Virtual Mainnet Forks

Overview

Virtual Mainnet Forks are a groundbreaking infrastructure component within the OSCA Stack, designed to replicate the full environment of EVM-compatible blockchains in a secure, isolated, and manipulable test instance. This feature enables simulation, testing, and auditing of real blockchain transactions and contracts without interacting with the actual mainnet — a powerful approach for detecting vulnerabilities and validating logic before real deployment or investment.

Key Features

1. Blockchain Simulation at Mainnet Scale

  • Each fork mirrors the current state of the EVM mainnet (e.g., Ethereum, BNB Chain, etc.).

  • All tokens, balances, contracts, and interactions behave exactly as on-chain.

  • Forks are initialized with the latest block, ensuring maximum accuracy.

2. Isolated Testing Environment

  • All tests and simulations occur off-chain in a secure, private container.

  • No impact on actual assets, liquidity, or users.

  • Transactions are gasless and instant within the test environment.

3. Use Cases

  • Contract Auditing: Perform logic-based and security tests on any deployed smart contract.

  • Trading Simulation: Try out buy/sell scenarios before investing in a token.

  • Tax Analysis: Detect and validate hidden transaction fees or dynamic tax mechanisms.

  • Honeypot Detection: Determine if tokens prevent selling or apply malicious behaviors under specific conditions.

  • Protocol Validation: Run complex interactions involving multiple protocols, LPs, or token flows.

4. Integration with oscAI

  • Our oscAI engine automatically deploys Virtual Mainnet Forks when analyzing tokens.

  • Test matrices are generated to trigger all possible contract behaviors under varied conditions.

  • Automated and manual audits benefit from full on-chain emulation without risk.

5. Advanced Developer Access

  • APIs available for devs to deploy custom forks.

  • Inject custom accounts, simulate whale movements, liquidity shifts, or even chain events like MEV.

  • Supports all major EVM chains (Ethereum, BNB, Base, Polygon, etc.).

Benefits

  • Security: Spot scams, exploits, or unusual logic before they impact real users.

  • Confidence: Empower users and developers to interact with blockchain applications knowing the risks.

  • Scalability: Enables scalable auditing and simulation for thousands of contracts in parallel.

  • Innovation: Fosters safe experimentation, testing, and education in a real-world replicated environment.

Availability

The Virtual Mainnet Fork infrastructure is integrated directly into oscAI and available as part of the audit and simulation engine. It powers test-matrix audits, transaction simulations, and user safety tools across the OSCA Stack.

Access is provided via:

  • oscAI Telegram Bot

  • oscAI Web App

  • Developer API (coming soon)

Summary

Virtual Mainnet Forks are at the core of OSCA Stack’s mission to make on-chain interactions safer, smarter, and more transparent. This breakthrough technology creates a reliable and realistic sandbox environment that enhances contract validation, investor protection, and blockchain development workflows.
