Private mempool on BNB Smart Chain: protect swaps & pool creation
How transactions on BNB Smart Chain can be seen by bots before they land — and what BaniPool does to protect your swaps, Zaps and pool creation.
Sandwiches, front-running and snipers
Sandwich: a bot buys right before your swap (pushing the price up) and sells right after — you get the worst price your slippage allows. Sniper: a bot buys into a new pool before its creator finishes seeding it. Both require seeing your transaction before it lands.
How to turn it on
- Open ⚙ (slippage settings) in any BNB Smart Chain transaction dialog: Swap, Zap In, add liquidity or Create pool.
- In the "Private mempool (RPC)" section, press "Add to wallet" next to one of the available private RPCs.
- Approve it in your wallet. If the wallet rejects automatic setup (e.g. MetaMask for Ethereum Mainnet), copy the URL and add it manually: Settings → Networks → BNB Smart Chain → add RPC, and make it the default.
- From then on, swaps & deposits from your wallet on BNB Smart Chain go straight to builders instead of the public mempool. The BaniPool automation keeper already uses private RPCs with no setup.
BNB Smart Chain for liquidity providers
BNB Smart Chain (BSC) is an EVM network with sub-second blocks, cheap gas and a large retail user base. BaniPool supports Uniswap v2, v3 and v4 pools on BSC. Gas is paid in BNB and is usually just a few cents per transaction.
The mempool on BNB Smart Chain
BSC has a public mempool and very active MEV bots — sandwiches on small-cap swaps are common. On BaniPool, automation keeper transactions are sent through PancakeSwap MEV Guard (powered by 48 Club) and BlockRazor, straight to builders without public broadcast. For transactions from your own wallet, add those private RPCs to your wallet in one click from ⚙ in any transaction dialog.
Honest limits
A private mempool hides a transaction before it lands, not after: once confirmed, the transaction and pool are public on-chain. Block producers (validators / builders) still see it. Sensible slippage is still needed.

FAQ
Does BNB Smart Chain have a public mempool?
Is the transaction really hidden?
Hidden from the public until it lands. After that it is visible like any other transaction on the explorer — what is prevented is bots reacting before your transaction executes.
How much does it cost?
On Solana just a small Jito tip per transaction (capped at 0.0001–0.002 SOL). On Ethereum & BNB the private RPCs (Flashbots Protect, MEV Blocker, PancakeSwap MEV Guard, BlockRazor) are free — you only pay normal gas. BaniPool adds no fee for this feature.
