The Public Mempool is a
Shark Tank.
Every trade you broadcast publicly is visible to predatory bots. FRB routes your transactions through Flashbots (EVM) and Jito (Solana) Private Relays, making them invisible until they are mined.
Public Mempool
- ❌ Visible to everyone
- ❌ Vulnerable to Sandwich Attacks
- ❌ Gas Wars & Failed Txs
FRB Private Relay
- ✅ Invisible until mined
- ✅ 100% Anti-Sandwich Protection
- ✅ No Gas paid if Tx fails
Atomic Execution
Your transaction is bundled with the miner's block directly. It either succeeds exactly as planned, or it doesn't happen at all.
1. Sign & Seal
You sign the transaction locally. FRB encrypts it before it leaves your machine.
2. Private Route
The bundle bypasses the P2P network and goes directly to benign builders (Flashbots, Jito, Beaver, Titan).
3. Mined Securely
It appears on-chain at the top of the block. No front-running possible.
Common Questions
Does this cost extra gas?
No. You typically pay the same base fee + a "tip" (priority fee) to the miner. In fact, you save money because you never pay for failed transactions.
Which chains are supported?
We support Flashbots on Ethereum Mainnet, Jito Block Engine on Solana, and similar private relays on BNB Chain (MevProtcol), Polygon (FastLane), and Base.
