Demo ID: preimage Status: Complete Demo Last Updated: September 30, 2025
Executive Summary
Problem Statement
BSV blockchain developers, particularly those working with sCrypt smart contracts, frequently encounter complex debugging challenges when working with transaction preimages and script code. Understanding the internal structure of transaction signatures, preimage components, and script assembly is critical for troubleshooting checkSig and checkPreimage exceptions, but current tools lack specialized interfaces for this analysis.
Solution Overview
Preimage is an early-stage web application designed to parse and visualize BSV transaction preimages. Built using modern web technologies through the Lovable development platform, it aims to help developers inspect preimage components and understand BSV transaction signature mechanisms.
Key Benefits
Advanced Debugging: Deep inspection of transaction preimage components for sCrypt development
Script Analysis: Convert complex script code to readable Assembly format
Signature Troubleshooting: Identify discrepancies in checkSig and checkPreimage operations
Educational Resource: Learn BSV transaction internals and signature mechanisms
Developer Productivity: Reduce debugging time for complex smart contract issues
Business Impact
