What you get with this Offer
I will build a cryptocurrency exchange integration for your application — connecting to a centralised exchange (Binance, Coinbase Advanced, Kraken, or OKX) via their REST and WebSocket APIs, or to a decentralised exchange (Uniswap v3, PancakeSwap, or 1inch) via their SDK or smart contract interfaces — implementing market data streaming, order placement and management, balance checking, trade history, and webhook event handling for your specific trading or portfolio use case. Exchange API integrations that seem simple in documentation consistently reveal edge cases in production — rate limiting, WebSocket reconnection logic, order state reconciliation, and handling of partial fills and rejections require production experience to implement reliably.
The integration covers API authentication and credential management, REST endpoint wrappers for all required operations, WebSocket client with automatic reconnection and heartbeat management, rate limit handling with request queuing, order state machine for tracking open and filled orders, error handling and retry logic, and a test suite against sandbox or testnet environments. Delivered as a Python or Node.js module with clear documentation.
This service suits trading platform developers, portfolio tracker builders, algorithmic trading teams, and businesses needing reliable programmatic access to cryptocurrency exchange data and trading functionality.
