How It Works

Four steps, from quote to settled swap — on Solana.

1. Compare

Cloak requests quotes for your pair and amount from Solana aggregators — starting with Jupiter, which routes across the major Solana DEXs — and picks the best output. More aggregators are added over time, so "best price" is compared, not assumed.

2. Shield

Instead of sending your swap the default way, Cloak:

• submits it through MEV-protected transaction paths (such as Jito bundles) rather than broadcasting it broadly;
• avoids sending it while a validator publicly flagged for sandwiching is the scheduled leader — Solana's leader schedule is known in advance;
• sets slippage tight enough that a sandwich is unprofitable, while still letting a normal trade go through.

3. Review

Before you sign, you see:

1. The quoted price, route, and expected output
2. Slippage tolerance — automatic by default, or set your own
3. The protection fee that will apply (see Fee Policy)

After the swap lands, Cloak checks the transactions immediately before and after yours in the same block and shows a protection receipt: whether anyone traded around your swap, and your actual fill versus the quote.

4. Sign

You sign with your own Solana wallet (Phantom, Solflare, Backpack and other standard wallets). Cloak never custodies funds — the swap executes through the aggregator's own on-chain program.
