Stellar Transaction Visualizer is a professional-grade tool designed to help developers and users analyze, simulate, and debug Stellar blockchain transactions with clarity and ease. Built on modern web technologies, this visualizer transforms complex transaction data into intuitive, interactive experiences. At its core, the platform features a dynamic visual graph that displays each transaction's flow - complete with color-coded connections, animated sequencing, and detailed operation nodes showing type-specific data. Whether you’re tracking payments, contract interactions, or account creations, every element is rendered for quick understanding.

Products & Services

We are building a Stellar Transaction Visualizer and Debugger, a developer-focused tool that makes it easier to understand, simulate, and debug both Stellar Classic and Soroban smart contract transactions. Using Stellar SDK and the Soroban client, the platform offers interactive visualizations, smart contract call analysis, testnet simulations, and error diagnostics. By clearly displaying the flow and structure of transactions, the tool supports both new and advanced developers building on Stellar. Future plans include providing a lightweight SDK for seamless integration into existing wallets and explorers, increasing its accessibility and ecosystem impact. This directly supports Stellar’s goal of growing a strong, tool-rich smart contract development environment.

Our tool is not intended to compete with full-featured explorers like Stellar Expert, but rather to complement them by focusing specifically on transaction visualization, debugging, and Soroban smart contract introspection—features not currently offered in traditional explorers.

While Stellar Expert excels at displaying transaction data and account history, it does not provide a flow-based view or interactive debugging for Soroban contracts. Our tool bridges that gap by offering a developer-friendly visual layer that shows the sequence and relationships between operations, contract calls, and errors.

To avoid duplicating existing explorers, we plan to release an SDK that enables platforms like Stellar Expert, Freighter, or custom dApps to embed our visual flow component or debugging features within their own UI. This modular approach reduces friction and increases adoption, allowing users to access deeper transaction insights without leaving their preferred explorer.

Ultimately, the goal is to integrate rather than compete, making our tool a back-end service and front-end component that can serve the broader Stellar ecosystem and enhance the debugging experience across tools.

Success Criteria

Developers can visualize Stellar and Soroban transactions in a clear flow format.
SDK is adopted by at least one external explorer or wallet.
The tool successfully supports both testnet and mainnet transactions.

Go-To-Market Plan

Our primary audience includes developers building on Stellar and Soroban who need better tools for debugging and understanding transactions. The initial focus is to launch the tool for testnet transactions and gather developer feedback via Stellar community forums and Soroban channels. We will then release an SDK to enable integration into third-party explorers and wallets, increasing exposure. As the product matures, we aim to collaborate with existing tools like Stellar Expert for adoption

Traction Evidence

While still in the early stages, I've made significant progress:
A working MVP is functional on the testnet.
A public demo and GitHub repository is already published.
I will start exploratory conversations with teams in the ecosystem regarding SDK integration and feedback collection.
I'm committed to ongoing community engagement and transparent development.

*It's important to highlight that the tool has already been deployed as a fully functional MVP on testnet, allowing anyone to test it firsthand, a clear demonstration of both the project's feasibility and my technical capabilities.

Team

I'm a full-stack blockchain developer with over 5 years of experience in programming, I’ve led and contributed to multiple large-scale projects and created several developer tools. In 2025, I was awarded first place for my project "RealVerse", an innovative platform that specializes in tokenizing and managing RWAs.
