Payment Assistant

This is a Binance Pay integration that lets Claude process crypto payments through QR codes. It handles both sending (scanning merchant QR codes, PIX support for Brazil) and receiving (generating payment links). The skill is built around a strict state machine with multiple safeguards: it won't let you skip the decode-purchase-confirm flow, treats all API response fields as untrusted display text to prevent injection attacks, and forces explicit user confirmation before executing payments. The documentation is unusually paranoid about security, which makes sense given it's handling money. Works with vision-capable models for direct QR reading or falls back to clipboard/file decoding. If you're building a payment bot on Binance Pay, this gives you the guardrails.
