Trade SOL, BTC and ETH perps on Solana while your size, direction, entry and liquidation price stay locked in a box. The chain gets two wallets and a seal. Liquidation hunters get nothing to aim at.
Two wallets, a timestamp and a seal. That's the whole story.
That's enough for anyone to check that every box is fully funded and every payout adds up.
Only you and your maker hold the salt that opens the seal. Everyone else gets a hash that proves the numbers match.
Pick a size and a side. Three makers lock their margin and each send back a quote meant for your eyes only.
Take the best price in one click, or compare the offers and pick. Both margins drop into one box, and neither of you can pull money out alone.
Close whenever you like and it pays out at the index price. The maker can only close it by liquidating you, and has to prove the price crossed your line without saying where the line was.
The desk runs as a simulation. Quotes, opens and closes use the live index price and real Kraken candles, paid in 5,000 test dollars that are worth nothing. It's the same maths a live desk would run.
Every position gets a real seal. The desk hashes each position with SHA-256 and a salt that only your tab keeps. The seal is what the chain would see. The numbers never leave your browser.
Every trade is you and one maker. The most you can win is the maker's margin and the most you can lose is your own. The maker sees your box. Nobody else does.
The maths is open. Everything the desk does lives in hush.js, a small module you can import from this site and check line by line.
