Functionality

  • Enable trust-minimized P2P swaps of shielded assets
  • Ensure atomicity (either both sides complete or neither does)
  • Support cross-chain swap capability
  • Provide trustless escrow without intermediary knowledge
  • Enable OTC trading for large deals

+ (Privacy, Anonymity, Censorship-Resistance)

  • Hide counterparties (neither party’s identity or address revealed)
  • Conceal amounts (trade sizes not publicly visible)
  • Protect asset types being swapped
  • Prevent timing analysis (swap negotiations and execution not linkable)

Demand Validation

Potential Users: Early adopters, OTC traders, cross-chain users, arbitrageurs

Use Cases:

  • Cross-chain swaps: Exchange assets between privacy L1 and other chains
  • OTC trading: Large trades without market impact or public visibility
  • P2P exchange: Direct user-to-user trading without DEX
  • Private arbitrage: Exploit price differences across venues privately
  • Trustless escrow: Buy/sell with strangers without intermediaries

Possible Implementation

  • Hash Time-Locked Contracts (HTLCs) with privacy: Traditional atomic swap mechanism enhanced with ZK proofs, shielded lock and unlock conditions
  • Adaptor signatures: Cryptographic technique for atomic swaps with no on-chain hash revelation required
  • ZK atomic swaps: Zero-knowledge proofs for swap conditions with fully encrypted swap parameters
  • Blind escrow: Third-party facilitator who cannot see trade details, trustless via cryptographic commitments

Technical Validation

Risks & Challenges:

  • Counterparty discovery: Finding trading partners without revealing intent
  • Price negotiation: Agreeing on rates privately
  • Cross-chain verification: Validating external chain state privately
  • Timeout handling: Managing refunds if swap fails
  • Fee coordination: Determining who pays gas on each chain

Integration Points:

  • Private communication channels for off-chain trade negotiation
  • Decentralized order books for publishing trade offers without revealing identity
  • Reputation systems via ZK reputation proofs
  • Bridge integration for cross-chain atomic swaps
  • DEX fallback if atomic swap fails
