Stop Bleeding to Sandwich Bots.
Extract Institutional-Grade MEV.
The mempool is a dark forest. FRB is your night vision. Execute private arbitrage bundles on Ethereum, Base, and Arbitrum. 100% sandwich-resistant. Zero failed transaction fees. Total local key control.
Invisible to the Mempool
Bypass the public mempool entirely. Our agent routes your transactions directly to trusted block builders via the Flashbots relay.
- Zero Reverts: You only pay gas if your bundle lands successfully.
- Anti-Sandwich: Predators cannot see or front-run your pending transactions.
Multi-Chain Dominance
Don't limit yourself to Ethereum L1. Deploy our lightweight agent on high-throughput L2s where arbitrage opportunities are frequent and gas is cheap.

"I switched from a custom Python bot to FRB. The Flashbots integration is faster than my own node."
"The multi-chain support is a game changer. I'm running stratgies on Base and Arbitrum simultaneously."
"Finally, a bot that keeps keys local. I wouldn't touch this if it required a cloud private key."
