In a standard Ethereum swap, every detail: your wallet address, the amount swapped, the exact time, and the destination is publicly broadcasted on-chain for anyone to see. Ethereum's transparency, while a core strength, makes it one of the most surveilled blockchains: chain analysis firms, MEV bots, and wallet trackers can monitor your every move. For high-net-worth holders, DeFi power users, or anyone who values financial privacy, swapping ETH through a private layer is no longer optional. It's essential.
On a public DEX, anyone can track your ETH movements, see your wallet balance, and link your activity across protocols. Our private swap layer decouples your sending wallet from the destination, making it impossible to trace the on-chain connection between your source ETH and your received token.
Ethereum's public mempool is a hunting ground for bots. Standard ETH swaps are routinely targeted by sandwich attacks, bots detect your pending transaction, buy ahead of you to drive up the price, and sell immediately after. By routing through private RPC relays, your ETH swap never enters the public mempool, guaranteeing the rate you see is the rate you get.
Once you make a public Ethereum swap, your wallet address becomes a target. Data aggregators, airdrop farmers, and dusting attackers regularly monitor active ETH wallets. A private swap ensures your post-swap wallet remains clean and unlinked from your transaction history, invisible to third-party tracking services.




Ethereum (ETH) is the native currency of the Ethereum blockchain; the world's largest smart contract platform, home to DeFi, NFTs, DAOs, and thousands of dApps. ETH is used to pay for gas fees, participate in DeFi protocols, and store value across the Web3 ecosystem. It is held by everyone from retail investors to institutional funds, making on-chain privacy a serious concern: your ETH wallet is a window into your entire financial life on-chain.
