Documentation: Add integration example for Chainlink CCIP with Python scripts
Description Add a comprehensive Python integration example for Chainlink CCIP (Cross-Chain Interoperability Protocol) to help developers quickly understand and implement CCIP functionality from Python environments.
Motivation Many Web3 developers, especially those working with data science, backend systems, or automation tools, primarily use Python. Currently, the documentation and examples for Chainlink CCIP are heavily focused on Solidity and JavaScript/TypeScript implementations. This creates a barrier for Python developers who want to leverage CCIP for cross-chain operations.
Justification A step-by-step Python integration guide would:
- Lower the entry barrier for Python developers entering the Web3 space
- Expand the Chainlink ecosystem by making CCIP more accessible to data scientists and backend engineers
- Provide practical examples for common use cases like querying CCIP data and initiating cross-chain asset transfers
- Complement existing documentation by covering the full development workflow from a Python perspective
The guide should include:
- Setting up a Python development environment for CCIP interactions
- Basic CCIP operations (data queries, monitoring cross-chain messages)
- Example code for initiating asset transfers via CCIP
- Best practices for error handling and transaction management
- Integration patterns with popular Python Web3 libraries (web3.py, eth-brownie, etc.)
Additional Information Similar documentation improvements in other blockchain projects have significantly increased developer adoption. Examples that would benefit many developers include:
- Python scripts for reading CCIP Router contract data
- Sending cross-chain messages using Python and web3.py
- Monitoring CCIP transaction status programmatically
- Integration examples with popular Python frameworks (Flask, Django, FastAPI)
Hi @USBVadik I’ve started working on this issue and will be adding a Python integration example for Chainlink CCIP as described. The example will include scripts for reading CCIP Router data, sending cross-chain messages, and monitoring transactions using web3.py. Once the implementation and documentation are ready, I’ll open a PR and update this thread to notify you.
Hi @USBVadik and team,
As discussed in this issue, I’ve implemented the complete Python integration example for Chainlink CCIP and opened a corresponding pull request — #20164: docs: add Python CCIP integration example with monitoring and send scripts .
The PR introduces a fully functional example directory containing:
ccip_send.py — Script to send CCIP cross-chain messages
ccip_read.py — Script to read CCIP router configuration and supported networks
ccip_monitor.py — Script to monitor message delivery and transaction status
.env.example and requirements.txt — Environment template and dependencies
README.md — Comprehensive setup, usage, and testing guide
All scripts were tested locally for environment loading, Web3 connectivity, ABI resolution, and dry-run execution. This contribution fully addresses the requirements outlined in the issue by providing a step-by-step, Python-based CCIP workflow.
Please review and merge when possible. Thank you! 🙌

Hi @USBVadik, @patrickhulce, @Outsmarting, @linhbus, and @prashantkulkarni92 —
I’ve completed the full Python integration example for Chainlink CCIP and opened PR #20164 .
The PR introduces a ready-to-run example including ccip_send.py, ccip_read.py, and ccip_monitor.py, plus .env.example, requirements.txt, and a detailed README.md.
It addresses all points in this issue by providing an end-to-end Python workflow for sending, reading, and monitoring CCIP cross-chain messages.
Kindly review when you get a chance — feedback or approval from the maintainers would be greatly appreciated
