Avail announced ShieldTX (@ShieldTXxyz) on Oct 28, 2026 as its enterprise privacy route into Hyperliquid for whales, desks and funds.

It claims public Hyperliquid wallets cost large traders on every trade, citing a screen of 332,317 wallets over 30 days with median 63 bps execution loss per trade across seven top perp traders from copy-trading, and says sub-accounts, wallet rotation and third-party tools still leave links via onchain traces, Arkham and visible PnL.

It claims to work by placing every trade from a brand-new Hyperliquid wallet with nothing linking trades onchain to the trader or to each other, while keeping a full history for audits and compliance, built on Avail's ZK privacy layer. Avail co-founder Anurag Arjun pitched it the same way here, and The Block covered it as exclusive here.

The critique, laid out here, says funds go to an Arbitrum vault, get a separate identity via Nightshade ZK infra, then a solver funds a position-specific Hyperliquid address, so it breaks the direct transfer chain but does not make the trade invisible.

That post argues the 63 bps figure is claimed, tied to 7 selected traders, not a verified average saving for all users, and that per Avail's Oct 7 architecture doc Hyperliquid positions stay publicly visible.

It adds the Nightshade sequencer can still see some order details, the solver knows which address was funded, and cross-chain verification currently relies on attestation rather than fully cryptographic proof.

So the claimed gain is unlinkability between main wallet and positions, not full invisibility, and readers should weigh who can still see what.
