The Opportunity

Problem

Rural Togolese entrepreneurs are unable to run blockchain nodes or access decentralized apps due to unreliable and slow internet connectivity.

Solution

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.

Target Audience

Entrepreneurs in rural Togo pursuing Web3 and blockchain ventures

Differentiator

Togo-specific shortcode with Ewe/French SMS parsing, integrated with local telcos for <1¢/query.
