Sandwich bots on Solana feed on swaps sent with loose slippage to the wrong validator. Cloak compares prices across Solana aggregators, sends your trade through MEV-protected paths, and shows you after every swap whether anyone got in front of it — for a small fee, only when protection actually ran.
No protected path used, no fee — ever.
Your wallet signs every transaction.
See whether your swap was sandwiched — checked on-chain.
Hold $CLOAK to discount the protection fee.
Solana has no public mempool — transactions go straight to the validators scheduled to produce the next blocks. Whoever sees your swap first can trade around it.
A bot buys right before you and sells right after, pushing your price to the edge of your slippage tolerance. The wider the tolerance, the bigger the bite.
The loss shows up as a worse fill, not a line item — most swappers never know how much was extracted.
The flow Cloak is being built around on Solana — not live yet. See the roadmap for what ships when.
Cloak checks quotes from Solana aggregators — starting with Jupiter — and picks the best price.
Your swap is sent through MEV-protected paths with tight slippage, avoiding validators known for sandwiching.
Before you sign: price, slippage, and the exact protection fee. After it lands: an on-chain check of whether anyone traded around it.
You sign with your own Solana wallet. Cloak never custodies your funds.
Cloak charges a protection fee only on swaps that actually route through the protected path. If that path isn't available and your swap falls back to standard routing, you pay nothing extra.
| Standard swap | Protected swap | |
|---|---|---|
| Base swap fee | 0% | 0% |
| Protection fee | — | 0.15%–0.30%* |
| If protection isn't delivered | — | 0% |
*Draft rate — final figure to be confirmed before the Solana beta launches. No fee is charged today.
Cloak never holds your funds. Your wallet signs every transaction.
Swaps execute through the aggregators' own on-chain programs. Cloak's code is unaudited — only swap what you can afford to expose to that risk.
Protected sending reduces sandwich exposure — it does not eliminate every form of MEV.
