The Public Mempool is a
Shark Tank.
Publicly broadcast trades can be visible to searchers. Where relay support applies, FRB routes transactions through Flashbots (EVM) and Jito (Solana) private relays to reduce public-mempool exposure before inclusion.
Public Mempool
- ❌ Visible to everyone
- ❌ Vulnerable to Sandwich Attacks
- ❌ Gas Wars & Failed Txs
FRB Private Relay
- ✅ Kept out of the public mempool where supported
- ✅ Designed to reduce sandwich exposure
- ✅ Simulated before bundle submission
Atomic Execution
Bundles target atomic execution, but inclusion and execution still depend on relay, builder, network, and transaction conditions.
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. Private Inclusion
Private inclusion reduces public-mempool front-running exposure; builder and execution risks remain.
Common Questions
Does this cost extra gas?
Private relay routing does not add a separate FRB gas charge. Network fees and any relay or builder requirements vary, so review the current route settings before submitting.
Which chains are supported?
Availability depends on the chain, selected provider, and current relay support. Check the route options in the Agent before submitting a live bundle.
