Private mempool on Robinhood Chain: protect swaps & pool creation
How transactions on Robinhood 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.
Robinhood Chain for liquidity providers
Robinhood Chain is an L2 built on Arbitrum technology by Robinhood for tokenized assets. BaniPool is among the first to support Uniswap v2, v3 and v4 pools on it — with Zap In, pool creation and position history. Gas is paid in ETH and is very cheap. If your wallet has no ETH on Robinhood Chain yet, move some first with the BaniPool Bridge.
The mempool on Robinhood Chain
Like Arbitrum, Robinhood Chain uses a sequencer without a public mempool: transactions are processed in arrival order, so classic sandwiches are hard to pull off. An extra private mempool is not needed.
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 Robinhood 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.
