Agent Simulation Environment with Forked Mainnet

[grantfox-oss]

Priority: High
Category: Simulator

Description

Enhance the current simulation environment to support forked mainnet testing, allowing users to test agents with real historical state from mainnet before deploying them in production.

Definition of Done

• Mainnet forking capability for major chains
• Time-scaled simulation (fast-forward blocks)
• Transaction replay from historical data
• Gas usage estimation in simulations
• Simulation result comparison with real outcomes

Acceptance Criteria

• Can fork Ethereum mainnet from any block height
• Simulate 1000 blocks in under 60 seconds
• All agent actions recorded during simulation
• Gas costs accurately calculated in simulation
• Compare simulation outcomes with historical real results
• Export simulation reports as JSON/PDF
• API endpoints to manage and execute simulations
