Platform Architecture

A peer-to-peer exchange network enabling direct cryptocurrency/fiat transactions without intermediaries. Participants engage in atomic swaps where:

  • XMR serves as primary settlement currency
  • All trades secured through cryptographic deposits
  • Dispute resolution handled by independent arbitrators

Multisignature Security Implementation

Core Mechanism

Transactions utilize Monero's 2-of-3 multisignature protocol:

  • Three cryptographic keys generated per transaction
  • Two signatures required for fund release
  • Key distribution:
    • Trading counterparty A
    • Trading counterparty B
    • Designated arbitrator

Operational Workflow

  1. Deposit Locking

    • Both participants lock XMR deposits in multisig escrow
    • 20-minute blockchain confirmation period

  2. Trade Execution

    • Payment coordination occurs externally (bank transfers, crypto networks)
    • Platform tracks fulfillment through user confirmation:
      • Payment initiator: "Funds Sent"
      • Payment recipient: "Funds Received"

  3. Settlement

    • Successful verification triggers automatic escrow release:
      • Traded XMR to buyer
      • Security deposits returned (minus platform fees)

Participant Roles

Role Responsibilities
Offer Creator Lists exchange terms
Locks XMR collateral
Offer Acceptor Accepts published terms
Matches collateral deposit
Arbitrator Neutral dispute resolver
Holds emergency signing key

Transaction Lifecycle

  1. Offer Creation & Funding (Creator)
  2. Offer Acceptance & Funding (Acceptor)
  3. Multisig Escrow Establishment
  4. External Payment Execution
  5. Mutual Confirmation Protocol
  6. Automated Settlement or Arbitration

Critical Features

  • Non-Custodial Design
    Users retain wallet control throughout transactions

  • Collateral System

    • Mandatory security deposits from both parties
    • Forfeiture conditions: Protocol violations

  • Contingency Protocol
    Arbitration activation requires:

    • Mutual consent escalation
    • Evidence submission
    • Cryptographic proof verification

Operational Notes

  • Transaction Finalization
    Typical completion within 40 minutes (dual blockchain confirmations)

  • External Payment Risks
    Platform monitors but doesn't control external payment channels

  • Fee Structure
    Service charges deducted from returned deposits

This architecture enables trustless trading through cryptographic guarantees and economic incentives, maintaining user sovereignty while preventing malicious behavior.
