Senior Blockchain / CEX Development Team Required – AlphaNex Project Overview We are building AlphaNex, a new cryptocurrency trading platform backed by significant investment and a clear long-term vision. We are looking for an experienced technical partner, not simply developers who implement specifications. The selected team must be capable of reviewing our existing MVP, challenging architectural decisions, identifying risks, recommending what should be reused/refactored/rebuilt, and ultimately developing a secure, scalable, production-ready CEX. Our target is an initial production-ready release within approximately 3 months. We understand this is aggressive and expect an honest technical assessment based on the existing codebase, remaining scope, dependencies, and required team size. Security, scalability, reliability, performance, and engineering quality are critical. Existing AlphaNex MVP An MVP is already under development. GitHub Repository: https://github.com/AlphaNex-Lab/Exchange Read-only GitHub access will be provided to shortlisted teams. The first objective is a technical due-diligence review to determine: What has been built correctly What can realistically be reused What requires refactoring What should be rebuilt What must be developed from scratch Missing functionality Architectural and security issues Scalability limitations Requirements for production readiness Core Platform Scope The production platform is expected to include: 1. User & Account Management Registration/authentication, email/phone verification, 2FA, profiles, account status, portfolio/balance management, transaction history, audit logs, and RBAC. 2. Spot Trading Trading pairs, buy/sell, market and limit orders, cancellation/status, order/trade history, validation, balance reservation/locking, trading fees, trading limits, and minimum/maximum order sizes. 3. Matching Engine & Order Book Assess the existing implementation for architecture, order-book design, sequencing, matching logic, concurrency/race conditions, latency, market integrity, persistence/recovery, failure handling, and scalability. Clearly classify whether it should be reused, refactored, or rebuilt. 4. Internal Ledger & Accounting Double-entry ledger, available/locked balances, trading transactions, deposits/withdrawals, fees, internal transfers, reconciliation, idempotency, auditability, financial consistency, and error recovery. 5. Wallet & Custody Hot/cold wallet strategy, deposit addresses, blockchain monitoring, transaction broadcasting, confirmations, reconciliation, withdrawals, limits/risk controls, key management, private-key protection, and operational security. Production-grade wallet/custody experience is highly preferred. 6. Deposits & Withdrawals Address generation, blockchain monitoring, confirmation management, deposit crediting, withdrawal queues, manual/automated approvals, transaction signing, risk checks, failed transaction handling, reconciliation, and network-fee management. 7. Blockchain Infrastructure Node/API and RPC integrations, blockchain indexing, transaction/address monitoring, confirmation tracking, retry/failure handling, asset management, and multi-chain abstraction. The architecture should allow additional networks/assets to be added without major redevelopment. 8. Liquidity Integration External liquidity providers, market makers, aggregation, price feeds, order routing, market-data normalization, monitoring, failover, APIs, and liquidity risk management. 9. Real-Time Market Data Ticker data, order-book updates, trade streams, OHLC/candlesticks, market statistics, WebSockets, REST APIs, event streaming, and low-latency distribution. 10. APIs REST/WebSocket APIs for authentication, accounts, trading, orders, market data, wallets, deposits, and withdrawals, with appropriate security, rate limiting, scalability, versioning, monitoring, and documentation. 11. KYC / AML / Compliance Integration with suitable third-party providers for KYC/identity verification, AML and sanctions screening, transaction monitoring, risk scoring, account restrictions, compliance workflows, suspicious-activity flags, and audit trails. 12. Admin & Operations User/KYC management, account restrictions, asset and trading-pair management, wallet and transaction management, withdrawal approvals, fees, trading limits, risk controls, liquidity/system monitoring, audit logs, reporting, and administrator RBAC. 13. Security & Risk Review and recommend controls for authentication/2FA, RBAC, API security, wallet/custody, key management, withdrawal controls, fraud monitoring, rate limiting, account takeover prevention, secrets management, encryption, audit logging, infrastructure security, DDoS protection, monitoring/alerting, backups, disaster recovery, and incident response. 14. Infrastructure & DevOps Assess cloud architecture, containers, CI/CD, infrastructure-as-code, database architecture, caching, queues/event streaming, load balancing, horizontal scaling, monitoring/logging, high availability, failover, backup/recovery, staging/UAT, and production deployment. Technical Due-Diligence Deliverable Before committing to the full development contract, provide an assessment covering: Architecture: Current stack, services/components, database/API architecture, infrastructure, and third-party integrations. Code Quality: Structure, maintainability, technical debt, testing, documentation, dependencies, and scalability. For each major module, classify it as: REUSE – suitable with minimal changes REFACTOR – usable foundation but requires substantial changes REBUILD – should be replaced NEW DEVELOPMENT – functionality does not currently exist Also identify security vulnerabilities, architectural risks, production blockers, and everything required before launch. 3Month Timeline Assessment Our target is approximately 3 months for the initial production-ready release. We need an honest assessment of: Whether 3 months is realistically achievable Scope deliv
