The Legandary Super Saiyan
summary
Demonstrates sending Bitcoin over GSM (SMS/USSD) with phone numbers as Lightning addresses like phone@83.mobi, uses Java Card / SIM Toolkit applets to make the SIM act as a hardware wallet, and targets Machankura as an Africa‑centric rollout. Current build signs transactions locally (Schnorr-friendly) but checksum on address encoding is failing and inbound SMS handling is unfinished; a custodial backend exists now but roadmap is open‑source self‑custody with dev kits and a promised two‑week demo.
