use the new chain abstraction layer

This test file appears to be a temporary development/debugging file with console.log statements and incomplete test structure. Consider removing this file or converting it into proper unit tests with assertions.

Suggested change

console.log(key.toAddress())

import * as assert from "assert";

describe("Chain Factory and Script Tests", function () {

it("should create and manipulate LockingScript correctly", function () {

const factory = Chain.getFactory();

const s = factory.LockingScript.fromHex('76a914212771cc264264057238cc3b98a03ddd9aa3a31c88ac');

test/counter.test.ts

+
+        console.log('result', result)
+
+        let callTx = new Transaction()


The variable callTx is declared but Transaction is not imported. This will cause a runtime error since Transaction is undefined in this scope.

-      }));
+
+      const abn = unpack(this.flattenSha256(a[0], keyType));
+      const bbn = unpack(this.flattenSha256(b[0], keyType));


Accessing a[0] in this context appears incorrect. The variable a is the first element of a map entry, so it should be a instead of a[0]. This pattern is repeated on multiple lines.

Suggested change

const bbn = unpack(this.flattenSha256(b[0], keyType));

const abn = unpack(this.flattenSha256(a, keyType));

const bbn = unpack(this.flattenSha256(b, keyType));

+
+      const abn = unpack(this.flattenSha256(a[0], keyType));
+      const bbn = unpack(this.flattenSha256(b[0], keyType));


Same issue as above - accessing a[0] when a is already the key element. Should be a instead of a[0].

Suggested change

const bbn = unpack(this.flattenSha256(b[0], keyType));

const abn = unpack(this.flattenSha256(a, keyType));

const bbn = unpack(this.flattenSha256(b, keyType));

 export function pack(n: bigint): Bytes {
-  const num = new bsv.crypto.BN(n);
-  return num.toSM({ endian: 'little' }).toString('hex');
+  return num2bin(n);


The function calls num2bin(n) but num2bin is not imported or defined in this scope. This will cause a runtime error.

 export function unpack(a: Bytes): bigint {
-  return BigInt(bin2num(a));
+  return bin2num(a);


The function calls bin2num(a) but bin2num is not imported or defined in this scope. This will cause a runtime error.

Suggested change

return bin2num(a);

return bin2num(toHex(a));
