Overview
The Trading domain addresses execution privacy requirements for institutional trading workflows, including RFQ (request-for-quote) intent concealment, price/size confidentiality, and pre-trade leakage control.Key Focus: Protecting trade intentions before execution while ensuring atomic cross-domain settlements (DvP/PvP) without timing vulnerabilities.
Core Requirements
Pre-Trade Privacy
Conceal RFQ intent, size, and price information to prevent front-running and information leakage
Atomic Settlements
Guarantee simultaneous delivery-versus-payment without HTLC timing risks
Cross-Chain Atomicity
Enable DvP/PvP across different chains with strong cryptographic guarantees
Post-Trade Privacy
Maintain confidential balances and positions after trade execution
Technical Considerations
Pre-Trade Privacy Mechanisms
Pre-Trade Privacy Mechanisms
Shutter Network and SUAVE provide encrypted mempool solutions that hide trade intentions until execution. Consider latency trade-offs between threshold encryption and trusted execution environments.
HTLC Alternatives
HTLC Alternatives
Hash Time-Locked Contracts create brittleness in multi-party settlements. ERC-7573 cross-chain intents and zk-SPV provide stronger atomicity guarantees without timeout dependencies.
ZK Shielded Balance Privacy
ZK Shielded Balance Privacy
Zero-knowledge proofs enable private balance tracking without revealing holdings to counterparties or the public. Essential for institutional position confidentiality.
Cross-Chain Verification
Cross-Chain Verification
zk-SPV (simplified payment verification) allows cryptographic proof of settlement on one chain to trigger atomic execution on another, enabling trustless cross-chain DvP.
Primary Use Cases
Private DvP
Atomic delivery-versus-payment with full execution and balance privacy (documentation pending)
Related Use Cases
Private Bonds
Fixed-income trading with confidential holdings and settlement
