How your funds are protected on-chain.
Your trades, identity and PnL stay hidden from copy-traders and competitors. Funds move only when you sign for them.
Overview
Your USDC sits in an on-chain vault and moves only when you sign a transaction. Here's exactly what happens at each stage.
Token flow
-
1
Deposit
Your funds → Vault contract → ShieldTX
Your USDC lands in ShieldTX's on-chain vault on Arbitrum. The vault contract locks it and credits your ShieldTX account with a private balance only you can see.
- Your USDC stays locked in the on-chain vault on Arbitrum and is released only when you submit a signed transaction.

Open position
ShieldTX → Fresh Hyperliquid account
You choose a pair, direction, size, and leverage via the ShieldTX app. ShieldTX creates a brand-new Hyperliquid wallet per trade, on-chain, completely unlinkable to your deposit wallet or any previous on-chain trades. Your trade gets placed on Hyperliquid from this fresh wallet.
- You open and close the position from the ShieldTX app.
- Your order fills on Hyperliquid's order book, at the same price you'd get trading directly on HL minus the shielding fee.
- If opening the position fails for any reason, your full amount returns to your ShieldTX balance on its own.

Close position
Hyperliquid account → ShieldTX
Your position closes directly on Hyperliquid. Proceeds return to your ShieldTX balance, unlinkable to the Hyperliquid account used for the trade.
- Your position follows Hyperliquid's rules. It closes when you close it, or when a take-profit, stop-loss, or liquidation triggers. ShieldTX adds no rules of its own.
- ShieldTX validates that the settlement has completed on-chain before crediting your ShieldTX balance.

Withdraw
ShieldTX → Your wallet
Funds that aren't in an active trade can be withdrawn at any time. You sign a withdrawal request, and ShieldTX sends the funds to the address you choose once the withdrawal is confirmed on-chain.
- Funds move only when you sign a withdrawal request, and are sent to the address you choose.
- ShieldTX sends the funds once the withdrawal is confirmed on-chain.
