( Confidential Crossing )

Your size moves markets.
Your intent shouldn't.

A dark pool for tokenized real-world assets on Ethereum Sepolia. Match large orders inside a Trusted Execution Environment. Absolute cryptographic privacy until the exact moment of settlement.

Open DeskSee what the chain exposes
The Leak

Public chains expose your book.

Pre-trade intent

The market front-runs you.

Order terms are visible in the mempool before they fill. When you trade size, the market moves against your limit price before execution.

Post-trade attribution

Competitors map your limits.

Counterparty pairs are legible on-chain forever. Once you settle, any observer can reverse-engineer your execution strategy.

Flow patterns

Your positioning is signal.

Consistent buying or selling from a known entity becomes public signal. Your liquidity needs become ammunition for the broader market.

The same disclosure regime as a regulated crossing network: pre-trade opaque, post-trade transparent. Zerk hides intent, not outcome.

Architecture

From intent to settlement.

  1. ( 01 )

    Encrypt

    Order terms are encrypted client-side into completely opaque 32-byte hex handles.

  2. ( 02 )

    Submit

    The public blockchain stores handles, never values. The mempool sees only noise.

  3. ( 03 )

    Match

    A Trusted Execution Environment blindly decides whether crossed orders overlap.

  4. ( 04 )

    Settle

    Matched pairs settle atomically through an unmodified Seaport contract.

Differentiators

Built for trading desks.

1.

Perfect Price Secrecy

Your limit price is never revealed to the public or the matching engine, even on a fully executed order.

2.

Blind Matching

The matcher runs inside a secure enclave. It pairs compatible orders mathematically without ever seeing the underlying values.

3.

Standard Infrastructure

Settles natively on Seaport. No proprietary rails, no fragmented liquidity, no forked settlement protocols.

4.

Selective Disclosure

Absolute privacy from the market, with auditor-grade viewing keys. Unmask specific trades for regulators without compromising your edge.

Trade size without telling anyone.

Two desks, one encrypted book, settlement on infrastructure you already trust.
