CCXT TypeScript Development

Overview

CCXT is a cryptocurrency trading library supporting 100+ exchanges. Written in TypeScript, it transpiles to Python, Go, PHP, and C#. When editing exchange implementations in ccxt/ts/src/, you must follow strict patterns to ensure successful transpilation across all target languages.

Most Important Rule: Code must be UNIFIED across all exchanges. Copy patterns from existing certified exchanges, don't invent new patterns.

• Transpilation Rules: Hard constraints for multi-language compatibility (ternaries, types, null checks)
• Exchange Implementation: Adding exchanges, endpoints, error handling, precision
• Build & Test: Transpilation commands, testing patterns, CI workflow
