Private mempool on Avalanche C-Chain: protect swaps & pool creation
How transactions on Avalanche C-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.
Avalanche C-Chain for liquidity providers
Avalanche C-Chain is an EVM network with sub-second finality. BaniPool supports Uniswap v2, v3 and v4 pools for AVAX, stablecoins and Avalanche ecosystem tokens. Gas is paid in AVAX and is usually only a few cents.
The mempool on Avalanche C-Chain
Avalanche C-Chain has a public mempool; MEV activity is lower than on Ethereum or BSC but still present. There is no documented public private-RPC service for Avalanche yet, so BaniPool sends its 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 Avalanche C-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.
