Blockchain queries and alerts via SMS – zero internet required
Rural Togolese entrepreneurs are unable to run blockchain nodes or access decentralized apps due to unreliable and slow internet connectivity.
AfriSMSChain lets users query balances, tx history, and set alerts by sending simple SMS commands to a local shortcode. Responses come back instantly via SMS with compressed data; for tx signing, it handles 2FA confirmations. Perfect for 2G-only rural Togo where apps fail.
