Test in the Matrix.
Profit in Reality.
Don't burn real ETH testing a new strategy. FRB's Simulation Mode forks the mainnet state locally, letting you run thousands of transactions against real market conditions without spending a dime on gas.
Local Forking
We use a light version of Anvil under the hood to instantly create a local copy of the blockchain state. No remote RPC limits.
P&L Analysis
Get detailed execution reports breakdown: swap slippage, gas costs (L1 + L2), and net profit for every simulated trade.
Strategy Backtesting
Replay past opportunities. Provide a transaction hash of a missed arb, and see if your configuration would have captured it.
Simulation FAQ
Do I need real funds to simulate?
No. The simulator unlocks "impersonated accounts" locally, letting you pretend to have unlimited ETH to test capital efficiency.
Is the simulation 100% accurate?
It's 99.9% accurate for logic. However, it cannot predict "competitive" factors like other bots trying to land the same block 0.1ms faster than you.
