TRC-20 Simulation System

TRC20 Simulator is a complete, production-oriented blockchain payment testing platform built for developers, agencies, fintech teams, and founders experimenting with TRON-based payment flows.

The platform provides a safe, testnet-only environment where users can connect a TronLink wallet, view test TRX and TRC-20 token balances, prepare and sign test-token transfers, and monitor transaction activity. Wallet private keys and recovery phrases never enter the application—transactions are signed directly inside TronLink.

Merchants can create payment requests containing an amount, description, and expiry time. Each request generates a unique checkout URL and QR code that customers can open to connect their wallet and complete a test payment through a polished, Stripe-inspired checkout experience.

A developer console allows users to register HTTPS webhook endpoints, generate simulated payment events, and inspect delivery logs. Supported events include `payment.created`, `payment.pending`, `payment.completed`, and `payment.failed`, with HMAC-SHA256 signatures available for testing webhook verification.

The administration dashboard provides tools for monitoring users, disabling accounts, searching transactions, reviewing API activity and request logs, and checking the configured TRON testnet connection.

The project uses a modern full-stack architecture:

- Next.js 16, React 19, TypeScript, Tailwind CSS, and React Query

- NestJS, TypeScript, Prisma ORM, and PostgreSQL

- TronWeb and TronLink wallet integration

- JWT authentication with HttpOnly cookies and bcrypt password hashing

- Docker and Docker Compose

- Deployment support for Vercel, Railway, AWS, and DigitalOcean

Security measures include input validation, CSRF and CORS protections, rate limiting, role-based authorization, encrypted webhook secrets, signed payment intents, secure error handling, and explicit Shasta/Nile network restrictions.

The package includes the complete frontend and backend source code, database migrations, environment templates, Docker configuration, deployment documentation, security documentation, marketplace graphics, technical due-diligence materials, and a buyer handoff guide.

This application is intended exclusively for development, demonstrations, education, and integration testing. It does not process real USDT, store wallet private keys, or support TRON mainnet by default. Test tokens have no monetary value.

TRON payment integrations are difficult to build and test safely without risking real funds or spending significant time creating wallet connectivity, transaction handling, checkout flows, webhooks, and administration from scratch.

TRC20 Simulator solves this by providing a ready-made, testnet-only environment where developers can connect TronLink, simulate TRC-20 payments, generate payment links and QR codes, monitor transactions, test webhook integrations, and manage users from one platform.

It reduces development time, avoids mainnet financial risk, and gives founders, agencies, and fintech teams a production-oriented foundation they can customize, white-label, and extend.
