Koker: Cryptocurrency Wallet & Trading Platform

Koker is a secure and feature-rich cryptocurrency wallet and trading platform designed to provide users with a seamless digital asset management experience. The platform enables users to store, send, receive, trade, and stake cryptocurrencies while maintaining high security, regulatory compliance, and operational transparency.

The objective of Koker was to create a scalable crypto ecosystem that combines wallet management, exchange functionality, AML compliance, and advanced security controls into a single unified platform for both end users and administrators.

As cryptocurrency adoption continues to grow globally, users demand platforms that offer not only trading capabilities but also secure asset management, regulatory compliance, and a user-friendly experience.

Many existing solutions either focus solely on trading or provide limited wallet functionality. Businesses entering the crypto industry also face challenges related to KYC compliance, AML monitoring, risk management, and secure transaction processing.

Koker was developed to bridge these gaps by providing a comprehensive crypto financial platform that supports secure onboarding, multi-currency asset management, trading, staking, compliance monitoring, and administrative controls.

To address these challenges, a comprehensive crypto platform was designed and implemented with key operational modules:

1. User Authentication & Security

• User registration, KYC verification workflows, Two-Factor Authentication (2FA), and email notifications.
• Address whitelisting for withdrawals and comprehensive audit logs to prevent unauthorized access.

2. Wallet Infrastructure & Non-Custodial Support

• Centralized multi-currency wallet with automated deposit detection across major blockchain networks.
• Support for non-custodial wallets and a double-entry internal ledger for accurate transaction reconciliation.

3. Compliance & Risk Management

• Integrated AML screening for every transaction with an automated risk-scoring engine.
• Continuous transaction monitoring that generates immediate alerts for administrative review.

4. Spot Trading, Exchange & Staking

• Real-time spot order execution engine for buying and selling cryptocurrencies with live order books.
• Flexible staking plans with automatic reward distributions and earnings tracking.

5. Administrative Operations
