Let’s play with Bitcoin Cash using Swift
summary
Shows how to construct a real Bitcoin Cash transaction in Swift using Bitcoin Kit, derive HD keys with BIP39/BIP32/BIP44 (coin path 145) and calculate fees so inputs minus outputs never lose funds. Demonstrates writing a permanent OP_RETURN message that appears in a block explorer, explains SLP tokens integration and zero‑conf low‑fee payments (millions per second for less than a penny), and unveils a points/token prototype called onlypoints that is running as a live demo.
