Problem
On Hyperliquid, every trader's size, entry price, and liquidation level are public and live to anyone with a wallet tracker. Bots hunt stops, copy-traders ride flows, and whales trade against positions, forcing traders to operate "in a glass house" where their every move is visible to the market.
Solution
Sirius Protocol provides a private execution layer on Solana that connects to Hyperliquid's order book while keeping all user positions hidden. Trades are submitted as Sirius flow—the market sees Sirius, never the individual trader—while fills, size, entry, and liquidation prices appear only on the user's own screen. Every batch of trades is proven with zero-knowledge proofs and settled on Solana, where anyone can verify the aggregate without seeing individual positions. The platform also offers private USDC-backed balances for transfers, holds, spot trading, and swaps, plus a trading API for programmatic access. Users maintain self-custody with a bonded exit path, and balances and nonces are readable only by the account owner.
Target Audience
Sirius Protocol serves active traders, professional funds, desks, and institutional capital allocators who need confidentiality for their trading strategies and positions. The platform also targets Web3 applications and AI agents seeking private, compliant settlement infrastructure for moving real value.
