👋 Hey Product Hunt! I'm excited to share tip.md - the easiest way to add crypto tipping to your GitHub projects. **The Problem**: Open source developers create incredible value but struggle to monetize their work. Traditional platforms take 8-12% fees, require lengthy approvals, and exclude global developers. **Our Solution**: One markdown button that works everywhere GitHub does, supporting 5 blockchains with instant payouts and only 4% fees. **What makes us different:** ✅ Zero-code integration (literally copy-paste one line) ✅ Multi-chain: Ethereum, Base, Solana, Bitcoin Lightning, Celo ✅ Instant payouts - no waiting for wire transfers ✅ Works in GitHub READMEs, blogs, documentation anywhere ✅ MCP server for AI assistant integration ✅ Farcaster mini-app for social tipping **Built for developers by developers** - we use tip.md ourselves and have already processed thousands in tips for the open source community. Would love your feedback and questions! What's your biggest challenge with supporting open source creators? Try it: Add [![Tip with Crypto](https://tip.md/button.svg)](http...) to any markdown file 🚀 #opensource #crypto #web3
