- Dispute, evidence and appeal workflows with arbitration
- KYC, reputation, fraud monitoring and admin dashboard
What is a P2P exchange?
A P2P exchange is a marketplace where buyers and sellers trade cryptocurrency directly with each other using their chosen payment methods, while the platform holds the crypto side in escrow, enforces trade rules and resolves disputes. Unlike an order-book exchange, the platform never takes the other side of a trade.
BitAzure builds P2P exchange platforms for regional operators, remittance businesses and exchanges adding a P2P channel. The platform comprises the marketplace service for offers and orders, an escrow layer implemented with a custodial hot wallet or smart contract, a dispute and arbitration service with evidence upload, KYC and fraud engines, a reputation system and the admin dashboard that operates it.
Trust is engineered through process: escrow locks funds before payment is confirmed, timers and evidence requirements govern each trade state, and appeals follow a defined workflow so outcomes are consistent and explainable.

Reference P2P exchange architecture
Web and mobile clients talk to a marketplace service that runs the trade state machine and consults the payment method registry. Escrow locks crypto for each trade, KYC and fraud engines gate participation, and a dispute service with evidence from chat decides outcomes that escrow enforces. The admin dashboard oversees all of it.
Hover or focus a component to see its role in the architecture.
- Web App (Offers · trades · chat): Trader interface for browsing offers, running trades and messaging counterparties.
- Mobile App (React Native): Shares business logic with the web app; push notifications for trade events.
- Marketplace Service (Offers · orders · timers): Offer management, order matching and the trade state machine with payment and release timers.
- Payment Method Registry (Per-country config): Configured payment methods, verification requirements and limits per market.
- Chat & Evidence (Messages · uploads): In-trade messaging and evidence upload with hashing, timestamps and retention.
- Escrow (Hot wallet or contract): Locks crypto at trade start and releases, refunds or splits according to trade state or dispute outcome.
- KYC & Fraud Engines (Identity · risk scoring): Identity verification, sanctions screening and real-time risk scoring of users and trades.
- Dispute & Arbitration (Queues · appeals): Case queues, arbitrator assignment, decisions and second-level appeals.
- Admin Dashboard (Ops · compliance · finance): Trade, dispute, user and escrow oversight with role-based access and audit logs.
- Blockchains (Settlement · sweeps): On-chain deposits, releases and cold-storage sweeps across supported networks.

Security practices in P2P exchange engineering
Escrow custody
Hot-wallet limits, cold sweeping and multisig approvals for large releases.
Account security
Two-factor authentication, device binding and withdrawal address allow-lists.
Evidence integrity
Uploads are hashed, timestamped and access-controlled for dispute review.
Fraud controls
Real-time risk scoring with holds, limits and manual review queues.
Data protection
KYC documents encrypted at rest with restricted access and retention policies.
Operational audit
All admin actions on trades, escrow and users are logged and reviewable.
We coordinate independent third-party audits on request and never claim an audit, certification or compliance status unless it has actually been obtained.
What to decide before launching a P2P exchange
Custody and licensing
Holding escrow funds usually requires licensing; contract-based escrow changes but does not remove obligations.
Payment method risk
Reversible methods such as cards and some bank transfers carry chargeback risk that pricing and limits must reflect.
Dispute policy
Clear rules for evidence, timers and outcomes reduce arbitration load and user complaints.
Merchant onboarding
Verified merchants provide liquidity but need limits, monitoring and fee structures.
Localisation
Currencies, languages, payment references and support hours differ by market.
Fraud evolution
Scam patterns change quickly; monitoring rules and reputation weights need ongoing tuning.
P2P Exchange questions
Crypto from the seller is locked when a trade starts. Once the buyer pays by the agreed method and the seller confirms receipt, escrow releases the crypto. If either party disputes, the arbitration process decides the outcome.
