Private mempool on Arc: protect swaps & pool creation
How transactions on Arc 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.
Arc for liquidity providers
Arc is Circle's EVM network designed for stablecoins: gas is paid in USDC and finality is deterministic and sub-second. BaniPool supports Uniswap v2, v3 and v4 pools on Arc. Gas is paid in USDC (not ETH), so transaction costs are easy to estimate in dollars.
The mempool on Arc
Arc is run by a limited validator set with instant finality; there is no public private-mempool service for Arc today, so BaniPool sends Arc transactions normally — keep slippage tight.
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 Arc 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.
